Hello!

Server: RPi 4
OS: openHABian Raspbian GNU/Linux 11 (bullseye)
openHAB 4.1.1 Release Build
Zigbee binding
Popp Ember EM35x Coordinator, SiLabs Ember based NCP
Sonoff SNZB-02 Temperature and Humidity Sensor (eWeLink TH01)

I have installed 3 SNZB-02 and they are all working but when I look at the things in the UI
there are nothing to set up under “Configuration”. It’s completely empty. Is this correct?
Under "Thing Properties " two of them have 14 properties and one 19. All have “zigbee_device_initialised” = true.
Are they still not fully initialised?

Thanks for help.

Yes, it’s basically correct. You will only see the MAC address and an option to reinitialise in the configuration.

I have many of these and they have been working well. Can I ask what configuration you are expecting to see in the configuration? Currently there is none, and on this sort of device there’s not a lot to control. We could of course provide configuration of things like reporting parameters, but since this is a battery device it can be problematic to change configuration within these devices.

Thanks Chris

Mine works fine too, but in frontail I can see that they send reports at 10s to 20s intervals where the temperature has only changed by 0.08 to 0.14 °C.
What I would like to be able to do is specify the threshold change of temperature/humidity to send a report.

Do you have any possible explanation about the "Thing Properties ".

Currently it’s not possible to change the reporting. Normally these devices should report every 10 to 20 minutes (at least all mine do). Changing reporting on battery devices is problematic since they sleep, and for that reason it’s not implemented. This could easily be made configurable, but you’d need to wake the devices at the time you make the changes.

Many of the thing properties are internal information that the binding uses. There are a lot of them and some should be self explanatory, and others are probably not of interest. If you have some that you want to know about, please let me know and I’ll try and answer, but there is currently no list.
