Hue motion sensor problem

Hi Guys,

I have multiple hue motion sensors connected to zigbee dimmerswitches. In general they work well, but lets say 1 out of 5/10 times the hue motion sensor triggers the lights to switch on, but they switch on completely dimmed. So it looks like the sensor doesn’t bc the lights stay off, but actually the lights are on but on 0%. Did anyone see this problem before?
