Yes, you can upgrade your old manual G30 controller to the Connect Bluetooth controller.
The old manual G30 includes the T500 version, so both can be upgraded to the Bluetooth one. Once it’s fitted, you can control and monitor your brew from the Grainfather app.
A few things to know:
- Voltage must match. The controller has to be the same voltage as your boiler (110V or 220V). They’re sold as matched pairs and can’t be mixed. Please confirm which voltage your G30 is before ordering.
- Fit. You may need to adjust the lugs on the back of the controller so it sits properly in the bracket. Here’s how: Why doesn’t my G30 Controller fit in the bracket?
- Element Variation Switch. If your boiler has one, leave it on “Normal” from now on. The Bluetooth controller switches between elements automatically. More here: I have upgraded to the G30 Bluetooth Controller, what do I do with my Element Variation Switch now?

No internet needed. The controller connects over Bluetooth, not WiFi: Do you need internet when brewing with the G30 / G30³ Bluetooth controller?
