Sauter
Sauter is the third Groupe Atlantic heating brand on the Cozytouch platform, alongside Atlantic and Thermor, with radiators, towel rails, water heaters, and ventilation. Cozytouch is built on Overkiz, so Home Assistant connects through the Overkiz integration with Sauter Cozytouch selected as the server, with a Bridge Cozytouch on the home network carrying io-homecontrol to the appliances that need one.
Hardware availability
Sauter Cozytouch is cloud only, with no local API path in Home Assistant. The bridge hardware is the same across Atlantic, Thermor, and Sauter, but the account and the server selected in Home Assistant are per brand, so a home mixing brands needs the bridge that matches the appliances. The gateway is also generational: Groupe Atlantic is moving current ranges onto CozyBox, and Wi-Fi appliances register without any gateway, so a Sauter install can be on any of the three. Some Cozytouch appliances are not supported by the Overkiz platform, which is a per-model check rather than a brand-wide one.
