This same exact thing started happening to me a few weeks back.
I have an Almond+, and a couple of peanuts I use as my morning wake up routine / alarm (few house lights turning on, TV turning on to act as my alarm clock). I have had this same routine with the same peanuts working flawlessly for a few years now. Then, all of a sudden a few days out of the week nothing wakes up in the morning (including myself). Oops. I’ve check my router logs and the times are normal, just the rule didn’t engage?
