Failed to Add Matter Device

Running OH5.1.1 on RPI5 configured entirely with Main UI

Trying to add a Lennox Thermostat to OH

I believe I set all the ipv6 prerequisites

Created a Controller and tried pairing the Device but getting a failed checksum error

Here is how the pairing code is represented on the device, I tried with and without hyphens

I was able to add this device to Alexa (Echo Show 8) and Apple Homekit.

The thermostat vendor just recently add Matter support with a software update. The thermostat is connected by WiFi to my home network.

Any ideas on an approach to troubleshooting?

It looks like you inverted two of the first four digits when entering the code in OH. :upside_down_face:

You put “0715”, the code picture says “0175”.

And a pairing code can be used only to pair with one controller, you can’t use the same pairing code to pair the device with many controllers.

In the Apple or Amazon app there is an option on the device to generate a new pairing code which is valid for ~15 min, that should be used in openHAB (just as openHAB can generate a code to add to another system). Hyphens are optional, and won’t make a difference (just for making it easier to read).

Entered the pairing code correctly and the thermostat paired as expected!

It would be a useful enhancement if the iOS (or Android) app could use the camera to capture the QR code of the target device. That would help users avoid the problem that I had.

A Thing was created with 6 channels which need further investigation to see if they are useful, since there is no documentation for the device that I can find.

I will start a new thread for discussing the device.

Thanks all for your help!

AFAIK, this feature is planned, but not ready yet.

Those will be the standard thermostat endpoints, and should be listed on the table of all channels in the readme for thermostats and temp.

Regarding mobile , we are holding adding using the camera and Bluetooth until we are a member of the thread alliance , apple and google will not permit apps to have that feature without membership.

Is OH planning to become a member of the alliance?

Seems like there are some low-cost tiers.

I’m not sold on Thread yet but Matter is a great step in the standardization of device control protocol.

Yes, i am planning on membership. Thread is actually a wonderful protocol, especially when paired with TBRs (multiple), especially in larger installations where zigbee and z-wave have really struggled. The problem right now is there are very, very few TBR options out there, so we are another year away (:crossed_fingers: ) until that changes and many more devices like APs and even stand alone TBRs hit the market. I run a couple of 10$ (16 euro right now on amazon) ESP32H2 routers in my production setup and have been pretty impressed .

Just saw them on Ali-Express for half that price…..

Yeah that’s the “I wan’t it tomorrow at 7 am” tax :grinning_face:
