Online indicator for remote controllable power plugs in openHAB

Recently I installed a number of new power sockets. The Hue bridge can not only add each switch to a light group, but also reports each plug as a Thing in openHAB. There I thought it will be a nice touch if openHAB actually reports when it sees a device plugged in. The power socket has a LED which turns on when the plug is on. The Hue bridge reports 'OFFLINE' and 'ONLINE'. That's useful. The plan is to turn the LED light - and the power plug - on and off for a few second.

Install openHABian image on Linux

My plan is to reinstall openHABian on a bigger SDcard, and on a Raspberry Pi 4. The latest release (v1.5) supports the new Pi 4, and I decided it’s time to do a fresh install, and see if all my Playbooks are still working.

As always, I’m searching my shell history for the right command how to install the image … but came up empty.


Add a FRITZ!Box to openHAB, using Ansible

Next step on my way to add home automation: the FRITZ!Box. Mostly for the current IP-address, and call information.

After some research it became obvious that more manual work is required, hence again something which can be automated.


Install openHAB2 bindings using Ansible

Recently I started looking into Home Automation, using a Raspberry Pi and the openHAB as platform. The website provides ready-to-go images based on Debian, named openHABian. Me being me, I decided to install the image, let it boot up for the first time, and then take it from there using Ansible as automation tool. That’s a bit more effort in the beginning, but ensures that I can always just wipe the SDcard, and start over from the beginning. Especially useful if I screw up at some point during testing.
