I setup a multisensor in my kegerator to work as a thermostat in conjunction with the smart outlet. Everything worked perfectly for 3 days, until I noticed condensation pouring off the tower (a sign it is far colder than I configured it to be). I looked at the app and it said it was only 40F, and was powering the compressor non stop to try and get it down to the preset of 33F.
In reality it was closer to 28F in there, so I pulled it out and discovered condensation all over it, which I figured was screwing with it. I took the batteries out and blew it off with a hair dryer, and put them back in. It quickly readjusted and settled on room temperature like normal. To protect it against the condensation I covered the chip, and PCB in hot glue, leaving what I assume is the temperature probe bare (this red bar thing with a wire going in on each end) It was too big at this point to fit back in the enclosure so I put it naked back in the kegerator (with its hot glue shell)
But, this didn’t fix the issue. It quickly got done to 32F in the kegerator…but then did a steady climb back up to 40F…and is running the compressor non stop again. Anyone have any ideas?
here are some pictures of how I decided to void my warranty
