In the following tutorial we show how to create programs for the eQ-3 Homematic Window Sensor to transmit the state of windows and doors to a display, for example by means of system variables. You can also link Window Sensor directly to the Homematic radiator thermostat to save heating costs in winter by automatically lowering the thermostat when the window is open and then raising the thermostat again. How this works, we show in the new Funkyhome.de Smarthome Tutorial.
