Node-Red

I know, right?!

So I didn't find any documentation, but here's how I'm doing it in my .NET Core code. Basically whenever the websocket sends an event, I deserialize it and raise it as a System.Event in my code, so then I can look at all my automations and see if any of them subscribe to events from the device that sent it.

Guess we are meant to be smart enough to figure it out ... looks like you are making progress.

Thanks for sharing!

I have way too much code in node-red! In fact I have just bought an HE in order to remove all but the most essential rubbish. Some of the things that are easy in RuleEngine are messy in node-red, though you do find yourself repeating "patterns".

Stuff I really really want to remove from node-red

  • the Google Home "integration" implementation which took me a long time to get stable.
  • The simpler monitoring (e.g. is washing machine on, motion lighting),
  • all the weird home built device integration stuff (eg 6-LED Information panels which is 150 nodes on its own)

And other automation stuff I never got around to.

Here's a rough copy of a sketch that integrates Hubitat, MQTT and Home Assistant. It's not very well documented, but you should be able to work with it if you know Node-Red.

The Config node at the top needs to be tweaked for your installation of the Maker API App (Hubitat IP, Maker API App ID and Access Token.) You'll also need to set your MQTT server in the two MQTT nodes and may need to change the url on the websocket listener.

From there, it's just a matter of setting up the Maker API App with the devices you want to control and setting up Home Assistant for your MQTT broker and enabling auto discovery. You can run everything using HASSIO on a raspberry pi or VM and use the MQTT and Node-Red Addons.

#25

Hey thanks @chris, I have tried this and it's working pretty well. I previously created a similar nodeRED flow converting the 'homie3' MQTT discovery protocol into HomeAssistant's discovery protocol (homie3 is a vendor agnostic alternative to the HA MQTT discovery protocol).
This was really to link the Athom Homey home controller into HA, there is an app that does the reverse too i.e. HA devices into Homey.

Very interested in this Chris as I would like the same. I am not sure it will be too easy via hub link - even though that's ideally where it should be done to keep things tidy. Such a shame to have to create yet another Hubitat link app that does almost the same things .. via virtual devices.

keep me posted... Kevin


#26

Thank you very much for sharing Chris! I've only been running it for a few hours now but already like the results. I had quite a few issues with the MQTT bridge Hubitat-HomeAssistant a few weeks back which made me try local HA zha and z-wave. I upgraded to the lastest Hassio and it messed up my zigbee buttons (which barely worked to begin with). So I decided to put the hubitat (Nortek) USB zigbee stick back in the hubitat and try to make them talk to each other again. And here we are.... Thanks again!


#27

@chris
This is brilliant
I wish to keep my NodeRed installation on my HA and use for interface and then hubitat to slowly replace the WINK2.... but if I can run both alongside eachother with the HA controlling both = heaven.


#28

HI @chris
I imported the NodeRed flow into my HA installation and I see the config node being set as unknown.
"This node is a type unknown to your installation of Node-RED."
What am I missing for a pallet?

Ok I tried installing the following:


#29

That should be the right one. I use that node to make it easier to share things, but setting flow variables in one place right at startup without having to edit any files.


#30

Does this go from:
Hubitat Maker API -> Node-Red -> MQTT Broker -> Home Assistant?
Trying to follow this.
Is it bidirectional?


#31

@chris does this work with the Mosquitto broker as well on HA?
also echoing @keithcroshaw here is it bidirectional?
