NS pro loosing ZigBee connection

Does anyone else loose some ZigBee connections with their NSPro panel. A reboot fixes it but I need to do this every 4 to 5 days

I’m afraid that without details about how your Zigbee network is set up, it’s impossible to say anything useful. Make an effort and describe which Zigbee devices are connected to your NSPanel Pro and how they’re distributed throughout your apartment. You don’t expect anyone to make intelligent guesses, do you?
