Upgrade your Conical Fermenter controller and get built-in wireless control!

Already using the Grainfather Conical Fermenter? Get the new Grainfather Conical Fermenter Pro Controller, install it on your current unit and benefit from wireless control.

Connect the Conical Fermenter Pro Controller to the internet and the Grainfather App, add fermentation tracking devices, and control/monitor fermentation from anywhere! Plus, it’s even got an improved digital display and water resistance.

It also upgrades the way the controller attaches to the fermenter by making the attachment semi-permanent. Rather than clipping on and being held in place by magnets and connecting via pogo pins, the new controller is a wire harness and screw-mounted directly to the body of the conical fermenter. Installation instructions provided.


  • Control your Grainfather Conical Fermenter Wirelessly.
  • Monitor and adjust your fermenters from anywhere in the world!
  • View temperature data via the Grainfather Connect App.
  • Ability to set fermentation schedules.


  • Wireless Controller
  • 4 x screw hole plugs
  • Self-fusing tape
  • Fermenter socket cap
  • Instructions on how to install the new controller to your current fermenter

Note: This does not include the Grainfather Conical Pro Fermenter.
