I bought 5 of the Sonoff SNZB-03 motion sensors. I paired them all to my ST hub (V3) and they were working fine at first. Then 2 of them went offline. It appeared to be a signal issue, I realized they were all communicating straight to the hub since I had paired them all right next to the hub.
Before learning that you can heal the Zigbee network by powering off the hub, I thought I would just delete the devices and pair them again.
I deleted the devices from the ST app, but then repeating the same pairing steps yielded no results. Any devices that were previously paired to the hub aren’t able to be added again. Does anyone have any ideas for pairing these sensors again? I tried removing the batteries and holding the pair button down for about 30 seconds (5 seconds puts it in pairing mode) but nothing works.
