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?

I find three charging rates (in AU): raising backup reserve above state of charge 1.7 kW per battery switching to Backup mode, via OwnerAPI 3.3 kW per battery switching to TBC mode, whilst on OffPeak I see 5 kW per battery Discharging I can only seem to manage full 5 kW per battery using the...

Looks like ChargeHQ is already using the energy component of the FleetAPI. I would certainly like better manual controls for charging and discharging my Powerwall. The OwnerAPI is reasonable for charging on command, but you need to use the TBC workaround for discharging which isn't reliable...

This graphic was from Home Assistant, which lets me show which mode and zoomed in power flows. Here is the same day in the Tesla app, see the deferred charging from 6am - 8am.

I replied to your post in Energy: https://teslamotorsclub.com/tmc/posts/7911992/ See image on delayed charging until 8:10am.

Aussie powerwall user here. I achieve morning exports and delayed charging using TBC and defining a morning and evening peak. The battery will export during the morning peak, or if you switch Exports Solar Only then it will export solar that isn't consumed by your household load. You can see...

I logged a service request for my 2020 model 3 and got it installed today by Tesla for $263.
