Work on additional charging profiles

[shreddedbacon]

Temporary override

Setting the powerwall to 100% backup instead of self powered mode
Adjusting the charge current to maximum

Time based temporary override

In addition to the above, having the ability to stop it between certain times.

My utility provider has a peak rate from 4-8PM where if I consume high kWh, then I get charged additional. If I have the car charging on a temporary override, I need to make sure that I stop it from charging at the maximum at 4PM to prevent consuming from the grid and getting an excessive usage bill.

Initially I wanted to avoid having time profiles in the controller, but purely charging off solar is not viable 100% of the time (overcast or dark/wet days), and I have found myself having to dip into this situation on occasion.

I'm interested in news, helping out with writing, testing, etc.
I have two M3's, one Gen2 station. I am considering solar-mostly charging. Power in my area is 11 cents, so adding external batteries and other hardware is difficult to justify, although not impossible. Weather also isn't great, so a charge-anyways option would be sweet. A contactor or two would work, but I would rather a smart solution that knows how much solar is happening. Thx

Hey thanks for commenting.

I've basically abandoned this version of the controller since Tesla introduced the charging rate API directly in the cars a year or so ago. I've been slowly working on changing this controller to use the API instead of talking directly to the wall connectors, but I haven't factored in charging profiles at all yet, but I'll see what I can do, no promises as this is just a side project

I am super-simplifying my setup. What would I need to just tell my TWC to set a current, coming from another measurement device? Could IFTTT do this? Or a Wifi Arduino/Pi? I just found out that Emporia uses an ESP32 controller, and that it can do some MQTT things which would be useful for throttling power consumption. https://community.emporiaenergy.com/topic/api-to-pull-data/ Maybe ..... *From:* Ben Jackson ***@***.***> *Sent:* Tuesday, September 5, 2023 3:13 PM *To:* shreddedbacon/twc-controller ***@***.***> *Cc:* Hans Schulze ***@***.***>; Comment < ***@***.***> *Subject:* Re: [shreddedbacon/twc-controller] Work on additional charging profiles (#4) Hey thanks for commenting.
