Automation help - Timer for light switch

Hi all, I’m having an issue with an automation. It should be simple, but it’s not working for me through the GUI or raw yaml, so obviously I’m missing something. I’m trying to set a timer on some switches (hallways and closets) so that they’ll turn off 10 min after being turned on. They’re Zooz switches implemented through OZW.

Here’s the code I have (note, it’s set for 30 seconds for testing).

alias: Basement stairs light timer
description: Turns off basement stairway light after 10 min
  - platform: state
    entity_id: light.basement_stairs
    to: 'On'
    for: '0:00:30'
  - service: light.turn_off
    entity_id: light.basement_stairs
mode: single

What am I missing/doing wrong? Any help? I’ve tried various formats under the for: attribute, from 00:00:30 to 0:30 to “seconds: 30”, etc… None work. Everything else “should” be valid. I’ve confirmed that the light updates the state immediately and that light.turn_off is working with the light, so that pretty much leaves the timer or a formatting error, right?

Any help?

Try low cap on.

to: 'on'

Got dangit gump, you’re a genius. Stupid typo’s,and the yaml editor turning that line green made it near impossible to read/catch.

Thank you!
