Atlantic
Atlantic builds the heat pumps, water heaters, radiators, towel rails, and ventilation that its Cozytouch app controls. Cozytouch runs on the Overkiz platform, the same platform behind Somfy TaHoma, so Home Assistant reaches an Atlantic install through the Overkiz integration with Atlantic Cozytouch selected as the server. What sits between the appliances and that account varies by vintage: a Bridge Cozytouch talking io-homecontrol on older ranges, a CozyBox on current radiators and towel rails, and nothing at all on the appliances that joined Wi-Fi themselves.

2 devicesBridge Cozytouch
The Bridge Cozytouch is the gateway behind most of the installed Atlantic base: it joins the home network and speaks io-homecontrol to the heat pumps, water heaters, radiators, and ventilation. Home Assistant reads it through the Overkiz integration with Atlantic Cozytouch as the server, over the cloud only. Atlantic has since moved current radiators and towel rails to CozyBox, so the bridge is now a device to support rather than to specify.
Pass Cozytouch
The Pass Cozytouch (602251) is the io-homecontrol radio interface that retrofits an Atlantic appliance with no radio of its own. It mounts behind the unit and lets the Bridge Cozytouch, and therefore Home Assistant, see it.
