External integration - Saunier Duval (Vaillant) boilers

Hello,

I just started Claude on developing an integration to read and control my boiler.

The features supported so far:

  • Room temperature and humidity (thermostat)
  • Outdoor temperature
  • Burner status
  • Water pressure
  • Boiler switch (to configure for default operation: in program mode or manual when on « On »)
  • Setpoint temperature (read and input)

Looking forward to your feedback! (it shouldn’t be long before it hits the store)

(thanks @pierre-gilles for this new evolution of Gladys, we can feel a strong acceleration)

Hello,

With the experience gained from using Claude for developing integrations, I decided to start from scratch on this one. The integration was removed from the store on 10/08/2026 in the afternoon.

Also, any installation of this integration made from the store before 11/08 must be uninstalled to allow the implementation of the new nomenclature, which enables the following breakdown:

  • Boiler
  • Heating circuit (usually 1 in an individual home)
  • Thermostat (as many as you have, zone management)
  • Domestic hot water

The new implementation is available on GitHub, still under testing. It’s coming along well; I aim for a new release on 11/08/2026.

Thank you for your understanding.
