Automation trigger from '0' to above 200

I’m monitoring my UPS in HA and have an automation to trigger if voltage is below 1 volt (power outage).
It looks like this:

- alias: 'IT - UPS strøm (fra)'
  trigger:
    - platform: numeric_state
      entity_id: sensor.nut_ups_input_voltage
      below: 1
  action:
   ...

I would like one to trigger when sensor.nut_ups_input_voltage changes from 0 to above 200 (power is back), but unsure how to do it. I know it can be done with a sensor template and monitor the sensor in an automation, but it seems like overkill.
Any advice?

Just to clarify, do you only want it to trigger when the value was 0 and is now above 200? So if the voltage was at 2 then jumped above 200 you wouldn’t want the automation to trigger?

If the previous value isn’t important and you only want to know when the value goes back above 200 just use “above: 200” instead of “below:1” in your trigger.

Yes. But a value above 1 would also work.
The automation triggers on HA bootup if I only use above: 200 in an automation.

To avoid that set the automation to initial_state: off so when Home Assistant restarts it will be off. Then use this automation to turn it on after the sensor’s value has been set.

- alias: 'HASS Starting'
  trigger:
    platform: homeassistant
    event: start
  action:
    - delay:
        seconds: 10
    - service: automation.turn_on
      entity_id: automation.YOUR AUTOMATION NAME
