webCoRE for Hubitat Updates

Developers Code Share
#1

Overview

webCoRE provides a rich common programming environment and code sharing across different home automation platforms. webCoRE provides an integrated IDE, debug and trace environment for developing, testing, monitoring and optimizing your automations. It also has the ability to create dashboards that can be accessed from different locations. webCoRE is one of the few apps that provides both execution and performance information on your automations.

There is a webCoRE community that has many example pistons that can be imported, as well as get questions answered.

  • webCoRE on HE makes it much easier to move your existing automations to HE from SmartThings, and run all your pistons locally on the HE hub.

  • This is the latest port of webCoRE onto the HE platform and has many optimizations for HE.

  • Simple pistons normally execute on HE in less than 15ms (which is a dramatic improvement vs. operations on SmartThings which is commonly > 150ms for the identical piston)

  • webCoRE is integrated with homebridge V2 and Echo Speaks, both of these apps can execute pistons or trigger on piston execution

Current Release Update February 9, 2021

  • further optimizations
  • Updates for http requests that return binary data
  • Updates to 'stays unchanged' operation to cancel properly
  • updates for setLevel command on switch to support command calls with duration for transition
  • corrections for running multiple webcore instances
  • added lifx support from original webCoRE

Previous Release Update January 23, 2021

  • Further JVM optimzations
  • Fixes for IDE displays of various 'stays' triggers
    • correction of trace information for webCoRE IDE
    • updates of wording for 'stays' triggers to describe behavior better
  • updates for $sunrise, $sunset based on new HE apis
  • correction of incorrect types used for time parsing
  • use of new HE APIs for trace, exceptions (if running 2.2.4 or later HE firmware)
  • updates to webCoRE IDE (on staging.webcore.co, or if you run local) for dark mode theme selection

Previous Release Update December 8, 2020

  • added $longitude, $latitude, $zipCode and $tzId based on current hub settings.
  • system variables are now sorted in IDE display
  • for users running local web server for webcore, the html / css has been updated (use the repo listed in this note)
  • Updates for homebridge V2 can execute webCoRE pistons.
  • There is a new driver for users of $weather, that provides an event when $weather is updated - so pistons using $weather can be event driven, to run after an update occurs to $weather variable. The piston will need to decide what changed for values, the 'updated' event provides notification that webcore updated $weather. If you use HPM, you have to use 'modify' to select to add this device handler. Example: webCoRE for Hubitat Updates

Installation and Updating

Notes on Updating:

  • it is good practice to update the webcore-piston.groovy code first, then the webcore.groovy last when installing new files in HE.

  • Hygiene after an upgrade: going into the Hubitat Console and selecting: "Apps" -> "webCoRE" -> "Settings" -> "Cleanup and rebuild data cache" is a good thing to do.

  • HE has a limitation on the amount of data that can be returned on a http call from a server (128KB - headers) to its cloud endpoints.

    • This can affect you if you are running backups from the webCoRE dashboard using webCoRE cloud servers, as large lists of pistons could be requested to be uploaded for backup. Doing full hub backups from HE console, or backing up pistons one at a time from the webCoRE dashboard are the workarounds.

  • if you are running local webCoRE dashboards (this is an uncommon optional deployment described in note 2 of this thread), I would suggest updating webcore-piston.groovy and webcore.groovy and, ensure everything is ok with any code updates there, before updating your local dashboard.

    • this will allow you to more easily check things out in a new release.

Details on the webCoRE port to HE

  • Here's a link to a thread that has links to the original github webCoRE code that was forked for use with Hubitat. It was this version of code that I started working with to optimize for Hubitat. Patched webCoRE for Hubitat (2018/09/09)

    • While a noble goal to keep the source code (groovy) in the hub the same as ST, this is impractical because of sheer code size, numerous platform differences architecturally, and the inherent higher horsepower ST requires running in the cloud.

    • Fixes found during the HE optimizations have been provided back to the ST webCoRE team to resolve bugs.

      • separate hub code makes QA and release management easier, both on developers and users (users on one platform don't get changes destined for another platform).

    • we keep the source / apis common for the webCoRE servers so that interoperability and piston sharing can work between platforms.

