Wondering if it is possible to add a feature to change the SPAN to off grid via HA Trigger

[blair0011]

I have a PowerWall (PW) 2 which predated the SPAN install so my installer decided that the PW should define grid outages because it already had the monitoring clamps installed. Well now that you have to use the tesla fleet api to do this my older SPAN Panel 32 circuit can't talk to the PW. So I have everything setup in HA but I can't find a way to tell the SPAN to go into off grid mode. Is it possible to do this? Right now I have HA send a notification to my phone so I can do it manually but I would rather HA did the change and notify me so I can verify. Thanks

Every API we have access to is exposed in the integration which is indeed limited. The phone app talks to the cloud in the walled garden.

I was afraid that was the case, but couldn't find a API mapping anywhere to say yes or no. Do you know if anyone has documented the SPAN API? I have the time and inclination to poke around and see what is going on. Thanks.

The only API I'm aware of is either the rest or the OpenAPI -
curl http://[your-ip]/api/v1/openapi.json

I wasn't aware that the app let you put the panel into off-grid; I assumed off-grid was a function of whether the SPAN panel sensed power on the mains, no?

I assume the PW is wired into some lugs on the SPAN panel, not the mains? The way you describe it makes it sound as if the PW is feeding the mains on the SPAN Panel.

Is the state your trying to achieve reducing the load by managing circuits to only the necessary circuits, which of course you can do by altering switch states in the existing integration?

The app does let you go off grid. The option is at the bottom of the Tesla PowerWall pane or found under Testing Features at the bottom of the Settings page. I had to use it once after a delivery truck took out the local electrical junction box. The grid was down for 9 hours then, and I found out about the local tesla password issue then.
