It looks to me like some kind of CT issue. Note also that your home load seems to increase in the morning commensurate to the solar production. It's like one of the solar CT's is being added to the home load some of the time. I think your installers need to take another look at the CT's. The TEG...

Actually, those with battery storage do also qualify for EV2-A on a pilot basis. I haven't heard that they've exhausted the 30,000 battery-only slots, so I suspect you could change to that if you wanted to. See https://www.pge.com/tariffs/assets/pdf/tariffbook/ELEC_SCHEDS_EV2%20(Sch).pdf I...

My understanding is that what will no longer work is refreshing the access token when it expires. This is separate from the new firmware that requires authenticating to get to the aggregate and soe numbers locally.

Any reason they wouldn't be able to use this in the web UI to the gateway to replace the current animation? I'd assume that they're going to upgrade both the local web UI and the mobile app at the same time. The SVG power flow animation in the local web UI currently is pretty similar to the...

E-TOU-C has 4-9 pm peak and a baseline allowance that is 7 cents cheaper. E-TOU-D has 5-8pm peak and no baseline allowance. Both plans have minimal price differences between peak and off-peak during the winter months, so it's really only during the four summer months (June-September) that the...

It seems to me that given that the default configuration for a Powerwall not on a VPP is 0 export, it's already configured the way they want.

One note - if you are a net producer, it may be worth considering E-TOU-C instead of EV2-A for the lower differential between peak and off-peak. On E-TOU-C, your solar production will be credited at a higher rate so it would be unlikely that your peak usage would outstrip the credits you built...

Yes - just add "insecure_skip_verify = true" to the configuration to get around it. This is my configuration: [[outputs.influxdb]] urls = ["http://localhost:8086"] database = "powerwall" skip_database_creation = false retention_policy = "raw" [[inputs.http]]...

One helpful analogy is to just think of the electrical wires as water pipes. The solar inverter is pumping water into the pipes. If it pumps fast enough that it is generating more water than is being used by all the devices in the house, the excess will flow out to the grid. If you think about...

I'm using the same technique with the PurpleAir sensor as I am with the Powerwall - logging the data directly from the sensor to influxdb using telegraf. For the PurpleAir sensor, the url is simply http://<ip>/json?live=true. Note that the PurpleAir Wifi radio gets warm, so I had to subtract 7...

I'm in backup-only mode right now. The green line dipping represents the Powerwalls charging in order to replace the "vampire drain" for the previous day or two. I prefer this direction because it is easier to compare the Powerwalls' discharge to the load when they are supplying power.

That's actually coming from a PurpleAir monitor on the back of my house - it's ambient temperature. I'm also logging the data from the nearest Weather Underground personal weather station for cross-referencing.

One other easily overlooked aspect of E-TOU-C is that the baseline credit essentially turns it into a tiered plan. During the winter, the tiers make much more of a difference than the TOU.

For data collection, you don't need to log in. The main reason to log in used to be for automation, and it appears in the newest software version they don't allow changes to the settings (other than netwrok) without first physically toggling the switch on one of the Powerwalls (to avoid remote...

The password the installer wrote down might be for the installer login, not the customer login. There isn't really a lot you can do with a customer login, apart from reconfiguring the network. Is there something specific you're looking for in the web UI? For me, the most useful part is what you...
