Automation repeat index not working + how to message when in normal state?

Configuration
1

I am using this automation to tell me when my UPS is on battery power. UPS is plugged into a smart plug.

Why doesn’t the max repeat index work? I have also tried this condition above the delay. And how do i make it so that when the power is above 50 for 1 minute after not being above 50 i get a different Telegram message? Can this be done in the same automation?

This Template Condition, located at the end of the repeat’s sequence, serves no purpose.

        - condition: template
          value_template: "{{ repeat.index > 10 }}"

You want it to be part of until’s condition, logically ORed with the existing Numeric Device Condition.

  - repeat:
      until:
        or: 
          - type: is_power
            condition: device
            device_id: ee631307bf6eb386910378dad949ac1c
            entity_id: 308b990b8da06b90e05632fa9032d0f5
            domain: sensor
            above: 50
          - condition: template
            value_template: "{{ repeat.index > 10 }}"
      sequence:

I suggest you use a separate automation.
