Add support for showing entity output for secondary_info

[andreas-bulling]

Various pre-defined information can be shown in secondary_info but what does not seem to be possible is to show values/states of an entity or template sensor - in my case the charging state of a battery. When I put sensor.battery_status for secondary_info it shows that exact string instead of the status itself.

When I put sensor.battery_status for secondary_info it shows that exact string instead of the status itself.

Post a SHORT code with your attempt to show a state in the secondary_info.

This is the template sensor (battery_status):

{% if states('sensor.victron_vebus_battery_current_227') | float < 0 %}
  Discharging
{% elif states('sensor.victron_vebus_battery_current_227') | float > 0 %}
  Charging
{% else %}
  Standby
{% endif %}

And this is the bit in the frontend

type: vertical-stack
cards:
  - type: custom:multiple-entity-row
    name: Battery
    entity: sensor.victron_battery_soc
    show_state: false
    state_color: true
    secondary_info: sensor.battery_status
    entities:
      - entity: sensor.victron_vebus_battery_current_227
        name: Current
        format: precision1
        styles:
          font-size: 20px
      - entity: sensor.victron_battery_voltage
        name: Voltage
        format: precision2
        styles:
          font-size: 20px
      - entity: sensor.victron_battery_soc
        name: SOC
        format: precision1
        styles:
          font-size: 20px

Your code does not show a state in secondary_info because this part is wrong. Check docs.

secondary_info:
  entity: sensor.battery_status

Suggest to ask similar questions in the dedicated community thread and leave GitHub for reporting bugs and proposing FRs.

Thanks for the hint. I did go through the documentation in detail and tried many things. After I failed I thought it might be a bug and opened the issue. Maybe an example for how to use an entity this way would help.
