HomeKit Automation not working properly

Hello all! First time posting here.

So I’ve just started using HomeKit automations & I’ve started out with some simple ones. But they aren’t working 100%

I have a time based automation where when my front door camera detects motion between 8pm and 7am, my porch light will turn on. After 1 minute, it will turn back off. All that works great, except that after 1 minute is up, it’ll turn off, but then turn back on again. It’ll keep going like that unless I shut off my the light manually from the Home app. Is there something I’m doing wrong here?

Thanks!
