Sonoff SNZB-02 temp/humidity sensor disconnects

[mrneutron (Eric)]

As an FYI, I just learned of a January 2021 update to the zigbee radio firmware for the Sonoff Zigbee Bridge. The update version is ncp-uart-sw_6.7.8.
see Tasmota/tools/fw_SonoffZigbeeBridge_ezsp at development · arendst/Tasmota · GitHub

This update fixes battery drain problems with IKEA Zigbee devices.
I wonder if it will fix the disconnection of the Sonoff SNZB-02 temperature sensors?

Some caveats of the update process are mentioned in this thread.
The key to the update is to change the Module type to 75.

ZHA w/Tasmotized Sonff Bridge killing batteries with Tradfri remotes

I recently acquired a Sonoff Zigbee bridge and Tasmotized it to run ZHA and this setup seems to absolutely kill the batteries in the Tradfri remote and Tradfri On/Off switches. These switches are eating a new battery in less than 24 hours. However, if I unpair them and stick them on a Tradfri bridge, the batteries stay at 100% for several days (so far). I first noticed this issue with the Sonoff/ZHA setup with the Tradfri remotes right out of the gate - the Tradfri Bridge was just added a few …

All I did was change the Module type to (75), in the Tasmota Configuration page, and then was able to upload the new file without upload errors.
After the update, you then need to switch the Configuration back to the custom configuration (0) so it will function as a Zigbee bridge for ZHA, again.
