TIL: You can view long term statistics for sensors in Home Assistant
I had already tweaked my Recorder storage from the default of 10 days to 30, but was looking to view statistics for longer (e.g. a year). Maybe this is common knowledge, but I've use HA quite a while, and today I learned that many integrations have sensors that are already setup to store long term statistics for an indefinite amount of time.
Confusingly, these stats aren't shown anywhere in the default UI (as far as I can tell). Whether you go to the Entity properties, or the History page, neither shows these long term stats (just the shorter, Recorder ones). The only out-of-the-box way to view them seems to be with the "statistics graph" card.
