@Milk The drops in connection are getting worse, but the WIFI and Zigbee on the panel itself seem to be ok. A restart of the NSPro will restore everything instantly. I just found this posting here(NSPanel Pro 4.3.0: Zigbee stack becomes unstable, devices randomly go offline and MQTT bridge stops working); the problem I described here for 4.4 seems to be old and not yet resolved.
