I just threw out most of my freezer. Apparently it hasn't been shut right for a week. I know "in the freezer" options are a problem because it's a metal box. Looking for a monitoring solution with a thermometer on a cable. Preferably ZWave but Wi-Fi would be ok. Powered or battery is an option, I've got a plug nearby. Could even wire to Ethernet for PoE if there's a good model that does that. Only thing I don't want is matter.

Bottom line, I need to find out the dang door is open before meat juice and ice cream runs all out on the floor.

What are my options?
