Most of my automations are lighting-based, so my favorites are both simple in theory but I can’t imagine going without them:
1.) When I get home (or near home) and it’s after dark, the living room lights and the TV turn on.
2.) Not really an automation on its own, but when I lay down to bed I turn off my bedroom lights through the HA app. I’m so used to it that the thought of turning the bedroom lights off at the switch then fumbling through the dark to bed sounds barbaric at this point.
Back on reddit there were those who had alerts set every time the word came up across the site, then they’d brigade the fitness and health subreddits with their vegan crew to derail any conversations. It was really annoying. No clue if that’s still a problem because lolreddit
