Carrier Cor? TP-WEM01

[thatvirtualboy]

From what I've read, the Carrier Cor (corSmart) is essentially a rebranded Ecobee. I was able to get this plugin installed on Homebridge, successfully add the authorization code in my "Apps" on the Cor login page (everything is basically the same as ecobee).. but when launching homebridge, I get
Not supported thermostat | My home (corSmart

I don't have sensors, just trying to get the Cor setup with homebridge. It's the TP-WEM01 Model which doesn't have native Homekit compatibility. The TP-WEM01-A (which came out years later) is what has native compatibility.

Is this something we can tweak to make work, or am I barking up the wrong tree?

Hello @thatvirtualboy,

I think if the plugin managed to run all the way to this error message, there's a decent chance that you might get it working, but as usual you're on your own there.

Good place where to start hacking is the thermostat model check in platform.js:232.

Have fun!

Thanks for the tip! Will play around

I changed line 231 to read
if (thermostatConfig.modelNumber != 'corSmart') {
and it appears we make progress, but on my homekit app in iOS it shows homebridge as "No Response" (it was working previously, so I'm guessing it's something in the config?)

In further testing, something in the HB config for this plugin is causing Homekit to not connect to HB. I removed the documented data from config.json (so it was as before with just my garage door data), cleared accessories and persist folder, and HB was able to be added to Homekit again.

[thatvirtualboy]

Ok I've narrowed it down some. As soon as I add the App to my Cor's App page (by authorizing it with the code given when starting HB) it fails, and HB stops responding.
Strange, since it seems to be talking with the thermostat and printing the temperature.. but then as soon a I add the app HB fails.

[thatvirtualboy]

I believe it has something to do with the sensors. Since all I have is the thermostat, it causes HB to fail, and/or cause Homekit to not want to connect to HB.. like it fails once it sees it has devices to configure (sensors) that it can't. I've set all the exclusions in config.json to true, except for thermostat temp but same behavior.

[thatvirtualboy]

If I add homebridge before authorizing the app at the Cor's webpage, HB gets added, but says
Additional Setup Required
Add related accessories with "Homebridge"in the manufacturer's app.

[thatvirtualboy]

Well that's my journey so far. We're so close! If I can provide any logs or information to help troubleshoot, please let me know! @vojtamolda

[vojtamolda]

It looks like a fun project and I'd love to take a look, @thatvirtualboy, but I'm not sure when I'll be able to find the time to do it, so I can't promise anything.

[thatvirtualboy]

That you'd find this comical.. I opened an unrelated support case with Carrier regarding the Cor and the support tech's email and sig was plastered with "ecobee Support"

@vojtamolda

I realize this is an old "issue", but I've just started experimenting with HomeBridge and have a Carrier TP-WEM01 just like the one discussed in this thread. I may have gotten further than @thatvirtualboy. I've attached a debug log snippet below that shows the activity when a refresh is requested once every 30 seconds:

carrier cor.log

I have this configured with the default config.json platform configuration, with all 'exclude_*' properties set to false.

The net result is I've got a Temperature Sensor showing up that seems to be reading the correct temperature, but I don't have a Thermostat with the ability to change the usual thermostat related properties.

Seems like we are really close! Is there anything anybody can suggest to get this stubborn device working?

Here is what the accessory looks like in homebridge-config-ui:

That’s awesome you were able to get the temp sensor added in. Definitely a step in the right direction! Thanks for sharing. Unfortunately I’ve abandoned my attempt.
