I will just have to wait until some charger manufacturer deems it profitable to make something, that is working out of the box, and i only need to feed it my one surplus solar sensor, and it will do the rest.

You can build your own smart charger with SmartEVSE. SmartEVSE has a build in Solar mode. With this Solar mode your charger will only charge your car when solar is otherwise send back to the grid. It’s also a load balancer. It charge your car only with the current that is not needed for your house.

No programming needed. You need only a few hardware components (a contactor, a charge cable or socket and a metering device).

See Smart EVSE v3 controller for the SmartEVSE hardware.
And for the open source code GitHub - SmartEVSE/SmartEVSE-3: Smart Electric Vehicle Charging Station (EVSE)

Got Tesla Powerwall battery and solar at home. Recently switch to Amber Electic (Australia) for wholesale price. I can see during summer and Ausgrid Solar Fit in price is negative specially between 10-3pm. Try to get lowest possible export power during that time. Although Amber app does a bit. But it seem not good enough. My home Powerwall get fully charged within about 3 to 3.5 hours. I want set Tesla to export all excuss solar power to grid before 10am or even 10:30am except rain days. Installed Tesla powerwall and Tesla custom integration and config properly. I can see switch mode of Tesla Powerwall power export mode. But it only gives . While Tesla invertor should have default (1, exccess power charge battery first, 2, Solar send to Grid, and 3, Solar & battery send to grid). How to match them against power export mode (Solar or Everything two selection) in Tesla custom inegration?

Here is the script I did. But how to resume Tesla control back to charge Battery after 10am? Or even the script doesn’t do what I want to.
