Hello,

Could you give me some pointers to support the Tuya HY02B05-WIFI Thermostat?
It has an esp based TYWE3S but a PIC16F1947 chip as MCU. Since only VCC,GND, GPI15, RX and TX are connected, most functions will certainly be perfomed by the MCU.
As I understand, Tuya has some standard way of interfacing with the serial, so I assume this will also be the case?

Any pointers in how you solved the support for your existing devices so I can have a jumpstart at supporting this thermostat ?

Thanks,

Yves

OK I now flashed tasmota, saves much time to find out the protocol.

This is what I now gathered:

I guess I'll have to press some buttons and see what changes now, document it and maybe add it to WThermostat ?

After some testing:

DpId 1: Boolean, Switches the device on or off, display clears, I hear the relay clicking when it's heating, same as power button
DpId 2: Integer, target temperature x 10 so 240 is 24.0 degrees C
DpId 3: Current measured temperature x 10, so 215 is 21.5 degrees C
DpId 4: Enum,
0 = Manual,
1 = Auto,
2 = Bag icon: Holiday mode,
3 = Manual override I think, when updating DpId2, this switches to 3
4 = Disabled I think (no state icon displayed)
5 = Disabled I think (no state icon displayed)
DpId 6: Boolean, Display lock
DpId 101: Boolean, function unknown, (toggling doesn't update the value)
DpId 102: Boolean, Heating relay state, (toggling doesn't update the value)
DpId 103: Integer, function unknown
DpId 104: Integer, function unknown
DpId 105: Integer, function unknown
DpId 106: Boolean, function unknown
DpId 107: Boolean, function unknown
DpId 108: Boolean, function unknown, (toggling doesn't update the value)
DpId 109: Integer, function unknown
DpId 110: Integer, function unknown
DpId 111: Integer, function unknown
DpId 112: Integer, function unknown
DpId 113: Integer, function unknown
DpId 114: Integer, function unknown
DpId 115: Integer, function unknown
DpId 116: Enum, function unknown
DpId 117: Enum, function unknown
DpId 118: Enum, function unknown

Hi, please select HY08WE as model for your thermostat. Following commands fits already to your model Target/Measured temperature and display lock. There should be some unknown MCU messages reported to your mqtt broker. Please report this.

Check binary WThermostat_1.20b_alpha, I added support for schedules mode (DpId 4). Should be Manual, Auto, Holiday, Hold (acc. to manual: hold temp for 1 h, and then switch back to auto?). Please check

I now updated the firmware to 1.20l_beta. I still need to add it to MQTT to see if it's functional on that side, but so far it looks good.

I don't have any mqtt topic in '#' that shows me the current temp, nor the set temp.