Features in this code :

  • This version is less overhead on HE platforms:

    • state (storage) reduction for webcore pistons

    • many parent/child calls have been removed

    • Added new trigger capabilities

      • if Device receives attributeValue or if Device gets attributeValue (for momentary devices like buttons)

        • receives / gets triggers have the piston only subscribe to attributeValue (vs all state changes) of the attribute. (ie switch.on (only on events of switch) vs. switch (all switch state changes). This is also interesting for buttons (gets 1) to only receive button pushes for button 1.

      • global variables as triggers only wakeup pistons subscribed to that variable Screen Shot 2020-12-20 at 10.19.41 AM

      • ifttt events only wakeup pistons subscribed to that event

      • Adds ability to have a piston trigger from a HE system restart event

        • this is not typically needed for proper piston operation, but can be helpful if you want a piston to check modes or other state that may not be correct (changes happened while hub was down).

        • this is done 'if System Start event occurs'

          • so select a virtual device System Start, and the trigger verb 'event occurs'
          • note that just after reboot, the hub is 'busy', so you may want to limit / delay the actions you take

    • reduced watchdog activity

    • reduce sending of location events (causes Hub db activity)

    • Should have less resource usage and execute statements much faster on Hubitat, especially if Parallel execution is turned (left) off for your pistons.

    • uses Async http calls for http commands (http, email, ifttt)

    • Pistons that run a long time will automatically "be nice" and release/share the cpu so other things can run / operate. Adds pauseExecution() for long running pistons to avoid 'hangs' of Hubitat hub due to compute bound applications. webCoRE will terminate long running pistons after 40 seconds runtime for a single event.

    • Reduced thread usage by pistons significantly by quickly queuing activities that can be delayed

      • Note Hubitat can run 4 threads at a time (cores) and has about 20 threads available for event processing.

  • Added new functions from latest webCoRE master

  • Has an HE version number in addition to webCoRE version number to understand what is deployed.

  • Ability run rules from Rules Machine.

  • Bug fixes for time handling, sunrise, sunset, daylight savings time.

Note:

  • The piston bin (backup code) is located in state and settings variables for each piston (you can see these in Hubitat console by "Apps" -> select settings gear next to the application /piston.)

    • The backup code is also available in the webCoRE dashboard when you select the piston

    • it is good practice to enable automatic piston backups

webCoRE Differences / Restrictions (vs webCoRE on SmartThings platform):

  • Buttons operate differently in HE than ST, so when importing pistons from ST, these portions will need to be adjusted to the HE button devices and attributes.

    • Hubitat's button implementation

      • This is a simple edit to use holdablebutton, pushablebutton as the attribute vs. button after import.

    • Some users have found they needed to recreate the if statement for a button if ST import brought in a device subIndex.

  • HE port has removed a lot of source comments (that caused problems compiling/saving on Hubitat)

  • Smart Home Monitor (SHM) does not exist in HE, but it does have Hubitat Safety Monitor. This is supported by webCoRE. Hubitat Safety Monitor API

  • Hubitat does not support $twcweather, so you would need to use a weather device for Hubitat with webCoRE or the experimental $weather support (below)

  • There is experimental support $weather variable access in webCoRE based on openWeatherMap (free), darkSky data (free but going away due to Apple purchase) or apiXU (payment required apiXU.com).

    • This requires installation of the webcore-storage.groovy app (HE Console -> Apps Code)

    • Enter your openWeatherMap, darkSky, or apiXU key in the webCoRE app (HE Console -> Apps -> webCoRE -> Settings). $weather should be populated for your pistons.

    • This link has information on viewing $weather data: webCoRE for Hubitat Updates

    • There is a new driver for users of $weather, that provides an event when $weather is updated - so pistons using $weather can be event driven to run after an update occurs to $weather variable. The piston will need to decide what changed for values, the 'updated' event provides notification that webcore updated $weather. If you use HPM to install, you have to use 'modify' to select to add this device handler. Example: webCoRE for Hubitat Updates

  • sendPushNotification command does work, it requires:

    • HE mobile app, pushOver, twilio or some other notification driver on HE to be installed & configured on HE and this driver set for notifications in webCoRE (in the HE Console, Apps -> webCoRE -> Settings).

