Software v21.31.0
- Thread starter m3-pw2
- Start date
I just got that as well - I assume it was a rollout planned before this. I am noticing a different behavior today with my PWs, which are in backup-only mode. Previously, it would do a larger draw from solar every day or two to charge them back to around 98%. However, as of today they are charged to 100% (no storm watch here) and it is frequently (looks like 6 times in 4 hours) showing small pulls as if it is attempting to maintain 100%. Not sure why the change, and I guess I will see if that behavior persists.

I am still in Storm Watch, but it also seems to have changed behavior and now trickle charging to keep it at 100%. Not sure if this is temporary after software upgrade while battery re-calibrates or it will be a permanent change.
I've been on 21.24.2 for a couple of weeks now.. not sure what the changelog is, but, yes, my web GUI has the same shrunken powerwall display:

Here is teslas information on how to access your powerwall gateway locally:
Connecting to Tesla Gateway and Powerwall+ | Tesla Support
If you lose internet or cellular connection, view instructions on how you can monitor your system’s power flow and charge level via web browser by connecting to your Gateway or Powerwall+.
Not sure how this might or might not be impacted by powerwall+ though, as its the tesla gateway you access, not the powerwalls directly.

Thanks for the link to the article. I was able to connect, but apparently I have to connect to the Gateway’s WiFi whenever I want to monitor, is that right? As long as the Tesla app is working, not sure when I would do that.
The reason that is there (for the most part) is so that you dont have to have internet to monitor. If (for example) you were in an outage situation and did not have internet, if you dont have cellular active on your gateway or are out of range etc etc, you can still log on and monitor your own equipment locally.
There isnt a lot you can do there other than look, but it gives you a way to look without the tesla app.
While there isn’t much to look at in that interface there is a lot of API data available, so I use the API data for better graphs/reporting, you can also see in the battery graph by the vertical dotted red and green lines when it stopped received data during the upgrade to 21.31.0, in the graphs on the right side the top one also shows the solar altitude in percent and how it corrolates to my solar production and the grey in the battery chart is the cloud cover in %.

There are a couple pre-built solutions out there like GitHub - liveaverage/docker-powerwall-dashboard: Grafana dashboard showing trend & historical data polled from Tesla Powerwall 2 API served up in an easy to use docker image
However I went a little more manually and used the python module from here GitHub - jrester/tesla_powerwall: Python API for Tesla Powerwall and have some scripts to handle sending the data to influxdb

Also bumped to 21.31.0. Other than the partial battery graphic, the way power moves around seems different. Previously, if the battery was at 100%, solar generation would show going to house and grid. Now, it seems even at 100%, power flows solar to house, grid, AND battery, with occasionally from battery flowing to house as well. This occurs when more solar is being constantly generated than house can use. It's almost the same thing that has always happened where, with plenty of solar being produced, the grid briefly flows in for the gateway to check that it's still live.
Seeing similar differences in battery power flow, in the attached graph you can see that I hit 100% battery at 11:58, and then it continued sending about 100W of power to the battery for a little while then started bouncing between sending and receiving power from the battery. Prior to 21.31.0 it would drop to 0W or maybe at most 20W trickle to the battery.

Yes, this is what I am seeing along with the behavior I described in my earlier post. As an example, yesterday I showed a flow of 0.9 kWh from PW and 1.9 kWh to PW. For the entire month of May (where I had only a very brief outage) I show 0.2 kWh from PW. So in one day, my PWs apparently exported more energy (with no outages) than in an entire month.
I don't know if there is some sort of battery management or other purpose behind the change, but this is a case where prompt, complete release notes would be helpful to understand the change in behavior.
OMG lmao.... im wiping coffee off my monitor from actually laughing out loud right now.....

Sorry, couldn't resist. Send me the bill for the monitor and I'll submit it to Tesla for payment.
