Unknown mystery device

Ive got an unknown device that goes on for 10 seconds, then off every hour, usually to the minute. It draws 38-40 watts. I thought it might be an air purifier sampling the air but ruled that out. Occasionally, there may be a several hour period of no activity, but that is the exception.

I forget the wattage, but I ended up identifying similar behavior as an icemaker. It was regular about dumping the ice, and would occasionally go quiet if we didn’t use any ice for a period of time.
