They’re two separate schedules, yeah. Since I don’t know what schedule you set or where you set it, I asked for more detail in the topic you created.
If you just want the lights to turn on and off on a schedule regardless of what the camera is seeing at a given time, then yes. You could also do this with Schedule-type Automations, but the Ambient Light feature is built into the device’s settings and gives you control over the light level, which I don’t believe Automations currently allow for this product.
That’s for motion-activated light. Notice on the “Bulb Settings” screen it’s under ACTIVATE WHEN. When you tap on Motion, you get to another “Bulb Settings” screen with a Motion toggle. If you tap the information circle icon, the app explains more about how this feature uses motion to trigger the lights, and you can set the lights to trigger on motion based on All Motion events or (with a subscription) Smart Detections. The schedule you set on this screen determines when the motion-activated lighting feature will trigger. If you go back one screen to the previous “Bulb Settings” screen and set the BRIGHTNESS LEVEL slider, then that determines how bright the lights will be when they’re triggered by motion.
