Security lights not detecting motion

Security lights are connected to the arlo lights bridge, I can see them online in the app, but will not detect motion. I can manually turn on the light from the app, but they will not turn on automatically when motion should be detected.

Are there rules for the lights in the modes you are using?

Which mode is this affecting, I see you only have rules for it to send a push notification in the Arm away mode when motion is detected.

You can try adjusting the sensitivity as well, per this article: https://kb.arlo.com/000062052

The Home mode is the one that is active. I have my cameras and now the security lights added to that mode. Now another problem has arisen. The security lights now come on, but during the day. How do I get them to only turn on during the night? I created an automation and put one light in to test. But it is not night yet, so gotta wait on that one. If I set the security light to come on at sunset, it will only come on when motion is detected correct? This whole problem started with app update, never had any problems before. Please let the progamng team know so they can to address this. Please file this as a official complaint. Before the update I could add a security light and it would just come on at dark, easy peasy. Why should I have to go throught so many steps just to get a light to work?

Also, I forgot tomention they come on when motion is detected, during the day also. I also lowered the sensitivity on the security lights. That did not help.

To prevent your security lights from turning on during the day, you'll need to adjust the Dusk to Dawn Sensor setting:

Launch the Arlo Secure App or log in to my.arlo.com
Tap or click Settings > My Devices
Select your Arlo Security Light
Tap or click Light Settings > Dusk to Dawn Sensor
Move the slider toward the left ("Dark") this ensures your light only turns on when motion is detected and it's dark enough outside

By default, the ambient light sensor measures the brightness of the light's surroundings and determines whether the light should activate when motion is detected. If it's bright outside, the light won't turn on, but you'll still receive motion detection notifications.