  • HE has removed SMS support (Previously it limited SMS messages to 10 per day). You can subscribe to a separate service and use an appropriate device handler.

  • webCoRE on HE uses the 'us' (USA) region webcore servers (when using dashboard.webcore.co). I have not found a way to auto detect region on HE, and HE currently only has USA servers. (if anyone knows differently/more let me know via private message)

As mentioned in other notes, it is a good idea to:

  • Avoid enabling parallel execution in piston settings (under options when editing a piston), this should not be needed as Hubitat has much less available CPU than a cloud. (and this is a big hog of hub resources)

    • This causes webCoRE to use atomicState much more (which is slow in Hubitat)

  • Control use of logging, both in code in your piston, and in the webCoRE dashboard when enabling logging on pistons. It is a good idea to leave it on "none" or minimal once you are done debugging a piston to reduce load on the hub and the database.

    • with the state size reductions in webCoRE, the logging setting is likely the largest consumer of state (db space)

    • This link has some performance information related to logging: webCoRE for Hubitat Updates

  • Piston Design paradigms part 1: if a lot of things need to happen near the same time:

    • If you need a bunch of Pistons to run at the same time (say nightly or to run off the same trigger), you have a couple of design choices:

      • you can have a each piston with its own timer/trigger "At midnight..." (MORE OVERHEAD, as it causes a lot of threads to be consumed at the same time in Hubitat)

      • you can have one Piston called nightly work (or event work), and it calls each of the other Pistons that need to be run (BETTER in that less threads will be consumed (assuming you leave wait option set to true))

  • Piston Design paradigms part 2: In many pistons, you may be subscribing to more device attributes or states than you intend. If a piston is dealing with motion (and controlling a switch), it may not need to be subscribed to the switch (but commonly you may see it is).

    • Look for the "lighting bolt" in your piston code (in webcore dashboard/IDE) and ensure you need all the subscriptions that you see. These cause the piston to wake up (and consumes a Hubitat thread) for each wakeup.

    • Key is to choose your comparisons correctly (trigger vs. condition) in your pistons - if the piston has a trigger, then conditions are not subscribed to.

  • Piston design paradigm part 3: In many pistons, you may read / compare the same device attribute repeatedly. In most cases the attribute will not change during a single event execution. If this is the case, you can at the start of the piston access/ store once the attribute value to a variable, and use the variable throughout execution. Device attribute access is slower than variable access.

  • avoid enabling log piston executions in the webCoRE app as this adds a bit of overhead on the hub and database (this is a webCoRE app setting; not a piston/code dashboard setting).

    • If you have applications that want to trigger based on a piston execution, this does need to be enabled. Examples include Echo Speaks and Homebridge V2 (if you need this feature).

Installation Notes:

Reporting issues:

  • Apologies in advance if you have problems

  • A private message (here in this discourse forum) is many times best, and if you have a sample piston that shows the issue and/or logs, this makes things much easier to diagnose/fix.

If you need general webCoRE assistance on coding, examples, etc, the webCoRE community forum is a good place to visit, find programs you might reuse, have discussions with experts, etc.

Additional details on how things work:

webCoRE Operations

Your pistons execute locally and if the webCoRE servers/internet are down, pistons keep working (unless using one of the below mentioned webCoRE server functions).

  • It is possible to run the webCoRE [dashboard] server locally (see below)

Your piston is stored in HE hub (inside the piston child application). When in the webCoRE dashboard and you want to edit a piston, the webCoRE dashboard requests the code from HE, and when you "save", it stores the code back into HE into the piston.

  • This is why it is good in general for HE to take regular backups on your hub and store off your hub.

webCoRE dashboard (server) functions

webCoRE uses the cloud webCoRE servers for webCoRE dashboard operations (when you use the cloud instances of webCoRE dashboard such as dashboard.webcore.co or staging.webcore.co). The webCoRE cloud servers allow:

  • you create/edit/debug pistons (regardless of your location)
  • share, import pistons with others
  • cloud backup and restore of pistons
  • local backup and restore of pistons
  • show the dashboard / tiles of your pistons
  • provides some services such like ifttt (outbound) and email (outbound), $nfl functions
  • display of fuelstreams data (storage of fuelstream data is local)
  • Displays detailed performance data and graphs of your piston operations, both most recent and historically.

staging.webcore.co is the newest / beta of the wc servers (WC team puts updates there before they release them). You generally do not need to use this site unless instructed to, as it may have code that is not fully tested/released.

