Aqara Temperature & Humidity sensor - very chatty on logs (10+ repeated updates in a second)

[techie-dreamer]

Hi all,
Related to my Zigbee controller freezing issue I've been slowly reintroducing 'spamming' temperature sensors and trying to re-adjust them so the are less 'chatty'.

But, the Aqara branded temperature / humidity sensor ( which reports as Tuya TT001ZAV20
) keeps sending repeated commands of same data.

This is typical avery 5 minutes:

How do I get it to stop sending so many reports?

Thank you!

Have you tried debounce?

[MSL-DA]

Have you read the documentation?

debounce
Debounces messages of this device. When setting e.g. debounce: 1 and a message from a device is received, Zigbee2MQTT will not immediately publish this message. But it will combine it with other messages that are received max 1 seconds apart from each other. So there needs to be "N second of silence" from the device before the combined message is sent out.

For example debounce: 5 means that there needs to be "5 seconds of silence" from the device, before combined messages is sent out.

This is handy for e.g. the WSDCGQ11LM which publishes humidity, temperature and pressure at the same time but as 3 different messages.

Don't configure debounce to be higher that sensors update interval as that would cause all the messages to be debouncer and messages won't be sent out at all.

[sphings79]

Have you tried debounce?

I saw that option but would that just reduce the payloads being sent to z2mqtt? Therefore not actually reduce messages sent by device & still cause the lock-up issues on the controller?

If not, what value do you suggest for debounce?

Sorry, missunderstand your question

Sorry, missunderstand your question

No need to apologise, I did read the docs ( @MSL-DA ) but not sure if it would help my situation.

I don't know, in fact I don't understand that there are so many problems with SMLIGHT. I have 11 of these units WSDCGQ12LM and 2 WSDCGQ11LM

Regardless of the firmware I've used, I haven't experienced these issues. Now I updated to dev26 and when I did that my SLZB-06M was online for 8 days (dev16)

I know, it's very confusing as per this thread I've had 7 temperature sensors working fine with same smlight controller for 6+ months and only now it's an issue.

Removing batteries from all temperature sensors seems to stop the co-ordinator crashing (been about 6 days now), so it's obviusly the reason but I'm still unsure of the technical cause still (is it really spamming? as they have had same settings for ages). Maybe it's something in the z2mqtt software as this has been updated many times in last 6 months?

It's a real struggle to unpick what's wrong but for now, I'm pleased my lights are working (even if the temp sensors aren't connected).

I had this spamming behaviour with temperature sensor tuya WSD500A.
I change batteries for new good ones and the problem had disappeared.
Hope it can help

Thanks for this - I have 7 devices and all exhibited this behaviour - new batteries (tested voltage too) have been added - no change.
