Bro, I hate to say this but sometimes things that aren’t connected to the internet also need firmware updates!
My server room’s AC has a bug where it won’t start cooling if the room temp goes too far below the set-point of the AC and then goes back up above the set point again. Its a repeatable bug (reboot it fixes the setpoint, turn down the AC until it activates ALSO fixes the setpoint.)
I’d do something other than complain about this on tumblr if I could update! the! firmware!
update: my AC apparently DOES have the ability to connect to the internet over wifi
Home Assistant integration is not a rabbit hole i wanna go down right now
