I find the floodlight to be very inconsistent.
I have PIR off because its very sensitive in rain/snow and only have it on when it detects motion. Many of times it has detected motion, sent me an event on it but the floodlight never turned on. I had a fox on our patio, it recognized the motion and event but light never turned on. Sensitivity i think was 60%. Thats usually enough to trigger the light.
Your floodlight might have a hardware issue…
Mine never turned on because of PIR sensor being triggered by rain/snow. It would turn on because the camera’s infrared light (for night vision) reflects off the rain/snow. Since I turned off night vision, relying only on starlight sensor, it hasn’t been triggered by rain/snow.
As for floodlight not triggered by motion event, that might be a platform issue. To workaround this, you can create a rule to turn the floodlight on for x minutes when the camera detects motion, and that works for me every time.
Just to clarify, I did have my floodlight turn on during the cooldown period one time, so it is very inconsistent for me too.
