Review on X Sense Interconnected Transmission Battery Operated XS01 WR by Daniel Greene

I bought 3 packs of these for Christmas 2020. I installed one in my garage, left one in the shed and the third at home to keep an eye on the temperature. other 2. At 5:30 everyone started screaming. There is no fire in the house, garage or barn. The only thing I can think of is that the cold night temperature in the barn has either reduced battery life or something else is wrong. I was happy with my purchase until this morning. Stupid easy installation. The connection worked perfectly, as all 3 prove.
