Right now, my flood light is not turning on at night when motion is detected even when I set everything to be on in the setting. Reading a coupe of Reddit and community posts, the issue appears to be the streetlights or any kind of external ambient lights trick the light sensor, thinking that it is still daytime and no lights are needed.
So can EUFY please add a schedule setting (ie. sunset to sunrise) in the “Motion Activating illumination” setting so it forces the lights to turn on no matter how bright the ambient lights are? I think it will fix the issue temporarily when you guys figure this thing out.

I’m having the same issue. It’s so frustrating. The Eufy 2K floodlight has similar issue. They haven’t fix it yet. Only workaround.

I have the same issue, i am more than interested if anyone has a working workaround.
Is there a light sensor or is this done by the camera ? it should me easy to cover a light sensor but covering the camera would be stupid 
I am having the same issue the floodlight has only worked once with motion detection due the ambient lighting where the camera is located.
Looks like other are having the same issue https://www.reddit.com/r/EufyCam/comments/185ip0d/flood_light_e340_motion_activated_floodlight_not/Flood

So we have floodlights with lights never going on…

If there is a light sensor, it’s probably behind the motion sensor component cover lens.
Shine a bright flashlight on the cover lens, it should be a bit transparent to see if you can spot the light sensor.
I got a firmware update yesterday and so the lights of my E340 for the first time in the evening, seems way better for me !
I just bought this light and it was working and then the firmware was updated and now the floodlight doesn’t work at all. is there a way to reset the light to go back to factory settings?
I was experiencing the same issue initally, top light was never on, but then found out accidentally, that it’s working when video settings set to Colour Night Vision. So, now I have both lights on at night time along with beautiful colour night vision picture
You’re absolutely right about the potential issue with ambient light affecting your floodlight’s motion sensor. The presence of streetlights or other external lights can indeed trick the sensor into thinking it’s still daylight, preventing the light from turning on when motion is detected.
Your suggestion to add a schedule setting (like sunset to Tierbestattungen Albstadt) in the “Motion Activating illumination” settings is a practical workaround that could help address the problem. By allowing the lights to turn on regardless of the ambient light level during specific hours, you can ensure that your floodlight functions as intended during the night.
To address this with EUFY, you could reach out to their support team or post the suggestion in their community forums, where other users can support your idea. If enough users request it, the development team might consider adding this feature in a future update.
Has anyone been able to find a solution for why the floodlights do not work? I just bought mine and set it up and lights do not work even if I cover the sensors.
