Like many here I also want to have the Balanced mode back. I have been playing with the new utility pricing and have been able to nearly replicate the Balanced mode through "human learning".
I am on the PG&E + CCA E-TOU-C plan which just has Peak and Off-Peak periods and I am also a net generator. I want my system to do the following.
- Maximize exports during Peak by discharging Powerwalls with all solar going to the grid
- Do not discharge Powerwalls during Off-Peak
- Minimize imports while charging Powerwalls from solar by prioritizing house first than Powerwall
- Powerwalls are at 100% before Peak
I have set my Utility Pricing to the following and it getting me what I want.
- Off-Peak
- Buy Price = $0.07 / kWh
- Sell Price = $0.06 / kWh
- Peak
- Buy Price = $0.10 / kWh
- Sell Price = $0.09 / kWh
As you can see, as the sun comes up it starts going to the house first, then the Powerwall, and then to the grid when the Powerwall is fully to goes to the grid. Once Peak starts at 4:00pm the Powerwall discharges until the end of Peak at 9:00pm and then it goes to standby.

So, why these values? Both Buy and Sell Off-Peak prices are below the Peak Sell price, so the "machine learning" won't think that it makes sense to discharge the Powerwall during Off-Peak. The difference between the Buy and Sell prices is more than 10% so that the "machine learning" to won't take into consideration the 90% round trip efficiency.
For the Tesla developers that occasionally read these forums, please just give us explicit control functionality by period to prioritize Powerwall charge and discharge behavior so we don't have to reverse engineer around what your "machine learning" algorithms are doing as they simply do not have the information necessary to know if they are doing a good job or not.
