This is an example of Yet Another Watering Solution I’ve developed for my garden.
Background:
The goal was to make a complete, fully configurable irrigation system, with the ability to easily expand the number of the zones, overwatering protection and correlation with the weather.

once a minute check if we’ve just passed the hour a…
