@Milk : as also described in Tickets have no reply - #3 by vpolizzi , I have frequent issues with the Wifi connections lost. Other wifi decives have no issues (e.g. NSP non pro panels) and other smart home devices. What can be the issue? If i restart (cold restart via a switchable socket) the NSPro it might work for 10 min or a day until it looses the connection until the next tap on the screen and if unsucessfull reboot. What could it be? With the 4.4.6 Zigbee seems much mor stable and my device remains connected (unless the NSPro losses wifi connection of course).
best
