What happened?
Integration of the Nous E12 carbon monoxid sensor is not working correctly.
{ "last_seen": "2026-01-15T18:46:59+01:00", "linkquality": 149, "carbon_monoxide": true, "carbon_monoxide_value": 0, "checking_result": "error", "fault": false, "lifecycle": true, "preheat": null, "self_checking": false, "battery": 2, "elapsed": 97 }
The battery shows always 2 % and carbon_monoxid is true (without CO)
Zigbee2MQTT-Version: [2.7.2-dev] commit: d44cdbd
Frontend-Version: 2.6.2
zigbee-herdsman-converters Version: 25.106.0
zigbee-herdsman Version: 8.0.3
What did you expect to happen?
I think this is an parsing error because nous sends the battery status as battery low true/false like Nous E8.
And carbon_monoxid should be false if there is no CO.
How to reproduce it (minimal and precise)
Connect the Nous E12
