Motion-based (not IR) security light

[gmaz]

I want to add a security light to the back of our property but the aim of the light is directly through the exhaust flue of our gas boiler. I tried a cheap LED/solar light but it lit up every time the boiler fired up. Is there an alternative tech (microwave?) that won't be triggered by water vapour exiting the flue

Hue outdoor light with the remote sensor that is battery powered and can be positioned away from the flue?

Positioning a proper PIR sensor well above or below is I believe the only answer.

Edit, from a quick google

What are the disadvantages of a microwave sensor?
Limitations of Microwave Sensors
Potential for false alarms: Their high sensitivity can lead to false alarms triggered by minor movements, like a swaying tree branch.
Energy consumption: Microwave sensors consume more power than PIR sensors, which may impact long-term energy costs.

I found some smart bulbs on amazon with microwave detection. I have no idea what they are like though

Brilliant.




OP, we had a similar issue at a previous property and there was no effective way of moving the light, so in the end, the plumber came round and fitted a flue extension kit and this directed the outlet way up and out of sight of the PIR, so that may be an option?
