Aqara TVOC air quality monitor problem

Hi,

I’m running the following:

  • Home Assistant 2022.7.7
  • Supervisor 2022.07.0
  • Operating System 8.4
  • Frontend 20220707.1 - latest
  • CONBEE II - latest firmware
  • Mosquito Broker integration is installed as well as the Zigbee2MQTT addon. Both with the lastest version available.

I have 1 Aqara TVOC air quality monitor device. The first time I installed the TVOC device, it worked properly for a couple of days. Then suddenly it started reporting ‘none’ or ‘0’ for all its entities. The payload was reduced to this:

{
    "battery": 0,
    "linkquality": 255,
    "voltage": 0
}

Despite multiple factory resets of the device, nothing changed.
I took the device on another HASSIO installation and it worked properly, showing the following payload:

{
    "battery": 70,
    "humidity": 48.38,
    "linkquality": 167,
    "temperature": 23.71,
    "voc": 14,
    "voltage": 2900
}

I took it back to my normal installation and it still does not work.

Comparing the Zigbee2MQTT settings on both installations, they look identical. There is nevertheless a difference in the cluster tab. On the working installation, it shows the following:


while on the faulty installation it shows:

I have no clue what it means.

I’m lost and wonder if anyone would have suggestions for how to investigate/resolve my problem.

Many thanks

Bought a cheap aqara hub and updated the firmware. Now it works.
