A while ago I integrated DWD warnings (Deutscher Wetterdienst) into our home automation system, and receive severe weather notifications ever since then. That works quite good, but it was missing a weblink with more details - or if you want to forward the warning to someone it would be useful to have a link to the warning as well.

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.
