Hello,

just reporting a weird issue. VRM portal is unable to update EV Charger with display.

It throws a weird error.

The problem is, that VRM portal recognizes C025 firmware version as C026. When firmware is uploaded manually, it works. It is a very confusing error and took me a while to figure this one out.

Please see other screenshots. I had the same issue on 2 sites. These chargers were from 2022, some of first pieces delivered actually.

I think it is worth checking it out. @Lpopescu @mpvader

Victron Expert T-shirt appreciated :slight_smile:

Also, just to add to this. To version 1.22 it was updated via VRM I think. Locallt, the display was not functional with 1.22 version until upgrade to 1.30 (C025) - so I think there was some issue in regards to fw version / target hw check and hardware was actually running C026 firmware version.

I think the wrong 1.22 firmware was manually uploaded. Initially, it was possible to do that, verifying the hardware version was added later.
