No issues at all so far. I bought one of the hue floodlights which the sensor is controlling. The setup is really good but you do need to use custom commands to get full decent brightness out of the light - just using the He standard dimmer options for temperature and colour don’t yield great results.
My only issue with the dimmer is that it isn’t heat activated the same way indoor hue sensors are; as in, normal pir heat + motion being required for the sensor to see motion. It’s a good thing and bad thing. Good because it reacts much quicker but bad if you have something flapping in the garden! I have bikes under a bike cover and where the winds have been bad the last few days the light is being triggered a lot. However, the distance the sensor works over is phenomenal! The bike covers are a good 20m away from the sensor and off to one side of the garden.
Amazon UK is where I got the sensor from and it’s definitely worth it’s money. I believe this is the first true outdoor smart sensor that incorporates lux and thankfully it does work very well
