External integration - Heatzy

Hi everyone!

The Heatzy module is the very French way to control electric heaters, and Heatzy is one of the most widespread modules for doing so. Here is Heatzy for Gladys: the mode of each radiator, with the native Heatzy pilot selector of Gladys.

What it does

  • One device per module (Pilot v1 to v4, Pilot Pro, Glow, Onyx, Inea, Bloom): Comfort, Comfort -1 / -2, Eco, Frost Protection, Off modes, locking and programming according to the model, temperature and humidity read-only for those that have them.
  • A widget « Heatzy Radiators »: the mode of each radiator and four buttons (Off requires confirmation).
  • Triggers: mode changed outside of Gladys (app, programming, module button), module offline, module back online.
  • Actions: set a radiator or all to a mode, start or stop the vacation mode.

The cool thing

Alarm activated → all radiators in Eco, and Comfort on return
Window open → this radiator in Frost Protection
Module offline → message with the radiator name

Installation

Gladys 5.1 minimum.

It will arrive in the store at the next indexer run. In the meantime: Integrations → Install from GitHub, with the address GitHub - guim31/gladys-heatzy: Heatzy pilot-wire modules (comfort, eco, frost protection, off) for electric radiators in Gladys Assistant · GitHub

  1. Enter the email and password of your Heatzy account, then Test the connection.
  2. Add the modules from the Discovery tab.

An important choice: when you choose a mode from Gladys, the module’s programming is cut off (otherwise Off or Frost Protection would jump to the next slot). This is explained in the documentation.

Honest caveats: it goes through the Heatzy cloud (Internet required), reads the modules every 2 minutes by default, and was developed without a module or account, based on the real responses published by the hass-heatzy project. Settings and programming are always adjusted in the Heatzy app, and nothing is exposed as a thermostat to voice assistants.
