Review on 🐠 Inkbird C929A: Smart Digital WiFi Temperature Controller for Aquarium Fish Tank- Enhance Aquatic Life with Wireless Thermostat for Reptiles & Terrarium by Vanessa Carstens

I bought this to control a reef tank heater as an added safety measure - nobody wants to cook their pets. - Easy network connection. The app works fine. I adjusted the accuracy of the temperature readings using the app and a traceable digital thermometer. Dislikes - temperature fluctuations of several degrees occur randomly; the heating only starts when the minimum setting is clearly undershot. Inkbird is not stable and causes large temperature swings in my aquarium - worse than using a thermostat only in my heater. I'll take it off and wait to get a proper aquarium controller.