Piston Backups

  • When you backup your HE Hub, you do have a backup of all apps, pistons, and settings

  • webCoRE contains the ability to backup pistons locally (to the system you are running your browser on) from the webCoRE dashboard.

    • due to the HE platform limitations on message response size to http requests, you typically have to backup pistons 1 at a time to store locally.

      • specifically HE platform limits responses to (128KB-header sizes) in size, so it may be possible to backup 2 or more smaller pistons, or only 1 large piston in a single request depending on the size of the individual pistons.

Miscellaneous Details:

  • webCoRE will terminate a piston execution if it runs for more than 40 seconds for a single event - so in addition to the "being nice", this should terminate a runaway piston.

  • When the webcore dashboard is open at the main dashboard page (listing your pistons), it updates every 10 seconds with Hubitat. While not a lot of overhead, be aware that it is updating

    • if you open the "Dashboard (beta)", there is much more overhead on Hubitat (while it is open)

  • Time Handling

    • HE platform handles time string parsing differently than ST. If you find time strings are not converting properly please report this (ideally private message, and logs and/or example piston).

    • When scheduling things that you want to run on "day changes" - for example midnight:

      • keep in mind that schedules can run up to a second or two early, so if you want to ensure it runs at or after midnight, set the piston to run "Every day at 1 minute after midnight", to ensure it runs on the new day.

    • the design paradigm of having a single "nightly" piston run, and it calls other pistons is more friendly to the resources on Hubitat.

    • If you are in an area that has daylight savings time (DST), Be careful scheduling work to happen during the change periods of DST, as things may not run, or run twice depending on the DST change happening. - 00:01 - 00:58 or 03:01 and later may be better choices.

  • If you need a larger application, you can use multiple pistons, and have a main piston call the sub-pistons. Again, leave the wait = true on when performing "execute piston"

    • do note:

      • to pass data to a piston, you can use arguments on the piston call, or global variables.

      • to get data returned from a piston execution, global variables are often the best choice.

      • note that a piston can subscribe to a global variable change. (globalvariable changes). This design paradigm can make it easy to not worry about the loading comments below.

        • global variables are "loaded" when a piston starts, and saved when a piston exits, so if:

          • Piston A calls piston B, and B modifies a global variable, piston A will not see the change until the next time piston A executes.

          • Piston A modifies a variable and calls piston B, since A has not exited yet, the change to the global variable is likely not to be seen by B until B runs again after A has exited (and saved changes)

  • If you are using older zwave devices (and some zwave plus devices), these devices may not report physical switch state changes in a timely manner, so you may need to add a refresh in your pistons before checking state for conditions.

    • For triggers or conditions, Zwave Poller should be enabled for these older devices. This is due to ST vs. HE differences in handling of older zwave devices. If you choose Zwave poller, you won't need the refresh commands in you pistons:

      • In many cases, replacing these older devices will be your best option to have HE function efficiently and have a well-operating mesh.

      • Device Status Not Updating on Manual Change
        Z-Wave Poller only supports Generic Z-Wave Dimmer and Generic Z-Wave Switch device handlers.

  • Version numbers

    • interoperability with the dashboard.webcore.co site requires compatible version numbers for dashboard server interactions. For server interactions webcore reports the webcore version number understood by the dashboard.

    • An HE version number is also in the code for webcore.groovy and webcore-piston.groovy. These are checked that they are the same, but they do not provide an update notification of newer version available (only the webcore version number is checked for the notification)

Running a Local webCoRE Server

It is possible to host the webCoRE web server files (html, css) locally (on your own computer in home, such as a raspberry PI).

