Review on 🌡️ TESSAN WiFi Smart Temperature Controller: Plug-in Digital Thermostat for Heating and Cooling, Compatible with Alexa and Google Home, App Monitoring, Recording, Alarm for Homebrew, Seed Germination, Reptile Keeping, Greenhouse, and Aquarium by Laura Wright

I have a heat gun and water heater for my reptile, but the only thing that is giving me inaccurate readings is this thing. ALWAYS. Its heating and cooling functions and application are useless as the setting is geared more towards running the heating and air conditioning for a person who doesn't need specific heat. So if you need an inaccurate supplemental thermostat, look for it. If not, AVOID IT as it says its smart app feature works but I can't figure out how to use it properly based on what I've described. It works like a remote switch if you're trying to use it with an Amazon home, but for this price you should buy something more specific and probably interact better with your system. My views please, I'm trying to warn you.
