VRM dashboard - grid tile reporting wrong current

The calculation for amps on the grid tile on the dashboard seems to be using the wrong maths to determine current. See attached. Looks like 10V/W instead of W/V.

have you got ess turned on and has the correct meter type been selected. ie the inverter/charger and not external meter, it setting defaults to external meter from memory

Nope. Problem still there across all the sites, it appeared quite recently. @Guy Stewart (Victron Community Manager)

I've also noticed the same issue, my Quattro is the grid meter, everything else is on AC out 1.

I have ESS turned on, looking in the ESS assistant I can't see any setting for a meter. I do have a E112 meter in the system, but that is measuring the energy from a seperate PV system on AC out 1, and is working as expected. Everything looks correct apart from the amps reading shown above.

Maybe it's a problem with the Venus OS version. I'm still on version 2.82 and the numbers in VRM are correct. I'm using an external meter for the ESS, a Shelly 3EM.

I don't think so, mine is up to date at 2.93 - no updates available.

Did you have the problem before you updated to 2.93?

I've no idea, I updated the Cerbo a few weeks ago, the AC was only done this week, so its my first few days of full operation.
