[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

@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
