Today I tried pairing a new device but it didn't work anymore.
When I unplug the Aeotec Z-Stick gen5 and push the button to pair it blink blue one time and then red one time and then it stops, nothing happens anymore. When plugin it back into the USB port domoticz is working like it should. But no new device is found.
Aeotec Z-Stick gen5 is 1 month old.
What is wrong with my Aeotec Z-Stick gen5 USB stick?

Regards,
