I am violating the “if it ain’t broke, don’t fix it” rule and moving my sprinkler controls from Node Red to Home Assistant.
(I break that rule often). I have the functions mostly finished and learned a bit about automations, scripts and helper entities along the way. (Not that that means I won’t continue to ask stupid questions in the future).
But, I have run into a wall. My town requires that my lawn irrigation can only be run on even-numbered days.
So, how can I run my sprinkler script only on even-number days?
