I really wish that my heat pump remote control/machine wouldn't make a beeping sound and then do nothing sometimes.
I don't know if I'm not pressing the button long enough or whatever, but I'll hear a beep, 10 min later I'm still freezing, turns out I never turned it on.
Or I'll come back in an hour and I never turned it off.
@Satsuma and I even have decent (annoying) audio sensitivity. But I don't use it that much and they're so similar.
