Zigbee sensor reporting intervals

[summongod]

Will Tasmota support changing the interval period or sensitivity for sensors such as the Sonoff SNZB-02?
At the moment I get a lot of activity due to the sensitivity of the humidity readings and I'm concerned that it will drain the battery.
I have seen this thread Koenkk/zigbee2mqtt#3794 in Zigbee2mqtt and before the change was accepted I made the changes suggested to reduce humidity reporting on my Sonoffs when using ZbBridge with Zigbee2mqtt and it appeared to work as expected.

What is the frequency of reporting? Can you share logs of consecutive readings?

Thanks. It seems to follow the Zigbee standard, which means you can ask the device to report between min and max interval in seconds or whenever a change exceeds x in value.

As you can see in the logs, you have an example of syntax:

20:01:41.098 ZIG: auto-bind `ZbSend {"Device":"0x540C","Config":{"Temperature":{"MinInterval":30,"MaxInterval":3600,"ReportableChange":0.2}}}`

In the example above, ZbSend {"Device":"0x540C","Config":{"Temperature":{"MinInterval":30,"MaxInterval":3600,"ReportableChange":0.2}}}sets the following:

• don't report faster than every 30 seconds
• always report at least one per hour (3600 seconds)
• report when temperature changes by 0.2 degrees (which happened in your logs as temp dropped)

I understand, but there are too many values to put them all as #defines. I picked values that seemed reasonable but I'm ready to revisit them.

We can also move to #define some of them.

Are only the threshold you want to change?

I see the challenge, perhaps you could have different default settings based upon PowerDescriptor, more conservative for battery powered and less for mains powered?
In my case it was the humidity sensor that was changing quite often so I would change that if anything. Personally I don't think that this sort of sensor requires a huge amount of accuracy but I am sure that others who like graphs that are smoother will disagree.

I proposed some constants in my_user_config.h in the latest PR, see #10498

I just compiled for ESP32 with a CC2530 and I can confirm that the #defines work as expected. Thanks for doing this.

Thanks for the confirmation
