@jasonacox - I think I've run into a wrinkle with this - at least assuming this is used for system vitals. I've only just upgraded to 4.4.6 (been busy) and while I can see the system vitals, the voltages being reported for solar, home and grid are around the 415V level, while the powerwall reports around 235V. I'm guessing the 415V is being calculated assuming 120V/phase? I'd expect all of the voltages to be around 230-240V locally.

I did look around both here and in Powerwall-Dashboard, but didn't see any issues addressing this. If there is a live discussion, could you point me at it. If not, would you prefer an issue raised here or under Powerwall-Dashboard?

Yes, let's open an issue. Where do you see the bad voltages? When you get a chance, send me the raw data you see for /api/meters/aggregates (e.g. http://localhost:8675/api/meters/aggregates)
