Installed and tested with nothing connected. All good. Connected to Bluetooth in the app.
Plugged in SmartShunt and inverter. Now can not connect to Bluetooth. I have rebooted phone, unpaired Cerbo and rebooted Cerbo via GX50. I suppose the next step is a factory reset. What the heck?
I could only ever get a good connection by using the WIFI connection. Set your phone or computer to the wifi on the cerbo box. Then open Victron connect. Even though Victron put a blue light on the cerbo box the bluetooth seems to be elusive.
