I run an open source energy management package called EMHASS which uses a mathematic linear programming model to create an optional schedule for battery operations based on forecasts for future solar production, household loads as well as buy and sell prices...

Thanks for your assistance. The TEG wifi and TeslaOne also weren't working very well, so I have reset gateway and things are working 'normally' now.

I do hit the gateway pretty hard with the FleetAPI, but have very much wound that back. I do have Home Assistant hitting the gatewayAPI every 30 seconds for status updates. The gateway seems to go into a non-responsive state (FleetAPI is still updating), I can ping the local gateway, port 80 is...

I'm registered for FleetAPI through netzero, do you make ongoing API calls on my system when I'm not using netzero either mobile or web app? Not sure what update_unknown means: https://github.com/vloschiavo/powerwall2?tab=readme-ov-file#get-apisystemupdatestatus ```json { "state"...

Any speculation that the updated M3P will support Powershare?

I suspect my Powerwall Gateway is rebooting, perhaps high CPU from API calls, but very difficult to debug, especially as the LAN interface goes off line regularly. NetZero gives me some great diagnostics, including uptime which looks suspect. Now that the vitals endpoint has gone, how is...

Tesla Charge on Solar does this natively. It will prioritise charging EVs and will hold the Powerwall battery at the current State of Charge, until EVs pass the Charge of Solar threshold. I also do the same thing with Home Assistant, so you have lots of options.

We have a couple of sources of tariff. The Amber API does require a key, which I can generate for you. ChargeHQ integrates Amber pricing this way There are alternatives which publish the spot price are publicly available with OpenNEM and AEMO.

I have half hourly pricing with Amber Electric in Australia, who have a really well supported API to retrieve pricing. They have their own optimized scheduling, but I have rolled my own using Home Assistant. I have played around with dynamically setting the tariffs in the Powerwall based on the...

Does anyone know the structure to call the CHARGE_ON_SOLAR API endpoint? https://github.com/timdorr/tesla-api/blob/670596c7348617f9e3b3a97ee335e84227a9b49a/ownerapi_endpoints.json#L242

You need to use the Time Based Control hack to get Powerwall to export to the grid. Setup a utility plan in the Tesla app with a high sell price, wait about 15 minutes for the settings to be accepted and then when you switch to Time Based Control it should start exporting in about 3-5 minutes...

Thanks for the update. Interesting my nameplate_power has gone up from 15 kW (3x 5kW) to 16500! Looks like my curl isn't modern enough ;-( The legacy method works:

The Home Assistant integration was breaking all over the place, and many users thought it was the end with FleetAPI, but no, it was a simple X-Tesla-User-Agent string that needed to be updated and we are back online with the OwnerAPI, but it will be good to switch to the supported FleetAPI as...

Nice, I have managed to download the API_TOKEN_FILE from your developer link and access my energy end points using your script and the FleetAPI. I had to modify your script as my vehicles also came out of your scope and productlist, so my powerwall gateway was item [2].

@offandonagain Looks like the OwnerAPI has stopped control of energy products as of today ;-( Any opportunity for Netzero to allow control?
