I started to play with Z-Wave at home lately. I found an inexpensive Raspberry Pi Hat for that purpose which is simply called the RaZberry. It’s compatible with all the raspi models so far and it comes with the complete Z-Wave stack and exposes a WebUI + APIs to the user. The main issue that I encountered was the range of the antenna, I had a lots of problems to reach devices that were few meters away from the controller just separated by a thin wall, and I hadn’t had any other devices working in that frequency range that could mess with it.
Ok we only have 5 minutes so: Host A: 10.0.0.1/24 Host B: 10.0.1.1/24 Those hosts are behind multiple routers but the are reachable, and there is no firewall between them. We will create a VXLAN tunnel between those hosts to put them on the same network segment, like if we had a dedicated VLAN connecting the hosts. host A: ip link add vtep100 type vxlan id 100 dev br100 local 10.
I wanted to tweak the way a daemon started on my system. I did that using its systemd unit file /lib/systemd/system/mydaemon.service. Everything worked fine until an upgrade remove my modification.

I use a custom ambilight-like on my media-center to display shinny colors on my walls. Boblightd is the daemon that connects to the ambilight appliance and opens a socket on the loopback interface of your media-center. Kodi, then has a plugin that connects to this socket and sends commands through it to the ambilight appliance. First we’ll have to install few dependencies: $ sudo apt-get update $ sudo apt-get install build-essential subversion portaudio19-dev libusb-1.
