I finally was able to get monitoring to show up in the app two weeks after PTO and calling every day, having reps tell me they needed to manually register the inverter and to wait 24hrs only to not have it report, to having reps tell me the inverter wasn't connected and communicating even though other reps said it was fine and I could see the inverter making requests to Tesla servers from my router logs, to having reps elevate to tier 2 support saying the registration somehow wasn't "sticking" and that they would follow up in a couple of days and never did.
Eventually, I got a rep that actually took the time to read something and got the app to report right over the phone, no need to wait 24hrs or restart the inverter. It even had all my old data going back two weeks. Nice. However, I noticed that it seemed like the app was reporting data exported to the grid as being consumed by my house, making my house consumption look like solar production + grid export, a huge amount. I mentioned how it seemed like the data would be correct if the consumption from the grid was just inverted and the rep seemed to understand and agree and submitted a tier 2 ticket to hopefully insert that "negative" sign somehow, and I should hear back from them in 24-48hrs. Approaching 48hrs and still waiting to hear back though...
I've read elsewhere of someone else having a similar issue and Tesla being able to resolve it on the back end. I supposed I could go muck around with the CTs and flip one so the sign changes, but then all my old data would still be wrong, so I'm hoping Tesla can fix it on their end, and I'm not to comfortable messing around since I have solid exposed bars coming in (not insulated wires) and there's a plastic shield around them where the CTs are now buried inside. The Neurio has CT 1 and 2 connected. Not sure if I would have to change to 1 and 4 like you guys are doing.
Another thing that was interesting is that at night when solar production is zero, because now grid consumption is looking like export due to the inversion, in order for the app to "balance" things, it seems like it assumes it all comes from solar, and my home consumption is zero, so I'm magically producing 5kW of solar in the middle of the night when I'm running my dryer. It seems like there's some extra logic baked into the logging to make sure things "balance" even though they can directly measure the solar production. Their calculation must look something like home consumption = solar production + net grid consumption (negative if exporting), but if this equation becomes negative, and solar production is 0, then make solar production the negative of net grid consumption. Boggles the mind why they would do this since the solar production number is a golden known number and presumably can't be wrong.
Despite that, I also noticed my data doesn't seem to be "real-time" but delayed by about 30min. Does anyone else have the same issue? I have a Tesla inverter with Neurio. When I log into the Tesla inverter and look at the site meter values there, they match what I see on my smart meter in near real-time. In the app though, I can turn on my dryer, but the power flow won't show the 5kW until about ~30min later, and the graph history matches and shows that ~30min delay. I can pull to refresh the graph and it will show the last recorded data point within the last 5min (so if it's say 1:32pm right now, the graph updates and shows the last datapoint at 1:30pm), but it matches the power flow screen, and everything has that ~30min delay. If I turned on my dryer at 1:25pm, I won't see it reflected in the app until about 1:55pm.
