what sensor is this: sensor.pv_to_ev_power

See above from line 150. That is just a helper to calculate available power.
It looks at currente charge rate and the export and a bit of rounding.
If you are charging with 6kW and exporting 4kW you have 10kW available for charging.

The reason i've done it that way is that it was easy to add statistics sensors that looks at 2 and 10 min averages as welle as minimum.

I use those to decide when its time to change between 1 and 3 phase charging. In the above i will first change to 3 fase when the minum surplus has been over 3680W for 10 minutes. The other way it will first drop down to 1 phase again when the average has been below 3680W for 10minutes.

So on a day with many clous the min drop often and it will stay on one phase charging..

On a good sunny day it will stay on 3 phase even troug i use a lot of power for a short while for i.e a cup of coffe (if its get below 6A it will pause for a while)

Ive had to change time to live to 0.

Don't know if it is a change in the HA integration og an easee api change, but it seems that if the values are not changed in HA it will not get trough and go back to default after the minute specified
