Good day, Im looking for the best way to make a tag that tells me is Day or Night based on a time range.
Example, if its between 8:00:00 and 20:00:00 then its Day, else its Night.
An expression tag, set to 'event driven', with an expression of:
timeBetween(now(1000), "8:00:00", "20:00:00")
I would expect to work, though you may need to tweak the format of the two time constants.
