Is it possible to get interface or API to my Vaillant ECO-tec condensing boiler ?

Thanks to our knowledge at this particular lines of boilers we are able to communicate through  Programmable Room Thermostat with Weather Compensation.


We have successfully tested on:

  • Vaillant VRC calorMATIC  470
  • Vaillant VRC calorMATIC 430..

We need 2-wire connection from raspberry to your calorMATIC



We have used API connection to the boiler as a baypassing proxy between Calormatic and eco-tec boiler.
