Smart WiFi Reptile Thermostat Outlet Heating Cooling, Tuya Digital Temperature Controller Sensor Plug for Fermenter Brewing Breeding Heat Mat, Smart Life Remote Control, -22- 221℉,10A 1250W

Used two of them in greenhouse for two winters and one summer. One got broken. Bought a new one because got used to model. The switch on works always on both heaters and fans. But it does not always turn heaters and fans off when the limit temperature is reached and I have to do it manually to prevent overheating. For example, I set low at 67 and high at 82 thinking the heater will turns of after 67 and fan will be of at 82. But the heater may go up to 82 until fan is on and vice versa.

App is questionably a bit too foreign, but it works. I’ve used one to control my ac for a couple of years now still going strong.

I can say the quality of this product is great. It’s pretty responsive. it works with my Alexa app and dot. I can adjust and monitor the temperatures anytime and anywhere. It has lots of extra features. It can be set the threshold for temperatures and also can control the room temperature if I am out. It controls the temperature by heating or cooling. Of course you will need to have the cooling and heating devices plugged in. I don’t have the heating device hooked up, which is fine for the summer. I set the desired temp to 65F so the a.c. will kick in when the temperature is higher than 65F.

I use this together with a chest freezer for home brewing purposes, both lager fermentation (48°F - 53°F) and lagering (32°F - 35°F) The controller works well in this scenario and the fact that Im able to connect it to my WiFi network and both monitor and control it from anywhere in the world is a real bonus.

I haven’t yet used it but it came fast and is really good quality

It works pretty easy setup was easy no need for instructions, connection to the app easy. I dont have any lab grade gear to attest to the accuracy so they get a pass on that. I take down 1 star for Temp control and ease of use because of the fact it beeps at you non stop until you press a button any time you remove power. For my personal use case this is fairly often and so thats annoying. Also I bought this one because it works with the smartlife app which works with Alexa, however be aware you cant set or retrieve temp via Alexa. I use this as a secondary temp controller to act like a watch dog for my primary temp controller. I use it to control a heater inside a 3d printer enclosure, I had my primary controller freeze in the on state which had my every metal surface in my enclosure around 90 Celsius; so I now run two so the power gets cut in an over temp situation.