This is an advanced/complex configuration, and when setup properly removes part of the webCoRE web server cloud dependencies - shifting the dependencies to your local deployment. This feature is only available on the HE port of webCoRE. Note that this is for webserving the IDE web pages, other webCoRE server functions (piston sharing, email, ifttt outbound, $nfl, store media still use the webCoRE servers)

  • Because your local copy is providing the web server server files, you need to ensure it is kept running, and you should run webCoRE or HE backups to ensure no service or data loss.

  • If you want remote access to the webCoRE dashboards, or have multiple locations and want to share pistons across them (when running a local webCoRE server) you have to enable access to the webCoRE server on your local network to the desired locations (VPN, remote desktop access, etc.)

  • It is not required to host the webCoRE webserver files locally and doing so is not likely to change performance for most folks. For information/discussion on running the webCoRE servers locally, see the thread: Patched webCoRE for Hubitat (2018/09/09)

    • Note you should use the files from the latest repo for webCoRE in note 1 of this thread (not the older files in the older instructions links as the web server files have changed since those notes were written). webCoRE can be hosted with superstatic (NPM package), and it has a superstatic config file as part of the repo if you clone the repo in note 1.

FuelStreams

The webCoRE dashboard can display / graph data. Fuelstreams is a groovy module to store data for piston fuelstream requests locally on the HE.

Updated August 15, 2019

Significant updates to webCoRE on HE to reduce overhead and improve performance

As always, before upgrade, do take backups of your hub, and store the backup off the hub on your computer. (HE console -> Settings -> Backup and Restore)

It is good practice to reboot your hub prior to upgrading, and to let it settle its internal DB for a few mins, then install the new webCoRE version (HE console -> Settings -> Reboot Hub)

Install the main webCoRE.groovy application last when updating the groovy components (HE console -> Apps Code -> webCoRE Piston; webCoRE Storage then webCoRE (main app).

After upgrading recommendation:

  • go into the HE console, Apps -> webCoRE and then scroll down to hit "done"
    • wait about 1 minute for updates to occur as part of the upgrade
  • open the webCoRE dashboard/IDE in a new browser window
  • THIS SHOULD NOT BE REQUIRED WITH OCT 10 and later updates select a small piston so that db uploads to the IDE will not exceed HE limits. It is possible this small piston may need to be loaded twice (without editing the piston) for all the IDE uploads to complete. This may occur if you have a lot of global variables, variables, or devices. HE logs (HE Console -> Logs) will show if you need to load twice or not.

Improvements

  • much improved performance due to many optimizations - These together can reduce overhead by up to 50%
    • reduction of state usage (HE database)
    • improved locking performance
    • code optimizations to improve performance
  • Added new trigger capability
    • if Device receives attributeValue or if Device gets attributeValue (for momentary devices like buttons)
      • receives / gets triggers have the piston only subscribe to attributeValue (vs all state changes) of the attribute.
  • updated version numbers to match updated webCoRE release

      • entering your apiXU key in the webCoRE app (HE Console -> Apps -> webCoRE -> Settings)
    • data format is apiXU data format (pistons need to be modified to this data layout)

Updated May 12th, 2019

  • Fix for subscription publishing (if you think you hit this issue, pause/resume of the piston, or edit/save (both in webCoRE dashboard) will resolve.

Updated March 30, 2019

  • Key update is code changes to dramatically reduce state (storage) usage by webcore pistons

    • side effect to be aware of once this new version is installed, you cannot easily go back to an earlier version of webcore on HE due to the state changes / reduction in the piston.
    • piston backups, restores from webcore server work as normal (no changes).

  • Benefits:

    • I have observed startup, and atomicState accesses to be much faster (likely due to having to load/store much less state during startup and piston end)
    • Many operations run faster, especially ones that accessed atomicState and piston startup

  • How to install: (this is consistent with instructions below)

    • Do restart, and backup your HE Hub (download the backup to store off your hub)
    • Install webcore-piston.groovy, then webcore.groovy under "Apps Code"
    • After installed and operating, you should take another backup of your hub and download the backup to store off your hub.

