Hey there @tuya, @zlinoliver, @frenck, mind taking a look at this issue as it has been labeled with an integration (tuya) you are listed as a code owner for? Thanks! _{^{(message by CodeOwnersMention)}}

I've got a similar issue. Instead of opening a new case, I'll ride along with this one.

Everything is working fine for Tuya cloud to home assistant integration. I finally got around to checking why my dehumidifer was not working. In Tuya cloud it's labeled as a KT device not a CS

I cannot control in home assistant

That sounds like bad idea, as it is not related.

@joz1n This issue might actually have been solved in Home Assistant Core 2022.10.4, could you try?

[joz1n]

Works fine now But sensor data is still not displayed And there is no fan and mode control Are they supported?

[frenck]

But sensor data is still not displayed

Looking at the diagnostics you've provided, the Tuya Cloud API doesn't provide sensors for your device. Thus it is correct you don't see sensors in Home Assistant either.

And there is no fan and mode control Are they supported?

Humidifiers in Home Assistant have no fan modes.

This issue is likely related to (or a duplicate of) #70016, #70344.

I too am unable to change the dehumidify_set_value Tuya attribute from within HA. Additionally, I'm seeing humidity_indoor available inside the data.status portion of the debug file, but no sensor for its value is created within HA.

My debug file: tuya-d49947b15c00c159b7c573724e28bac1-Twig Dehumidifier 1-cd7f17187279fd7a44073cac6387e015.json.txt

    "status": {
      "switch": true,
      "mode": "drying",
      "humidity_indoor": 58,
      "dehumidify_set_value": 50,
      "anion": false,
      "fan_speed_enum": "low",
      "child_lock": false,
      "swing": true
    }

The status documentation for Dehumidifier (cs) lists "countdown_left", "pm25", "temp_indoor", "humidity_indoor" as possible sensor values. Both temp_indoor and humidity_indoor seem to be missing from tuya/const.py.

Does "%" need to be added to the PERCENTAGE UnitOfMeasurement aliases?

I changed my dehumidifier to climate entity (and also created sensors for humidity and temperature). It looks much better now.

The biggest plus with climate entity is, you can control tuyas fan_speed_enum. This isn't possible with home assistants (de)humidifier.

The down sites are, the climate card is broken and you don't have a history because these are only for temperature. But when someone need these things, you can workaround this with dehumidifier template I think.

I would make a pr, do you like the climate solution with fan support or should I just fix the current dehumidifier?

[Andre0512]

I overthought it and I think the cleanest solution should be here to stay with the dehumidifier entity and create some sensors and controls.

Note: My dehumidifier has the dehumidify_set_enum here (see tuya docs), so you can only chose between some given values. If your dehumidifiers have dehumidify_set_value, you can control it with the humidity control, else the "Target Humidity" select will be created.
