Just bought a few cams because of the rstp beta. Firmware flashing went perfectly. Cameras setup in the wyzecam ios beta app. Cams added to a Synology nas. During an ISP outage RSTP functions fine and recordings show up on the nas. If the camera is power cycled RSTP doesn’t work until access to the internet is restored. (the cam associates to WiFi and picks up a local ip during outages).
