I am relatively new to the habitat ecosystem and I try to figure out some stuff.
I have 7 Sonoff temperature sensors, which I have successfully set up.
but their reporting frequency is very rare.
I have read similar topics
but I haven't manage to make it report on the resolution that I want.
Typically it sends 1-4 readings per hour (most usualy 1 per hour).
The settings are set to be 0.25C , which is not respected. I usually get 0.5C intervals or more.
Try re-pairing but without removing the sensor first.
Unlike many battery-powered Zigbee devices, the Sonoff Zigbee sensors appear to "fully" sleep and are not responsive to commands from the hub (configuration, refresh, etc.) unless they are awake at that moment. From one of the threads linked to above, it seems that pressing the button on the device might wake it (so you can try that around the same time as a Save Preferences or Configure), but re-pairing is another way to make that happen since Configure will run then, too, and they are definitely awake when pairing.
Re-pairing should also give you a clear indication in the UI that the device was re-discovered (instead of needing to guess whether it was awake and the configuration worked). With Zigbee devices, unlike Z-Wave, they'll fall right back into place after a reset/re-pair as long as you don't delete them first--one reason I say not to remove it first, besides the fact that your settings will be there configured how you want, which they won't be if paired like new.
Thank you for your answer after digging in a bit I think that is what happens, the configuration never gets into the device since it is in a deep sleep mode.
I don't have very clear how could I trigger a "re-pairing". The pressing of the button does not seem to wake it up unfortunately.
Go to Devices -> Add Device -> Zigbee -> Start Zigbee Pairing.
Press and hold the device button for 4..5 seconds until the LED starts blinking. The sensor should pair again to HE as a previously found device.
You are correct, I have edited my previous post for this device only, Other devices will wake up by pressing the pairing button, but SNZB-02 will not.
Another trick to successfully send the reporting configuration to deeply sleeping Zigbee devices is to click on the 'Save Preferences' button a second later after you remove and insert the battery cell back into the sensor.
