I use it to turn on/off a/c window unit when temperature reaches a certain temperature. Also got another for another room that opens/close curtains at a certain temperature during a specific time period. Works great 👍.
It works great, I’ve got one outside and one in my chicken coop, with a glance at the app I know what the outside temperature is but also what the temperature is in the chicken coop and if I need to add another Heat lamp to warm it up in there for them
