RaspMatic + HomeMatic (IP)

Some time ago I bought a Raspberry Pi 3B with the RPI-RF-MOD extension module and the corresponding case. It’s also possible to buy all in a set: Buy link (I am not affiliated). There is an image available that works like a charm for this setup, whcih can be found here. Multiple models are supported, so make sure you download the correct release.

I am very happy with this setup. HomeMatic provides a multitude of different devices ranging from simple sensors (temperature, light, …) to quite sophisticated weather stations. There are also actuators available for heating control, blinds/shutters to alarm sirens. What is even more interetting is that general relays and comunication modules are available, so you can also build your own smart home devices!

First Installation of OpenHAB2 and Homematic CCU2

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):

  1. Setup of Homematic binding in OpenHAB2
  2. 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.

Home automation

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
  • shutters
  • 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!
