Presence Detection for openHAB via Wifi and Geofences

Many home automation task have to be done depending on whether somebody is at home or not. Heating the bathroom up in the morning is a good thing while somebody is at home but should be avoided while we are on a long vacation.

Furthermore, if openHAB knowns that somebody leaves home, it can take care of energy saving actions such as reducing the temperature or switching all lights off.

Home Automation with openHAB – My Setup

openHAB is a great open source solution to home automation. It allows to integrate literally any connected device from any vendor and therefore enables all kinds of devices to speak to each other through the HAB (home automation bus).

openHAB and Me

Many years ago, I started with home automation as a hobby using FHEM. At a fist glance, FHEM seems a lot simpler than openHAB but is also way more limited. As the number of home automation systems grow (Intertechno, Philips HUE, MAX!), FHEM wasn’t enough and so I started to try out openHAB.
