BHT-002-GBLW and external temperature sensor

Hello!

I’ve a MOES BHT-002-GBLW (Wifi version for electric floor heating).
I flashed it using this guide. All working good, but I need to use external temperature sensor instead of internal and I got some problems with that.

climate:
  - platform: tuya
    name: "Thermostat"
    switch_datapoint: 1
    target_temperature_datapoint: 2
    current_temperature_datapoint: 102
    preset:
      eco:
        datapoint: 5
        temperature: 20 °C
    temperature_multiplier: 0.5
    visual:
      min_temperature: 5 °C
      max_temperature: 35 °C
      temperature_step: 0.5 °C

I replaced current_temperature_datapoint from 3 to 102 in climate section and thermostat device in HA indicate right temperature of external sensor, but physically thermostat continue using internal sensor for working.

How I can fix it?
