I just don’t see the utility. I can be pretty pro “smart” stuff, especially if I can run it without an internet connection, but what’s the point for a fridge?
About ten minutes ago I installed a smart bulb in my fridge. I plan to set up an automation in Home Assistant to tell me when the fridge has been open too long. I also have a temp sensor near the compressor because I had an issue with the fan going out and now if the temp is too high I get an alert to check on it.
I also have a temp sensor in the freezer and the main fridge, again to alert me when things go wrong.
