Change Priority

[trinitron79]

It seems to me that "Priority" isn't something that shown, not seeing it on Loadpoints or cars.

Would love if this could be gathered so I could create automation that changes the priority depending on SOC of car.

I have 2 EVSEs and 2 EVs, It's be nice to have some kind of automation that checks the two cars at 9am and just sets the priority to the car with the lower amount.

Where you can adjust the priority in the evcc UI? Right now I am only aware that the priority is a configuration setting if a loadppoint.

never mind - found it - /loadpoints/{id}/priority/{priority}

Awesome thank you!!! Was able to kick out some automation already and check that it works as hoped!

Added a delay changes as it was getting out of sync. Wanted to 5mins to make sure we had extra power, then added a higher wait time of 10mins (testing, will lower it to around 6 or 7) for the priority 1 device.

I also had to ensure both vehicles had a charge Priority of 0 (Default). In the UI this is under Advance Settings of the vehicle. If you have this set it seems to overwrite the Loadpoint Priority. I didn't see a way to set vehicle priority in the docs or api so do not believe it's currently exposed. Setting them both to default 0 seems to cancel them out and lets the loadpoint control "who wins"

However it seems that IF there is a way to set vehicle priority it would ensure the right car wins everytime.

Vehicle overwrite loadpoint - this is documented (and linked in the release notes) https://docs.evcc.io/en/docs/reference/configuration/loadpoints#priority

Yep I see that now,

Sadly I'll admit that I had that on my other screen and apparently didn't read the big blue info box...

Thanks again! This is going to be super helpful especially during the summer months!
