I was able to access my MMPT SmartSolar 100/50 Charge Controller via the Victron app for the first few months after it was installed - however it no longer will show up in the Victron app. I have the Victron battery monitor which continues to show up in the app with no issue. This is all being done on the same Iphone that I have had since the beginning. I have reset all bluetooth on my phone, reinstalled the app, tried other phones - but the charge controller does not show up on bluetooth. The charge controller appears to be working fine, I just can no longer access the data via the app. The controller hasn't been moved or tampered with in anyway. Trying to figure out if there is something else I can try...
