I have 3 Smart Solar Chargers MPPT 100/30. I can connect to 2 of them but unable to see the third. Otherwise all 3 appear to be functioning correctly. Have tried disconnecting third charger and deleting and reinstalling app, but no change. Any suggestions?
Check if it is visible through the phones BT settings (but don't pair) sometimes you have to forget it there first if pairing was done that way first.
Otherwise if they are all smart, the fact that you can see two of the three means one has a problem.
Either the internal BT has been switched off in settings, or it is faulty.
One way to check is with a ve to usb dongle, or a ve direct to BT dongle, if you want to buy any of those or the other is to return it for an RMA.
There are some other tips in the troubleshooting section. But most don't apply to you situation.
