This is not a new issue, it's always been the case. Strangely, I've not found a discussion about it anywhere. The thing is that passing headlights at night, clouds or tree shadows during daytime activates all 5 of mine (not at the same time). I can't be the only one experiencing this so how have you mitigated the issue?
I don't have such at thing but maybe some kind of black "blinder" to block light coming from some of those directions?
Thank you for the suggestion but it's not light impinging on the sensor, it's light on the ground within the sensor's "view".
I have 8 of them. Same issue. On Amazon they are listed as "dusk to dawn" sensors. I assumed that meant because they had lux sensors in them. I don't think that's the reason. Fortunately my use case is security lighting after hours, except for detecting a person coming up to the front door. The front door is off the porch so it isn't a problem. If it makes you feel better I have tried a number of outdoor sensors and they all have the same limitation, more or less.
I am experimenting with using my cameras to detect people. Right now it's Arlos, but they're pretty flaky. When I migrate to PoE cameras in the spring I may stop using the Hues altogether. This will also prevent them from triggering on animals. The Arlos trigger a virtual switch via IFTTT and that drives automation, which includes turning on outdoor flood lights. If I can get it more reliable I may also have it trigger the sprinkler system. THAT should be fun.

It doesn't but good to know.
I'd dearly love to do the same but the way this house is constructed requires that I run all lines on the outside of the house which is unacceptable, especially to the cam in the far corner of the yard. I have Reolink WiFi cams and they do pretty well but the onboard motion detection was not good, for a reason I can't recall now. I've installed frigate on my server that takes all the feeds but I don't have it configured it. I have doubts that it's the answer because folks report mixed results with it.
For my front deck I use the Zone Motion Controller App's False Motion Reduction Zone to decrease false activations.
By placing one Hue sensor facing forward and one at 90 degrees to it under the railing it has been almost perfect in eliminating false positives.
No doubt this won't work in all instances (and wouldn't take long to get expen$ive) but it's been great for my use case.
