The PowerWalls were installed 11 days ago but are not yet operational due to a fault. It’s been very difficult to get Tesla service but an engineer is due on site tomorrow.
Once up and running, I’m happy to be a ‘test bed’ on this.
My first intention is to try to modify the PowerWallInterfacer.
I’ve previously seen the link you’ve provided but frankly find it difficult to understand. This link might also be helpful …
In anticipation I already have a dedicated RPi on site running emoncms. Of course I don’t yet have a URL for PowerWall to put into the PowerWallInterfacer which explains why I’m getting the following output when I restart emonhub. As an aside - watchman is another RPi on site which collects data from 4 x EmonTx/RPi’s - inverter generation meter, grid meter, pool and EV charger.

I’ll keep you posted and will be asking for help without a doubt.
