openhab2: check if alive

As mentioned in my previous openHAB blog post: it seems to be too much to ask to have a reliable and working display in the kitchen.

Another problem I found is that the weather data occasionally does not update. Everything seems to work, no errors in the log, just no updated data. Of course this results in outdated weather info in the kitchen, and the threat that “someone” will buy a regular weather station and render my 7" Raspberry display useless.

In our Home Automation system, I read weather data from OpenWeatherMap. I blogged about the implementation before. The weather data provides an icon which can be used to show the current weather:

Weather Forecast in openHAB based on OpenWeatherMap, using Ansible

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.
