I have a BMV712 Smart that occasionally will fail to sync with the VictronConnect app.
When I open the app - instead of my custom name - it will show the generic name, and when I click on it, it does the
‘connecting 20..40..80..’ then the ‘Fetching Data’ comes up - and instead of that finishing in a second or 2 - it spins forever.
In that mode I can click on the ‘I’ button and it will show the unit info. I can walk over to the unit itself and read anything I need to.
This will continue for maybe hours - then the next morning or so - I bring up the list of devices and there is it - custom name - and immediately connects and fetches data. Very odd.
I actually have 2 independent house banks - so have 2 BMV712 monitors - and this only happens on one of them.
