About

Philips Heater is an integration that controls Philips CX3120 and CX5120 heaters locally over CoAP. It talks to the heater on the local network, so neither the Philips cloud service nor the mobile app is needed. It adds a climate entity with Off, Heat, Auto and Fan Only modes, presets for Low, High, Auto, Auto+ and Fan, target temperature, and oscillation control. Sensors report room temperature, heating intensity, operating mode and target temperature, plus diagnostic IP and MAC addresses. Two settings stand out: a default heat preset for systems that only send heat or off, such as Matterbridge, and an Auto+ offset of 1 to 10 degrees above room temperature. Heaters are found automatically on the network, or can be added by IP or MAC address in the UI.
