Perhaps I will share some posts on how to get that working or how it turns out to work (or not).

Or even build my own MQTT gateway using the Open ZWave library. I will do some experimenting on this first before deciding to use Domoticz or perhaps some other Open ZWave implementation. Since all of my domotica uses MQTT for communication I might use the MQTT possibilities of Domoticz too. I am thinking about using Domoticz for its integrated Open ZWave library support to control my ZWave network. But since I already have a Gen-2 let’s use that to start with. With the Aeon Labs Z-Stick, all I had to do was take out the usb stick, walk to the item I wanted to pair, push the button on the stick and then push the button on the item I wanted to pair. Time to associate the new dimmable switch. If this works the way I hope I perhaps might migrate to a gen-5 Z-Stick as well. Start with the mandatory reboot (even though we are on linux) and what do you know, I now have a http server instance at port 8083 just as promised. It seems that the Z-Stick solution is much more stable. So I have decided to move away from the Razberry and use the Aeon Labs Z-Stick (gen-2) on a new PI 3. Home-assistant needs Python 3.4, so the first thing you have to do is make sure your Raspberry Pi 2 has at a Raspbian OS based on Debian Jessie on it. package: 1x Z-Stick Gen5, 1x Manual, the others are not included. Tiny but powerful 1.1 x 0.4 x 3.5 inches in size and capable of controlling up to 232 different Z-Wave devices. Also the API to the Razberry has changed several times which forces me to change my software as well or to keep working with an older no longer supported API. Raspberry Pi 2, home-assistant, and the Aeon Z-Stick. Works with Windows / Mac / Linux (including Raspberry Pi) to create a Z-Wave gateway for control of Z-Wave and Z-Wave Plus devices. After having used the Razberry on the Raspberry PI for quite some time now, I am growing tired of having to power cycle the PI every month of so because the Razberry stops working.
