# eQ-3 Bluetooth Smart Thermostats

> eQ-3 Bluetooth Smart Thermostats is a built-in integration for Home Assistant. It has 222 installs sharing analytics and works locally.

eQ-3 Bluetooth Smart Thermostats is a built-in integration that controls eQ-3 radiator thermostats over Bluetooth. It communicates locally and is added through the interface, using the device's MAC address. Each thermostat appears as a climate device, with switches for away, boost and lock modes. Number settings cover comfort, eco, offset and window open temperatures, plus the window open timeout. Sensors report the valve state and the away until time, and a binary sensor shows daylight saving time. Home Assistant can also discover compatible devices on the network and offer to add them.
