I had successfully added a smart solar not to and easy solar 2. System via direct connect ports and it has been working very success fully over the last 4 days but this morning it’s disappeared from the system and UX display. I have tried connecting via usb and direct but nothing I have set mppt back to factory defaults but still not showing. I believe the two systems are linked via Bluetooth. I did add a display to the mppt last night. So I am at a loss. See pictures
