iHOST controlling TUYA WIFI Thermostat via Virtual Thermostat and Alexa

Hi everyone,

I want to share my Node-RED flow running on Sonoff iHost. It creates a Virtual Thermostat on eWeLink CUBE and syncs it with a real Tuya/SmartLife local thermostat (BHT-002 / BHT-8000 family, “wk” category).

This flow specifically fixes two common issues:

  1. It bypasses the Tuya restriction where target setpoints are ignored unless the device is actively forced into Manual Mode (DP 4 = “1”).
  2. It includes an eco-filter to stop command loops/reflections generated by Alexa/Matter integrations.

Note: You will need to re-enter your own Tuya deviceId and deviceKey inside the real thermostat node after importing.

Here is the JSON flow:

I hope that can help someone… Enjoy.
