Doesn’t work for washers and dryers that use sensors to tell when the clothes are clean/dry.

Thankfully, my set is “connected” in that you can connect to it to see status updates and adjust notification volume, but everything else is manual.

My fridge also has monitoring, and tells you if the inside temperature goes outside range. It also lets you toggle the ice maker, notify you when it’s full and adjust temperature of the three compartments. I can see that last one triggering something similar to Samsung’s gaffe if a firmware update hard locked the temperatures to negative values or something.