Updated March 23, 2019

  • ifttt events are directed to specific pistons vs. all pistons
    • This change requires you on installation to this March 23 version to pause pistons that subscribe to ifttt events, and then after the groovy code update is complete, unpause them so that the subscriptions are properly updated by the new code. This is done in the webCoRE dashboard, selecting each piston that subscribes to ifttt events / callbacks.
  • time parsing fixes for iso 8601 strings
  • this release has beta / experimental display of local fuel streams in the webcore dashboard. (currently requires staging.webcore.co as dashboard URL)
  • small bug fixes

March 20th changes:

  • Avoid duplicate commands to physical devices
  • Additional time cleanups

March 16th changes:

  • command cleanup and ensure webcore dashboard updates with command changes
  • use this version to avoid issues with recent Hubitat platform changes

March 15th changes:

  • Many time handling and DST changes based on bugs found in original webCoRE

March 14th changes:

  • Global Variables do not wake all pistons on change (only pistons subscribed to that variable)

    • This change requires you on installation to this March 14 version to pause pistons that subscribe to global variables, and then unpause them so that the subscriptions are properly updated by the new code. This is done in the webCoRE dashboard, selecting each piston that subscribes to global variables.

Taking over this note for instructions

You can see the $weather data format by

  • make sure you installed the webCoRE storage app (it gathers and updates the $weather variable)
  • setup the webcore main app to enable $weather and your source and key, and done your way out.
  • Go to the webcore storage app (HE console -> apps -> select the webcore storage app) and click on "dump weather structure" - this will let you see what you have to work with based on your source
  • In your piston, that is accessed via $weather... (of what you see in the dump).

The different sources for $weather have different data, formats/spelling of variables, so hence you need to see the dump.

There are many example weather pistons in the webCoRE forum (most of these are for $twc as a source which ST uses (which is a paid service, so not on HE), but these examples can help you start with something and then adjust the data reference).

The storage app does attempt to add icon references to the $weather data as well as a $weather.weatherType variable to give you the source setting into the piston.

Another note - many times $weather data has times embedded as integer numbers (these could be seconds since epoch, or milliseconds since epoch). HE webcore can make these time or datetime directly (ie dateTime(value)) vs. all the gyrations you may see in ST pistons to fix time as numbers...

On webCoRE and hub stability:

I get this warning and even though I cleared the cache and restarted the browser it won't go away.

A newer UI version (v0.3.10a.20190223) is available, please hard reload this web page to get the newest version.

#5

I think for some reason it’s looking at the ST value?

#6

on HE make sure you have updated both webcore.groovy and webcore-piston.groovy.

If you have done this correctly, you can then go into Apps -> Webcore and hit done

The webcore dashboard checks the webcore version number. The code (webcore.groovy and webcore-piston.groovy) check the HE version number (that they match) - this would show up in the HE dashboard under "Logs" if there is a problem.

Not working.... I must be doing something wrong.

i dont care webcore can suck it

Updated version today with a few fixes.

See note 1 in this thread

#11

for anyone using local fuel streams on HE,

There are fixes pending testing on the staging.webcore.co dashboard site. (do note these are unreleased and under testing) that enable display of local fuel streams in the webcore dashboard -> "FuelStreams"

#12

You can just ignore this.

#13

It normally should only show up once if the webcore servers are updated.

If you are running a local copy of the webcore servers, this will continue to come up until you update your copy of the webcore server.

Generally older server and newer groovy files should work, however some features may be missing (if this message continues to come up).

As stated in the instructions in message 1 here, when updating (potentially groovy and local webcore server) it is good to update one thing at a time, so you can more easily checkout that everything is good in your environment (ie do groovy first, run for a while, then do your local webcore server).

If we are updating to this version from an old version (pre 2019) do we have to do all the installation workarounds listed in the previous versions also? Do we have to step through and install all the previous versions first? Or can we jump right to this version?

#16

You should be able to go straight to it.

#18

Hi, I just try to install : webcore-piston.groovy in this link : webCoRE/webcore-piston.groovy at hubitat-patches · jp0550/webCoRE · GitHub

When I hit Save on HE, it say : Metadata Error: Parent App 'ady624:webCoRE' not found on line 301
I can not save this app ! Please help. Thanks.

#19

Just like it says, you need to install the webcore app code 1st then piston.

When I open the Dashboard Webcore on HE, and hit new piston, nothings happen! Did I miss something?
Thanks a lot for your help.
