[tuya] No functions are available for Bluetooth TRV of model SEA802 B01 (Bluetooth TRV (drlajpqc))

[forabi]

The problem

There's pretty much no functionality available to control any function of this Bluetooth TRV via Tuya integration

Basic missing features include: seeing current temperature, setting target temperature, setting mode to "Away".

One commercially available product using this module: Maxcio Smart Heating Thermostat Compatible with Alexa & Google Assistant, WiFi Gateway and 2.4 GHz WiFi Required, WLAN Radiator Thermostat with Child Lock Function

Example YAML snippet

No response

Anything in the logs that might be useful for us?

Many properties in the JSON diagnostics file are `null`, including `current_temperature`. Also, the `state` is `heat_cool` but the device only supports `heat`. There's also no target temperature as far as I can tell.

Additionally, `supported_features` is `0`, which probably means the features are not detected?

Additional information

Using Tuya CLI, I can get the following information for the same device:

base ❯ tuya-cli get --id xxxxxxxxxxxxxxxx --key xxxxxxxxxxxxxxxx --cid xxxxxxxxxxxxxxxx --full
{
  dps: {
    '8': true,
    '10': true,
    '27': 0,
    '40': true,
    '101': true,
    '102': 203,
    '103': 50,
    '105': 0,
    '106': false,
    '108': true,
    '130': true
  },
  cid: 'xxxxxxxxxxxxxxxx'
}

Using Tuya API Explorer, these map to the following:

It seems like the most important properties are:

• 101 - Switch
• 102 - Current temp
• 103 - Target temp
• 106 - Away mode (pauses the TRV)

Additional functions that are exposed in the app and also have matching properties in the JSON response above:

• Antifreeze on/off
• Window open detection on/off
• Water scale proof on/off
• Temperature calibration (how many degrees to adjust the current temperature -- useful for large rooms where the thermostat's measure temperature is warmer than that of the other side of the room)

Screenshot for the same device from the app:
