Zigbee Implementation: Deep Sleep example

[HiFiJ]

Related area

Zigbee

Hardware specification

ESP32-C6

Is your feature request related to a problem?

Hi,
thanks for the tremendous and fast implementation and merge of the Zigbee library!

I am wondering if there is already an easy way at this point to set up a battery powered ESP32(-C6) endpoint utilising deep sleep?

Or are there higher obstacles to pass to realize deep sleep/short wake up times for e.g. sending sensor readings?

Thanks again very much, best regards,
Joost

Describe the solution you'd like

Perhaps one of the examples could be enhanced slightly to include deep sleep with periodic wake up.

Describe alternatives you've considered

Hi @HiFiJ, I will get to add more stuff to Zigbee library later as now I have different important tasks. So I will link this feature request to the original issue of Zigbee library support, and once I get to the Zigbee library again, I will investigate this :)

There are by the way already Zigbee examples of "deep sleep" and "light sleep" (standby) modes for sleepy Zigbee End Device in the esp32-zigbee-sdk repository which could probably used by this new API(?). See:

• https://github.com/espressif/esp-zigbee-sdk/tree/main/examples
  • https://github.com/espressif/esp-zigbee-sdk/tree/main/examples/esp_zigbee_sleep

    • https://github.com/espressif/esp-zigbee-sdk/tree/main/examples/esp_zigbee_sleep/light_sleep

PS: I recently also read that Arduino has released an open-source Arduino Power Management library for Arduino Pro that could maybe be ported to arduino-esp32 for ESP32? It includes battery management and charger manager + sleep and standby mode:

• https://github.com/arduino-libraries/Arduino_PowerManagement/
  • https://github.com/arduino-libraries/Arduino_PowerManagement/tree/main/examples

More on that new Arduino PowerManagement library here:

I was investigating this and we don't have Power Management or ULP Core enabled in the sdkconfig we use to build the libs.
There is more work to be done before supporting that. I will keep this issue updated if there are som ongoing tasks :)

Thanks very much for taking a closer look!
From a hobbyist's perspective, I believe that there is great potential for this Zigbee stack to be the first to enable useful battery powered devices with wireless signal transmitting for DIYers/amateurs.
At least I have been looking for easy ways to accomplish this for years (MySensors project etc...) without finding a viable alternative and also have read several times of other hobbyists struggles to achieve this.
A lot of people are looking forward for this to happen :-)
Best regards, Joost

I will be doing some testing in upcoming days to see what we can do with power consumption for Zigbee. The deep_sleep may be possible without a need of changing the core libs configuration. Will keep you updated :)

Hi,
thanks a lot for your tremendous work!
I am absolutely looking forward to try/use this, great choice of clusters as well.
I wil just have to wait until this ends up in an arduino-esp32, as I do not have the necessary knowledge to switch to your branch.

Thanks again! Best regards,

Joost
