The newly installed EV Charging Station had 1.23 installed, so I tried to update it via the VRM. This failed. So I downloaded the firmware and installed it directly via the web interface. Ran up to 100% and reported success. However, at the station itself the screen is black and it says "system data error". However, I can address and operate the station via the web interface, but the display doesn't work. The web interface says v1.27. Does anyone have an idea?
