Setting Up a New Matter Thermostat

Setup, Configuration and Use Installation

OH5.1.1 running on RPi5 configured entirely using MainUI

Lennox recently added Matter to their S-40 Thermostat with a firmware update.

It only supports a few channels and a couple of them either don’t work or I’m not sure what they are used for.

Here is the Thing Yaml

version: 1
things:
  matter:node:afdd086f91:6762373617598723760:
    isBridge: true

      "1#thermostat-unoccupiedheating":
        type: thermostat-unoccupiedheating
      "1#thermostat-localtemperature":
        type: thermostat-localtemperature

And here is a screenshot of the Equipment it created

Signal has no data

Running Mode is always OFF but the HVAC is operating

It’s not clear what system mode is

Here are the Channels in the Thing with some strange data (circled)

There is no documentation from the vendor.

I’m assuming the way it appears in OH is because of their implementation?

Its probably better to post this in the Matter binding thread?

Another hint for you: you can also use any existing “old” thermostats which are not directly Matter compatible and expose them to Alexa using the Matter binding. This can be carried out using items Metadata → Matter and is a great feature.

Thanks

I’m not always sure which thread to post in. You’re right this is maybe more an Matter issue.

I originally posted in another thread about getting the Matter connection working.
