Many users experienced an issue after a home assistant update some time ago relating to how default values were handled. There is a fairly simple fix posted a long way back in this thread, but I forked the blueprint and made the modification myself to save others the trouble. Over the subsequent months i’ve been progressively adding more features and fixes for edge cases.
There’s no need to change for anyone who doesn’t have issues with the one in the OP, but as hunterjm has not posted here in a while i’ve been supporting this updated version
