[PROJECT] Driver for Connecting to Your Tesla Devices

WARNING: THIS DRIVER IS IN A VERY EARLY STAGE OF DEVELOPMENT.

This driver is meant for connecting to Tesla devices, starting with their Powerwall 2. The end goal is to make it possible for users to check whatever information any of their Tesla devices provide.

In any case, the focus this time is on the local network data you can access from your device(s). As more data is identified, methods understood, and devices supported, they will be added and listed in this Topic.

Most important, here is the driver:
TeslaDriver.groovy
Plus, if you want to use Child devices you also need this driver (this is OPTIONAL, but without it child devices will not be available and you probably will want them):
TeslaChild.groovy

Supported Devices (as a note, I have NO Tesla devices, this is purely being made by information people have provided or is available online):
Powerwall 2: Currently this is designed around the data that a Powerwall 2 supposedly provides.

The driver has data methods for Local Network (using your device's IP) and also the Tesla API. I have NOT been able to test the Tesla API as I do not have a Tesla account (as I have no Tesla devices).

In any case, this driver cannot progress much with feedback or people willing to try it and report how it works with their device(s). Please let me know so I can make it better for you!

@snell First and foremost, thanks for this!

Installed both drivers, and created a Virtual Device (Powerwall) using the Tesla Connect Driver.

Upon saving the device, it gave me some options, and by selecting connect using network IP, I can find no way to enter the IP address. On a whim, I tried changing the network address of the Virtual Device, but that didn't seem to work.

The code indicates that there should be a dialog. Did I miss a step?

Same (THANK YOU FOR STARTING THIS @snell )

Actually irrespective of API or IP connection I don't get any means of inputting login info for my powerwall or tesla account.

oops, meant to replay to the thread, not directly to you @jared.zimmerman!

Ok... Well I definitely need some more error checking in there to prevent all that. Plus I realized I messed up the preferences (I changed some values there but not for the rest...). Revised version coming in a few minutes.

UPDATE: Version 0.1.2 is now posted and should correctly show the Device IP spot for Local Network as well as Email and Password fields for API. This was a goof when I changed the ENUM values to be more human readable. I KNEW I need to change them elsewhere in the code... but forgot before I posted.

Since I have to use a "fake" address to get to a sample, I do not get to use the real methods.

Certainly closer!

I think this is that certificate recovery step.

S.

ok tried LAN and API again

LAN give me : * Status : Local Connection Error

API give me : * Status : CONNECTION ERROR

For API just wanted to mention that there is an "Installer" and "Customer" login, in case there is any opportunity to select one or the other (only Customer works)

Ok. Version 0.1.3 is now posted. I added a bunch of error checking in (was already working that) and it should ignore SSL issues with Tesla's self-signed certificates.

I love this near-realtime feedback!

Yeah, I went to the URL on my bowser, and the certificate authority is invalid. We'll probably have to bypass this.

Really close now:

dev:17932020-05-19 07:52:47.069 pm errorPowerWall - Exception: groovy.json.JsonException: Lexing failed on line: 1, column: 2, while reading 's', no possible valid JSON value or punctuation could be recognized.

I saw that mentioned online. Most people either bypass it or just accept Tesla's certificate as valid and add it to their computer. I get the same thing with the printers at work. In any case, I do not think we can (or want to) add certificates to our Hubitat, so bypassing (ignoring) it for now.

Seems like the best plan. In the Schiavo link, there's essentially an import statement. I seem to recall doing that when I was playing with the Python stuff.

S.

Ps. For my part, its almost bedtime, so real-time might become tomorrow time soon! :wink:

No problem. When you are done, you are done.

Version 0.1.4 is posted. All it does is add a bit more trace logging for Local data. If you can grab what it returns after "Local Aggregate Response"... in the log, that should be what it actually returned. Tough to diagnose a json issue when I cannot see the json that came back. :wink:

Sorry, lots of user error between now and your previous, but I got there:

Ok. There are some differences in structure compared to what I based mine on. It will take me a bit, but this is why real samples are valuable. I will post the update as soon as I can.

No worries at all.
In interpreting the JSON, it might be valuable to know my system has 2 Powerwall 2s and 18 panels plus a Solaredge inverter.

S.

Posted version 0.1.5 now. Not sure if this will help, but I am having it specifically request json content. I had read it would return json, but what it gave you before specifically is NOT json formatted.

The good news is that the data returned only had one element I did not have listed already "timeout"... which appears basically meaningless, but might as well include it.

If I cannot get it to provide nice json to begin with it will require a bit more parsing to make it happy, something I will not be finishing tonight.

Result is definitely different, I don't recall the Solar tag from earlier data: disregard I looked again, it was there.
