Request: decimal place configuration about tesla-style-solar-power-card

[djfanatix]

Yes one up for this!
Since HA 2023.3, decimals are configured in the UI, and some are messed up. (such as my battery %)

That would be nice. It would save having duplicate template sensors.

I figured out something that works for me - rounding the APF xxxx Entities to the nearest 100 Watts. In the card, the entity is then shown as an integer when it is watts, and to 1 decimal place when it is kilowatts (and maintains the trimming of the trailing zero, like the grid entity shown below). You could similarly round to 10 Watts or 1000 Watts for different levels of decimal precision.
e.g. For the APF House Entity:
state: "{{ (states('sensor.load')|float / 100)|round(0) * 100 }}"

Would still be handy to do it via the config, but this also works.

@melvanderwal I hope you're still watching this thread. Could you please do me a huge favor and copy and paste all your template sensors related to tesla-style-solar-power-card as
tesla-style-solar-power-card lovelace code?

I think something must have changed in Home Assistant or the Integration to make your example not correct anymore. When I use your example above, all my AFP values show as 0. It looks like your suggested code is presuming that my tesla powerwall Entities are in Watts. They are actually in Kilowatts for me.

Below are my template sensors:

      - name: APF Grid Entity
        device_class: power
        state_class: measurement
        unit_of_measurement: W
        state: "{{ ((0 - states('sensor.powerwall_site_power')|float * 1000) / 100)|round(0) * 100 }}"
      - name: APF House Entity
        device_class: power
        state_class: measurement
        unit_of_measurement: W
        state: "{{ (states('sensor.powerwall_load_power')|float * 1000 / 100)|round(0) * 100 }}"
      - name: APF Generation Entity
        device_class: power
        state_class: measurement
        unit_of_measurement: W
        state: "{{ (states('sensor.powerwall_solar_power')|float * 1000 / 100)|round(0) * 100 }}"
      - name: APF Battery Entity
        device_class: power
        state_class: measurement
        unit_of_measurement: W
        state: "{{ ((0 - states('sensor.powerwall_battery_power')|float * 1000) / 100)|round(0) * 100 }}"
      - name: APF Grid Import
        device_class: power
        state_class: measurement
        unit_of_measurement: W
        state: >
          {% if states('sensor.apf_grid_entity')|int(default=0) < 0 %}
            {{ states('sensor.apf_grid_entity')|int(default=0)|abs }}
          {% else %}
            0
          {% endif %}
