I had bought new HE C-8, complete hook it up now using ethernet connection. But I have already took me hours and still cannot add the device SNZB-02 Temperature sensor to HE C8. Pressed reset button for 5 secs, the zigbee blinked 3 times, HE managed to find the device but fail at initialization. It recommended pairing using legacy method but also not working.
tried reset
tried changing new battery for the device
tried restarted the HE
tried looking for answer from FAQ and some other postings,
all the above does not solve this add device issue with Sonoff SNZB-02. My HE is running version 2.3.5.125, gave up to update to version .146. ( I have managed to update to 2.3.5.146 on 4th June 2023)
Could you refer me to a guide how to install the driver in the link referred. There is no usb or com port on the SNZB02, how do we do that. I tried searching in the youtube, couldn’t find anyone making the video how to do it
This device is a bit twitchy to get initialized, for me it wouldn't even try joining on channel 18, but did on channel 11.
The inbuilt driver works fine with this device.
I followed the directions that came with the sensor.
Basically, long press reset button on the device for 5s until the LED indicator flashes three times, which means the device has entered the pairing mode, and be patient until pairing completes.
I start with installing the driver from On La Labs, after that I went left menu, Device , +add device, zigbee sonoff temp sensor. I have got still the same error. The following pictures to illustrate what steps were taken:
I took the step to "rebuild network"in the Zigbee menu. reset the sensor and start pairing with the HE. The issue of not able to complete the initialization still happened after rebuild network. I tried twice resetting the sensor. The status as per below snapshot:
If you have not already tried this... after it fails, try resetting the devices following manufacturer's instructions while your hub is NOT in pairing mode.
After the device reset, try pairing again.
When my zigbee radio has a higher power level than 8, I find these battery powered devices are harder to pair and don't stay paired. With power level at 8 and repeaters like GE Enbrighten in wall switches, Tuya repeaters, and Tradfi outlets, batter powered devices pair properly in place and stay connected.
I tried using power level 8, but also it's not successful in initializing.
I have tried many approaches:
Tried using drivers from Oh LA Labs,
Tried installing the KKOSEV drivers just incase it might work with the SNZB02
Tried rebuild the network in the zigbee setting
Tried changing the channel to 11 (from 20) and power level to 8 (from 16)
-Tried the resetting prior the pairing 1st
Tried the "Pairing in exchange keys in clear mode"
All the above unable to address the issue the device stuck at initialization, I tried all of my 4 SNZB02 Temp sensors, they are having the same initialization issue.
