Tried setting up this device and configuring an external converter but haven’t gotten anything working.

External converter

Nothing usable…

I was trying to setup a converter to make this report the same as another very similar device that I already have and that is supported: _TZE200_dwcarsat - the TuYa TS0601_smart_air_house_keeper

I've tried setting up something like below but it hasn't worked:

convert: (model, msg, publish, options, meta) => {
    const dpValue = tuya.firstDpValue(msg, meta, 'tuya_air_quality');
    const dp = dpValue.dp;
    const value = tuya.getDataValue(dpValue);
    switch (dp) {
    case tuya.dataPoints.tuyaSabTemp:
        return {temperature: calibrateAndPrecisionRoundOptions(value / 10, options, 'temperature')};
    case tuya.dataPoints.tuyaSabHumidity:
        return {humidity: calibrateAndPrecisionRoundOptions(value / 10, options, 'humidity')};
        // DP22: Smart Air Box: Formaldehyd, Smart Air Housekeeper: co2
    case tuya.dataPoints.tuyaSabFormaldehyd:
        if (['_TZE200_mja3fuja'].includes(meta.device.manufacturerName)) {
            return {co2: calibrateAndPrecisionRoundOptions(value, options, 'co2')};
        } else {
            return {formaldehyd: calibrateAndPrecisionRoundOptions(value, options, 'formaldehyd')};
        }
        // DP2: Smart Air Box: co2, Smart Air Housekeeper: MP25
    case tuya.dataPoints.tuyaSabCO2:
        if (meta.device.manufacturerName === '_TZE200_mja3fuja') {
            // Ignore: https://github.com/Koenkk/zigbee2mqtt/issues/11033#issuecomment-1109808552
            if (value === 0xaaac || value === 0xaaab) return;
            return {pm25: calibrateAndPrecisionRoundOptions(value, options, 'pm25')};

Supported color modes

No response

Color temperature range

No response

This device seems to be identical to _TZE200_dwcarsat

I have still been unsuccessful trying to get _TZE200_mja3fuja to mimic function of _TZE200_dwcarsat

[Charliedean]

Also having this issue. @jmluxem did you mange to fix this?

[oedo808]

Me too! First zigbee device joined but no expected entities :-)

[jmluxem]

I have not been able to fix this. Haven't had much free time to devote. Was hoping @Koenkk might be able to sprinkle some of his magic, since I don't believe any real datapoint-finding is required - I'd bet that a direct conversion from _TZE200_dwcarsat would allow this to function, but making that work properly escapes me. The unsupported device is _TZE200_mja3fuja, but I bought it thinking that it was identical to _TZE200_dwcarsat - they both have the same functions. I may be wrong but I don't exactly have the knowledge/time/hardware to test my belief.

[Koenkk]

Could you check if the issue is fixed with the following external converter: https://gist.github.com/Koenkk/002a6a797922f736db47fd4bb2f5f19c

• save this as file next to configuration.yaml as ext_converter.js
• add it to configuration.yaml:

external_converters:
  - ext_converter.js

• start z2m, check if issue is fixed

[jmluxem]

Heck yeah, that's why you're the boss :)
That converter got temperature and humidity reporting correctly - confirmed by breathing into the sensor.
CO2, VOC, and Formaldehyde are reporting values, but tough for me to confirm validity/correctness since it seems the sensor updates those at a much slower rate, and it may not be very accurate to boot. PM25 not reporting any value currently.
Regardless, this is leagues better than anything I had gotten working. Thank you!

State values:
{
"humidity": 43,
"linkquality": 163,
"temperature": 28.3,
"co2": 13,
"formaldehyd": 514,
"pm25": null,
"voc": 72
}

Please let me know if there are any other logs or items I can pull for your benefit.

[Koenkk]

Can you try the following, in your data/database.db change the manufacturer name from _TZE200_mja3fuja to _TZE200_dwcarsat and see if everything works now? (no external converter needed)

[jmluxem]

I run HAOS with z2m as an addon. I am not seeing a 'data' directory. In my file structure, I have config/zigbee2mqtt/database.db

Within that database.db file, I changed the name to _TZE200_dwcarsat and restarted z2m, but it doesn't appear to be keeping the change - when i go back to the database.db file, the old _TZE200_mja3fuja name is back where I had just changed it.

[Koenkk]

You need to stop z2m, make the change and start z2m.

[jmluxem]

Thank you for that tip/correction. I updated the database.db file and now the device is working without the converter. Everything appears to be working

[Koenkk]

Great, integrated the changes!

Changes will be available in the dev branch in a few hours from now. (https://www.zigbee2mqtt.io/advanced/more/switch-to-dev-branch.html)
