I also tried to connect to the SONOFF Zigbee Bridge Pro by myself, but with no success…
I have a feeling that the SNZB-05P went into some mode…
I tried holding the reset button for more than 5 seconds, pressing the reset button 5 times in a row, etc. Unfortunately, nothing resulted.
Although both SNZB-05P, which I have, behave the same… So they won’t connect to eWelink, while they connect to HA without problems and work flawlessly.
In nspanel pro start adding devices. on the sensor under the battery cover Press the button for 10 seconds. the device will go into pairing mode. the red diode should blink.
I have a feeling that the protocol between SNZB-05P and NSPanel is not harmonized…
When I start pairing, after pressing reset 10 s on the SNZB-5P, the red LED begins to change its state slightly (turning on and off), like this 5-6 times, then stops (remains lit), after which it changes its state again 5-6 times and he stops and so on in a circle
