This update to the control box will completely transform brewing on the GRAINFATHER making it completely controllable via Bluetooth from any device or directly on the box.
Complete control over the heater power using a modified PID algorithm, gives more accurate temperature control and removes the need for the Element Variation Switch. No longer is the element simply on or off.
A Bluetooth connection between your device and the new control box allows the unit to be controlled from your device, and give you updates to your device while still allowing complete manual control on the system itself. Our new auto mode uses this Bluetooth connection to automate the control of the Grainfather, making brewing a breeze.
New simple user friendly design – screen/buttons.
Water resistant face (no cover any more).
Fits all Grainfathers currently on the market (attachment lugs can be moved to suit), and you can swap between Celsius & Fahrenheit as desired.
