Had same false triggers for Vehicle Charging. Those at 3:01 and 3:02 were phantom charging triggers.

I have both a Tesla AND Enphase PV systems at my home. Is it possible to sign in to both?
Just discovered this app and can't wait to try it out. I skimmed through the 7 pages of posts, so sorry if this was asked & answered earlier. Is there any integration or ability to upload "Green Button" data of my smart meter usage from my utility?

Unfortunately, due to ridiculous utility regulations in my location, I have two separate systems. The tesla gateway cannot and does not measure production and data from my enphase PV system, only the PW and separate array of panels that are dedicated to it. Hence the request to use my utility green button data which is the net total of both systems.Which data are you hoping to get from Green Button downloads? From my experience (PG&E), the only data available is 15-min resolution historical grid import/export, with a day delay. Tesla already has both live data and 5-min resolution historical data for grid import/export.
A related feature is coming in the next app version: aligning monthly data to a configured day of month, so you can track your utility billing cycle.
Enphase login is meant for standalone Enphase systems. If you have your Tesla system tracking Enphase PV production, you'll get better data from Tesla. If you do have two independent systems then like @skepticcyclist said: you can't login with both. However the Netzero web app makes it easy to have another login (or even multiple logins with browser profiles).

NetZero looks great, but unfortunately, not for me due to the limitations that are admittedly specific to my situation.
TL; DR: It was that way originally, but the technician came back out after a month and changed it because of the utility's tariff code.That may very well be the case, but I always try to learn about such requirements because it allows me to improve the app in the future (and multiple systems is not an uncommon scenario).
You mentioned the Tesla gateway cannot measure your Enphase production, I'm curious why. With multiple systems you can install a separate solar CT (meter), which allows Tesla to add up all solar production. This is not just an accounting issue, but also allows the Powerwall to make better decisions on when to charge and discharge.
And while the utility data will give you accurate grid import/export data, it doesn't have visibility into solar production (or anything else behind the meter).

2. I'm aware of missing vehicle information for some users. I'm still investigating this, but it might be that Tesla doesn't include that information in the new Fleet API.
May I know if there's a chance to the algorithm used by Tesla to calculate the PW degradation? If I remember correctly, it showed 1 % earlier in the year, now it's showing only 0.2%, magically it's been improved.
Thank you for your detailed explanations.It's common that there will be some fluctuation in the measured capacity. Powerwalls constantly estimate their "full pack energy", but that's not a precise measurement -- it relies on measuring voltage/current and is sensitive to temperature, charge/discharge rates, etc. I won't pretend to know how Tesla does it, but if you want to learn more about this problem, the search keywords are "estimating state of energy in lithium-ion batteries".
To track degradation over time, you'll have to ignore short-term variation and look at a longer time horizon, probably years. Tesla warrants 30% degradation over 10 years, which means they expect the degradation to be substantially lower than that. I'll add historical capacity values to Netzero at some point, but it hasn't been a priority because of this same reason -- a lot more historical capacity data is needed before it becomes useful to observe trends.

This is a really cool feature. I compared my usage for last month since my billing period just ended, but the Grid net consumption numbers were off by about 10%. I then double checked and my billing period ran 3/14 to 4/14 (32 days). Can you add an option to either have number of days in billing cycle, or maybe a +/- xx days to help compensate. I’m not sure of the best way to deal with that.
Thinking through this, an easy way to change the "Start Date" without having to go to settings, and then a + / - to adjust the end day for the Billing Month view. Aesthetically where to put this on the app, I'm not sure. Or worst case put the +/- in the setting page.I'll think about that. The billing cycles for my utility (PG&E) range anywhere from 28 days to 33 days, without any clear pattern.
Yes, this is what I came here to find out. This would be great in the incentive program that I am in with the local utilities. They will only credit me for X amount.the automation updates are great!
Is there a possibility of future ‘export XX kWh’ from powerwall /then/ turn off export?
