Integrate Beca Modbus thermostat with Nest like UI
I am integrating a Beca Modbus Thermostat with Node-Red using the Nest like dashboard control. This flow shows how you can read and write the registers to create a 2 way communication between Node-Red and the modbus thermostat. In this flow, I am also using a Nest like UI widget as the temperature display.
You can see a video on this flow here: https://youtu.be/z2HaGW_dKdU
