Sonoff snzb-02 - can't control update frequency

[user3080]

Hello everybody!
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

Sonoff snzb-02 Won’t update

Hello, I am new to Hubitat, but have been using first Iris, then ST’s for a number of years. My ST’s ate crap about a week and a half ago, and I couldn’t find a local replacement. I bought my Hubitat about a year ago, and dug it out. The transition from Smartthings to habitat was surprisingly easy, and I am in the final stages of getting things back the way they were. I ordered some new temperature sensors, Sonoff snzb-02, and the install worked as expected. I can see the devices across the sys…

Sonoff snzb-02

For future readers of this thread who may be considering this device - it's a great humidity sensor - most definitely worth trying out! But... When you first get it, be VERY careful opening the cover to remove the battery tab. I broke the setting-button on my first one since the cover was on so tight and it ended up snapping the button connection when it finally popped. Just be very careful working the cover off - start with the end opposite the button and carefully work the edges around. T…

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.

even if I make the reporting every 5 minutes it does not send events every 5 minutes.

I have also tried apart from the official "Sofoff Zigbee Temperature/Humidity Sensor"
a)Zigbee - Sonoff Temperature & Humidity Sensor

b)Zigbee Reporting Configuration

with similar results even when these are selected.

I have also tried to remove and re-add the sensors with no particular luck as well.
Batteries are brand new (reporting 100%)

When seeing the events I get something like this

Any idea would be more than welcome.
Thank you in advance!

I do not have first-hand experience with it, but here is a solution from another recent thread.

Temp sensor polling times - Slow

You can try the [RELEASE] Tuya Temperature Humidity Illuminance LCD Display with a Clock driver - install the dev. branch version linked to the second post of this thread. I am able to configure the Sonoff SNZB-02 sensor to send updates as quickly as 10 seconds on 0.1 degrees Celsius change. Reconfiguring the reporting intervals and delta requires that the sensor is awake at the time when the new settings are sent to the device. You can try pressing the device pair button at the same time when…

remove and re-add

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.

@user3080 see my resent screenshot here . As @bertabcd1234 said, the easiest way to configure the reporting settings is to pair again the sensor to HE, without deleting it.

I can recommend my Tuya driver : ) - in the logs page you can see a confirmation whether the reporting configuration was successful or not :

@kkossev

pair again the sensor to HE

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.

[kkossev]

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.

@user3080

The pressing of the button does not seem to wake it up unfortunately.

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.

You can try this new version :

[RELEASE] Tuya Temperature Humidity Illuminance LCD Display with a Clock

I've been working in the last 2 days on a new major update of this driver to allow easier configuration of the temperature and humidity reporting for these devices, which support such configuration. Sonoff SNZB-02 is one of the devices which follow the standard Zigbee specifications. Once the reporting parameters for T&H are configured, click on the Save Preferences button. A new 'Current State' custom attribute will read * _info : Pending 1 (2) configurations. Wake up the device! To configure…
