Date Format in car_charging_slots

[CTSchorsch]

Sorry for asking the next thing. I'm in a good flow with HA and predbat right now :)

Is it possbile to change the date format in the predbat_car_charging_slots attribute "planned" ?

I want to show this slot in an apex chart and without the year, it is not working. Or do i have to create a template sensore to convert the format ?

I created a template sensor, works fine for me:

• unique_id: "PredBat Car Charging Times"
  sensor:
  • name: "PredBat Char Charging Times"
    state: "{{ now() }}"
    attributes:
    times: >
    {% set times = state_attr('binary_sensor.predbat_car_charging_slot','planned') %}
    {% set ns = namespace(erg = []) %}
    {% set delta = now().date().strftime("%Y") | int %}
    {% for time in times %}
    {% set mydate = strptime(time.start,"%m-%d %H:%M:%S").replace(year=delta) %}
    {% set item = { "start": mydate | string } %}
    {% set ns.erg = ns.erg + [item] %}
    {% endfor %}
    {{ ns.erg }}

thanks for that.

I've had a look at the code and predbat uses a common function to format date/times into human readable format, that is used in lots of places across the predbat code, for export windows, car charging, battery charging, etc:

    def time_abs_str(self, minute):
        """
        Return time absolute as human string
        """
        return (self.midnight + timedelta(minutes=minute)).strftime("%m-%d %H:%M:%S")

The intent was for these to be principally human readable attributes, but I take your point they would be more processable if they are in proper date format.

But given the amount this is used, and so far you are I think the first requestor of this change, I'd be loathe to change the core code to do this.

Have instead added a note to the documentation and your template code as an example for others to follow.

thanks
