Hello

The EM24 (latest firmware) somehow glitched, and the ESS switched to bypass. This is the first time it’s happened in four years.

The strange thing was that the hoped-for reset by disconnecting the N (350 mA fuse) at the device just left the meter running. So I had to switch off the three phase conductors, then use a torch to re-enable the meter for Tibber :upside_down_face: Apparently the GarloGavazzi also gets its supply voltage from 400 V across two Ls?!

The depths of the menu on the smart meter are unfathomable; there’s probably a soft reset in the control panel too?

The EM24 gets its supply voltage from L2 and N, or from L1 and L2, so disconnecting N won’t achieve anything.

I think there’s also an option in the menu to reset the settings, but I don’t know whether that would have helped in this situation.
