1. git clone https://github.com/project-chip/connectedhomeip
2. cd connectedhomeip
3. cd examples/air-quality-sensor-app/linux
4. gn gen out/debug
5. ninja -C out/debug

7. Pair the Matter virtual device in HA

Steps to reproduce

Trigger event using air-quality-sensor-app event named pipe

You can send a command to air-quality-sensor-app to trigger specific event via air-quality-sensor-app event named pipe /tmp/chip_air_quality_fifo*.

user@matter-vm:~$ echo '{"Name":"AirQuality","NewValue":3}' > /tmp/chip_air_quality_fifo_68910        user@matter-vm:~$ echo '{"Name":"TemperatureMeasurement","NewValue":18}' > /tmp/chip_air_quality_fifo_68910
user@matter-vm:~$ echo '{"Name":"TemperatureMeasurement","NewValue":1800}' > /tmp/chip_air_quality_fifo_68910
user@matter-vm:~$ echo '{"Name":"RelativeHumidityMeasurement","NewValue":60}' > /tmp/chip_air_quality_fifo_68910
user@matter-vm:~$ echo '{"Name":"RelativeHumidityMeasurement","NewValue":6000}' > /tmp/chip_air_quality_fifo_68910
user@matter-vm:~$ echo '{"Name":"CarbonDioxideConcentrationMeasurement","NewValue":400}' > /tmp/chip_air_quality_fifo_68910
user@matter-vm:~$ echo '{"Name":"TemperatureMeasurement","NewValue":1850}' > /tmp/chip_air_quality_fifo_68910

I think what is going on is that the Air Quality sensor, which was added in Matter 1.2, has some cluster overlap with the Matter 1.1 Temperature Sensor and Humidity Sensor, so what you are seeing is that HomeAssistant does include the two sensor types from Matter 1.1, but has not yet been updated to further add all the Sensor types from Matter 1.2.

@marcelveldt Do you know if this new type of sensor (from Matter 1.2) will be integrated in the near future?

As soon as actual devices will be available it will get more prio - until then: low prio as we're already swamped with enough work. I would have taken a stab at it if there was a ready made example available such as a firmware to flash on a ESP32 or a docker image or whatever. Now I need to build the example from scratch which just takes too much time I dont have atm, sorry.

Thanks for your reply.

Hi, I'm working on a Matter Air quality sensor and would love to help get this functionality into Home Assistant.

We have a functional prototype CO2, PM2.5, TVOC, NOx(tbc), Temperature and Humidity sensor. We'd like to open source this sensor at some point (still quite a bit to do), to allow people early access to "home-brew" devices but also because the Matter certification looks prohibitively expensive for a company as small as ours without a current consumer offering.

I tested our sensor with Home Assistant and hit the same issue as described. I had a quick look at the code (I've not looked at the code or contributed to Home Assistant at all before) and was able to add the sensor data to the Matter integration (see below), my complements to the authors for designing in a way that made this as easy as possible.

I've opened a PR #108173 in the hope that this will be useful.
