This low energy RAPT enabled Bluetooth Thermometer is compatible with the Gen 4 BrewZillas and RAPT Temperature Controllers and RAPT Fermentation Chambers. It will not work without one or more of these devices.

By receiving multiple BLE thermometer sensors the BrewZilla can make smarter and more automated decisions on how to control the brewing or distillilation process.  For example a BLE thermometer can be placed into your coolant water so you get an alarm if the temperature is too high, a BLE thermometer can be put into the middle of the malt pipe so you can more accurately control elements switching on/off to achieve a core malt pipe temperature etc.
