OpenHAB supports a lot of different "bindings", i.e., Hardware and Protocol solutions implemented by different companies. I started my home automation project with the Homematic binding. There are two tutorials I follow (german only):
- Setup of Homematic binding in OpenHAB2
- Implement a heating control
The first one was really easy to follow and worked straight away. I had to restart the OpenHAB service, though, which wasn't mentioned in the documentation.
For the second tutorial I ordered the window sensor and the heating control as mentioned in the tutorial. They haven't arrived yet, so I will post again when they arrive.
I am currently looking into openHAB for a possible solution for our home automation. I do have an unused laptop that could easily be used for this.
What I would like to have control over:
- room temperature
- some lights
- smoke detectors
There are different devices manufactured by different companies for each of the above. So its a question of finding the best hardware.
All of this needs to be accessible via an app on my phone.
- notifications for alarms (smoke detectors)
- control stuff
Seems like all of the above is provided by openHAB combined with a VPN solution, which is great!
Updates on the selected hardware and the integration will be given here in the future, stay tuned!
I recently bought an e-paper display with a 2.7" screen size distributed by Embedded Artists. Since it does not consume any power between updates it is perfect to display status information for any kind of embedded technology. Since I am quite the Arduino fan my plan was to hook it up to one of them and simply use an existing software library to interface it. (Update available)(second Update)

for my first post that actually contains content, I would like to show you what I use as a cheap and small GPS device.
GPS devices can be found in a lot of different devices, like mobile phones, cars and security devices. One class of such security devices are GPS -Tracker. GPS-Tracker constantly register their position and send the information to a previously specified user via eMail or SMS. I bought this tracker (for ~60€) that sends a SMS with the current position as a reply to a request SMS coming from me. The initial idea was to get the position of a RC plane in case its lost or to track the position of my cat 🙂
