Tuya TS0601 air quality sensor request for support

[daserra23]

The device only creates temp, humidity and link quality devices at the moment. Missing is CO2, VOC and formaldehyde. In that is very cheap and works very well in zigbee2mqtt I thought it might be good to make it available via the plugin. I am happy to provide and information that might enable this.

During device creation I received the following errors;

2021-11-10 18:28:09.733 Error: (ZIGBEE) Device creation failed, Domoticz settings prevent accepting new devices. 2021-11-10 18:28:45.229 Error: (ZIGBEE) 0x9035eafffeb5e390: can not process numeric item "co2" 2021-11-10 18:28:45.230 Error: (ZIGBEE) 0x9035eafffeb5e390: can not process numeric item "voc" 2021-11-10 18:28:45.230 Error: (ZIGBEE) 0x9035eafffeb5e390: can not process numeric item "formaldehyd" 2021-11-10 18:31:03.468 Error: (ZIGBEE) 0x9035eafffeb5e390: can not process numeric item "co2" 2021-11-10 18:31:03.469 Error: (ZIGBEE) 0x9035eafffeb5e390: can not process numeric item "voc" 2021-11-10 18:31:03.469 Error: (ZIGBEE) 0x9035eafffeb5e390: can not process numeric item "formaldehyd" 2021-11-10 18:31:03.672 Error: (ZIGBEE) 0x9035eafffeb5e390: can not process numeric item "co2" 2021-11-10 18:31:03.673 Error: (ZIGBEE) 0x9035eafffeb5e390: can not process numeric item "voc" 2021-11-10 18:31:03.673 Error: (ZIGBEE) 0x9035eafffeb5e390: can not process numeric item "formaldehyd" 2021-11-10 18:31:04.691 Error: (ZIGBEE) 'onMessage' failed 'KeyError'. 2021-11-10 18:31:04.691 Error: (ZIGBEE) ----> Line 297 in '/home/pi/domoticz/plugins/zigbee2mqtt/plugin.py' 2021-11-10 18:31:04.691 Error: (ZIGBEE) ----> Line 137 in '/home/pi/domoticz/plugins/zigbee2mqtt/plugin.py' 2021-11-10 18:31:04.691 Error: (ZIGBEE) ----> Line 167 in '/home/pi/domoticz/plugins/zigbee2mqtt/mqtt.py' 2021-11-10 18:31:04.691 Error: (ZIGBEE) ----> Line 217 in '/home/pi/domoticz/plugins/zigbee2mqtt/plugin.py' 2021-11-10 18:31:04.691 Error: (ZIGBEE) ----> Line 63 in '/home/pi/domoticz/plugins/zigbee2mqtt/devices_manager.py' 2021-11-10 18:31:04.691 Error: (ZIGBEE) ----> Line 64 in '/home/pi/domoticz/plugins/zigbee2mqtt/adapters/base_adapter.py' 2021-11-10 18:31:04.691 Error: (ZIGBEE) ----> Line 132 in '/home/pi/domoticz/plugins/zigbee2mqtt/devices/device.py' 2021-11-10 18:31:04.691 Error: (ZIGBEE) ----> Line 111 in '/home/pi/domoticz/plugins/zigbee2mqtt/devices/device.py' 2021-11-10 18:31:04.691 Error: (ZIGBEE) ----> Line 45 in '/home/pi/domoticz/plugins/zigbee2mqtt/devices/temperature_humidity_sensor.py' 2021-11-10 18:31:04.691 Error: (ZIGBEE) ----> Line 32 in '/home/pi/domoticz/plugins/zigbee2mqtt/devices/temperature_humidity_sensor.py'

This is the device in the zigbee2mqtt.io page

Do you have a link for this device on aliexpress or another place where I can buy it?

[daserra23]

There are many versions of it if you search for Tuya Air quality sensor.

[stas-demydiuk]

Got it, was confused that it looks different than the one by the link you've initially shared. Ordered one

[daserra23]

Wow, that's great. It does look different but in the zigbee2mqtt "front end" the device page shows the older (1st link) photo. It's a lot of sensor for not much money !

[stas-demydiuk]

@daserra23, now all features should be supported

[daserra23]

Brilliant. I gave it a try but as I am on an old Domoticz version due to OZW issues I fell foul of the exdomoticz situation and the plugin wouldn't work. However I will be upgrading Domoticz as soon as I have time to deal with my 35 Z-wave nodes with the next stable. Thanks a ton for your help; how did you find the Tuya hardware, I noticed it was a bit spammy but it didn't cause any network slowdowns ?

Hi,

I had also noticed that there were frequent updates, so in the WebGUI (frontend) of Zigbee2MQTT, I have updated the reporting settings so I only get an update every 60 sec

I did noticed that this device sometimes reports an extreme high value and then jumps to 0, and after some hours it starts to report again. So I have my doubts about the reliability of this device.

But it works fine with the latest plugin version, both voc and switch are as expected.

[daserra23]

Regarding the reliability, I noticed it will only give consistent readings if powered on in a "fresh" room, after which you close the windows, as explained in the meagre instructions.

Thanks for the tip about how to reduce the spamming.
