ok, read the set up instructions and got my sentinels connected to the xyp app and they show up in coin. Brdige is plugged into the net and supposedly working. Question I have is do I need to marry the Sentinels to the bridge, same as I did with xyfindit?
No, on the bridge it should show your sentinels in Nearby Devices. Click on Nearby Devices and it will show your sentinels as XY4+ devices.
