Dear Sir,

Thanks for sharing your project. It is very interesting.

I expose my issue:

My solar inverter closes a relay when reaching some photovoltaic sun irradiance parameters.
I want to turn on the Intex spa heater when that relay is closed to derive photovoltaic power excedents to heat the spa.

My problem is that the inverter is 12 meters away from the spa and I don't have wired cable from one to another.
My first idea was to pair 2 arduino using RF 433 Mhz (one in each side) and modify your code in the arduino that controls the ESP8266 in order to turn on heater when the first arduino detects solar inverter relay closed.

However, I wonder if a simpler solution using MQQT or Home Assistant is possible.

Any help is much apreciated.

Thank you very much in advance
Kind regards from Spain
