My folks spend the winters in Arizona. They have a person who checks in on their house from time to time but they are worried about the freezer, if it were to give out, odds are that all their meat would have thawed by the time it was noticed.
Are there any devices that could sense a freezer failure and trigger an alarm (such as a flashing light in the window where a neighbor could notice it, or a very loud audible alarm?) I’m not so much worried about a power outage, as the neighbor would be aware and could take care of it. I’m primarily concerned that this old freezer will give up.
Such a thing may be pretty far-fetched but I thought it was worth asking. Surely I’m not the first person to have thought of such a thing.
