After setting up OpenWeatherMap in openHAB, I had another project on my list: send a forecast for the next day.
That is rather easy to do with a Cron rule.

Next item on my home automation todo list: weather, and forecast. No good system without that data!
After exploring the options which openHAB supports, I settled for OpenWeatherMap. Note: you need an account with OWM, the basic functionality is free, the paid options give you more and better forecast.
And of course, I install everything using Ansible, and can just repeat the entire installation if something does not work.
This setup is also used in a weather forecast for tomorrow.

You might know that problem: the brand new SSD in your system is super fast, but after a good time using it, the card is dead. Unlike spinning disks, which usually fail over time, and show I/O errors by blocks, SSD cards are prone to a problem called "Wear leveling". Blocks which are written more often will "wear out", and become unresponsible. More writes increase this risk. And a typical openHAB system does a number of writes all the time: every time an external status changes, it's written to the event log. By default the syslog is written to disk as well, and then there is a myriad of systemd services, writing status information into files.
