I am using a multisensor ( temperature, humidity, co2, pm2.5, VOC ) , type is
TS0601 by _TZE200_yvx5lh6k.
The values for temp and humidity are perfect, the others ‘seem’ to be reasonable, but there is
something which is strange :
The history diagrams for all three look exactly the same, just different scales.
Either these sensors are fakes or there is something wrong with the integration.
Info : Quirk: zhaquirks.tuya.air.ts0601_air_quality.TuyaCO2SensorGPP
Hello,
I am using a multisensor with the same signature as yours, but I’m not experiencing this issue.
The diagrams show different trends for the different properties.
Maybe yours is defective.
BTW, I noticed that something changed from 2025.2 version and the device custom quirk does not work anymore, giving an error importing zhaquirks.tuya.air.
It seems that a lot has chamged in zhaquirks module, and now the device is recognized without the custom quirk. BUT I have the Formaldehyde sensor constantly at 0.
Maybe it is correct, I’m not sure if the reading is a value below 1 and the ppm unit is expressed only as an integer, hence zero is the result of a rounding.
