Made this, think it works, it will only use price for tomorrow if valid:
{% if state_attr('nordpool_kwh_dk1_dkk_2_095_025', 'tomorrow') == none %}
{% set interval_end_tomorrow = 0 -%}
{% set interval_end_hour = 23 -%}
{% else %}
{% set interval_end_tomorrow = 1 -%}
{% set interval_end_hour = states('input_number.mini_charger_ready_tomorrow') | int -%}
And the use a helper to set the time when it must be ready to morrow (made in configuration.yaml)
input_number:
mini_charger_ready_tomorrow:
name: Mini klar kl
icon: mdi:clock-check
mode: slider
initial: 7
step: 1
min: 5
max: 23
unit_of_measurement: Kl
I also created a automation there starts the charger when power is under a certan cheap price, and sends a notify if the car is home and not plugedin. This automation waits 55 minutes if second car is low (under 70%). We have 2 EV car’s one with 33kWh and one with 89kWh battery and loadbalancing on the chargers. 1 car chargning = 11kW, 2 cars 5.5kW each
alias: EV MUSTANG - kWh < "input_number.ev_charge_start_always" kr start ladning.

So when the car is plugedin the script puts the charger into pause if it has not been told to charge from the “EV MUSTANG - kWh < “input_number.ev_charge_start_always” kr start ladning” (by using a helper to keep track of charge on or off
and then eletricity prices gets above helper value it stops charge and sends notification:

The above makes sure that when electrity is cheap we charge, no matter what nedded
Now I have also made some template sensors that constant gives me these information:
Those are I planing to use from automation
in pseudocode:
if mustang < AA% and kWh awg price is < xx charge to BB%
if mustang < CC% and kWh awg price is < yy charge to DD%
if mustang < EE% and kWh awg price is < zz charge to EE%
Next look into my calender to morrow and se how far do I have to go and then make sure there is enough power for that (I work out from home)
So basicly I want to charge, under these conditions:
CAR 1:
!. Eletricity price cheap
2. If not enough charge for what I have to drive to morrow
CAR 2:
!. Eletricity price cheap
2. If not enough charge for what I have to drive to morrow
Also needs to think in load sharing in the Easee charger if both have to charge same day…
So I have a long way to go yet:-)
and learning my self on how to (also new to HA)
