zha-device-handlers: [BUG / Device Support Request] Smart Air House keeper TS0601 _TZE200_dwcarsat v2

See https://github.com/zigpy/zha-device-handlers/issues/1313 for technical info

The current implementation isn’t 100%. It assumes it’s the same as the _TZE200_ryfmq5rl and _TZE200_yvx5lh6k devices but it isn’t.

The _TZE200_dwcarsat actually has six sensors.

  • Temperature - 0-60 °C
  • Humidity - 0-95%
  • CO2 - 0-1000 ppm
  • Formaldehyde / CHOH (CH2O) - 0-10.00 mg/m3
  • PM2.5 - 0-1000 ug/m3
  • VOC - 0-99.9 ppm

Most of the above are visible, however, incorrect:

  • VOC Shows a value of 0 constantly measured by µg/m³ which should be the PM2.5 measurement.

  • CO2 Currently shows a value between 0 and 10 measured by ppm which doesn’t really match any “normal” situation. Not sure what this value should stand for. It might be the VOC

  • Formaldehyde / CHOH (CH2O) Currently shows a value of 350-400 measured by ppm which would be deadly and definitely not a normal situation. It looks like this might be the value that is meant for CO2.

  • PM2.5 Not shown at all.

Can confirm that I’m having the same issues with this device. watching

So, I have this sensor too and also didn’t have anything other than VOC right after it is paired.

Other sensors appeared only after HA restart and CO₂/HCHO sensors are swapped. PM2.5 is missing as well.

Can confirm under ZHA I’m seeing similar issues with the TZE200_dwcarsat TS0601 device not showing all the sensors and the data being mismatched.

I have the same model and only see one sensor - Voc_level - any idea why I can’t even see temperature and humidity?

Well nothing suprise me with these cheap sensors. I took a look inside and can confirm in my 6in1 there are only 3 sensors.

@MattWestb Yep looks like it’s handled there. Also looks like this is an issue that is also happening at Zigbee2MQTT: https://github.com/Koenkk/zigbee2mqtt/issues/11033

Hi @LittleFox94 A Formaldehype value above 100 ppm would be deadly 😉. The exposure limit is 8 hours for 0.75 ppm and 15 minutes for 2 ppm (on the workfloor).

Your Formaldehype value probably stands for CO2 which is a normal “daily” value. Hence opening a window won’t change it very much.
