Is it possible to update Sonoff sensors like the snzb-02 or the SNZB-02D? Are there newer firmware versions?

You might want to let people know what your current firmware version of these sensors is.

BTW:
The only Sonoff device that shows up with a ‘Check for new updates’ button in my Zigbee2MQTT dashboard is the Sonoff SWV, but then again: I don’t have an SNZB-02.

Hello,

I’ve got some SNZB-02D (all with 1.09 firmware version) and many of them have an issue for months. They are not reporting their values (through z2m).
Today, I was looking for firmware updates and found this : https://forum.ewelink.cc/t/sonoff-snzb-02d-update-fails/101372
So, they have published a new firmware but I don’t know how to get it without a eWeLink gateway.
