Thermor
Thermor is the Groupe Atlantic brand for connected electric radiators, towel rails, heat pump water heaters, and ventilation. Its connected range runs on Cozytouch, an Overkiz platform, so Home Assistant reaches it through the Overkiz integration with Thermor Cozytouch selected as the server. Older appliances get there through a Bridge Cozytouch on the home network, talking io-homecontrol; current Wi-Fi appliances register themselves and need no bridge.
Hardware availability
Thermor Cozytouch is cloud only: Home Assistant’s local API covers Somfy and Rexel gateways, not the Cozytouch bridge. Two bridge generations are in the field, the original wired Bridge Cozytouch and the Wi-Fi Bridge 2 Cozytouch, and both appear the same way to Home Assistant. Groupe Atlantic is also moving current ranges off the bridge onto CozyBox and native Wi-Fi, so establish which of the three a house uses before pricing work. Which entities show up depends on the appliance rather than the gateway, so check the model against the Overkiz platform before promising a feature.
