I have some plants that can’t handle freezing temperatures that I would like to be able to leave outside during the winter. I have some c9 christmas lights that put out a good deal of heat that i’ve heard of people using on a timer at night to prevent freeze damage.
I would like the option of having a temperature sensor turn on an outlet (with the connected lights) when the temperature goes below 40,50, etc (obviously I’d have to calibrate when it should turn on once the project is all assembled) but then again turn the outlet off if the temperature goes above 60 or 70ish to not waste energy, not damage my plants from heat.
I need a smart outlet (i already have some cheap ones but I’d be willing to get a new one) that is compatible with scenarios or IFTTT or something, as well as a decent temperature sensor (hopefully better than 2 degrees accuracy). It’s most important that both of these respond in a reasonable amount of time, I’ve had IFTTT scenarios take 30-1 hour to actually run and that won’t work for this. I’ve been thinking about the smart things platform at least as a hub even if the temperature sensors aren’t good (i’ve read a lot of older posts about them not being accurate but not as much on the newer sensors).
Any temperature sensors with this functionality y’all’d recommend? Anything you think I’m missing to make this project work? I’m all good on the plant end, I just need help with the device end!
