Hello,
As part of expanding my home automation modules and features I have just acquired the Xiaomi Aqara zigbee3 TVOC air quality monitor module.
It is perfectly detected by Gladys via zigbee2mqtt; the temperature, humidity, battery, and voltage features are perfectly detected and measured but the air quality (TVOC) feature, which is measured in mg/m3, does not seem to be taken into account (or perhaps poorly, because a second « temperature » entry without an icon appears in the device’s features in z2m but no data is reported).
Is there a trick to retrieve this data, do I need to go through a Node-RED script to connect the device to Zigbee? Before digging any further unnecessarily, I’m asking the regulars of this forum…
Apparently you have the room temperature and the device temperature.
I assume it’s this model
I’ll add support for voc
hello @VonOx ,
this looks like that one, the white name is identical.
but the small e-ink screen does not display the air quality info numerically but with leaf-shaped pictograms.
I’ll take the opportunity to give a bit of feedback on the units: it works well for the majority except for precipitation: you put mm/h but I think it should also be mm/day because the stations also provide this info which is closely monitored (notably in rural areas by farmers). Also I did not see a pressure functionality (in hPa) and there is a problem with the wind direction on the compass (retrieved in ° from the stations).
thanks
Erratum, regarding atmospheric pressure I just found it; I had missed it due to
It would be nice if we had the model ( it should be written on it).
So that we know which units the model returns.
@VonOx,
this is therefore a Xiaomi Aqara (TVOC air quality monitor)
on the box the model mentioned is AAQS-S01
temperature 0-+50°C humidity 0-100%
TVOC detection range 0-25 mg/m3
like many devices it also reports battery level and voltage
works with 2 CR2450 batteries
the sensor measures 76*41 mm and has a small e-ink display that shows
