mppt connect gone / no entities

[gkathan]

hi,
I had my mppt 75/15 integrated successfully and saw values coming from the entity ... but yesterday suddenly the connect was gone / lost ... tried to remove the integration and re-add it with no success ... quite puzzling as it still works fine when I directly connect via victron-connect app
any hints?

...having fiddled around now to understand my issue better - the current state looks like:

• have completely deleted all victron devices and victron integration
• freshly added the victron integration via HACS link
• it detects my victron mppt 75/15 charger device
• gave it the correct advertisment key
• !! it does NOT list eny entities in the overview !!
• in the debug log it shows (blue lines) that it successfully sends advertisment key and gets in second blue line the correct paylod data from victron device

I also have the MPPT 75/15 - what did you put for the address field and where did you find the "Advertisement Key"?

I thought this connected over bluetooth so where would it have an IP address?

You have to connect it with the Cellphone APP first, then click the Gear Wheel, Top next to the Device Name,
in Settings Window click the 3 Dots -> Product info, scroll down to Instant readout details, Encryption Data > Show
MAC Adress is the Address you need, Encryption Key is the Key.

But sadly its not will Crash then if the Load Current is not 0.

I tried it to fix by myself, but my python skills aren't that good.
It would have been working in earlier versions, but the the last changes may broke it.

@herrfeuer's change #101 works for me.
