OpenTherm Thermostat

Hello Blynk Community!

I would like to present you simple OpenTherm thermostat example based on Blynk platform.
To build the thermostat you will need a few parts:

Boiler connection is very simple:

Then you will need to install such Arduino libraries:

  • install Blynk library
  • install Ihor Melnyk’s OpenTherm library
  • install DallasTemperature and OneWire library

Then flash thermostat sketch, you can pull it from diyless github

Then build similar or use shared Blynk thermostat application just by scanning QR-code from this blog post Blynk OpenTherm Thermostat

That is it.
