I was getting false triggers with my Aeon Labs MultiSensor outdoors. I tried reducing the sensitivity down to the very minimum and was still getting the issue.
I took matters into my own hands and gave my sensor some eye lids.
It’s pretty simple to open up and this reduce the false triggers caused by the IR pickup from the sky.
I took a small piece of paper and taped it to the inside of the sensor cover. So far it still picks up motion from my patio and has yet to give me false triggers. I’ll test this more in next few days and make adjustments as necessary.
