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:
- ESP32/ESP8266 module
- Master OpenTherm Shield
- DS18B20 digital temperature sensor
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.
