HowTo Deep Sleep?

[baal86]

Hello,

I am playing around with deep sleep but can't get it to work. I have an H2 board and a C6 board. Esphome does not support deep sleep on the H2 so I am using the C6. I have a naive config with just a temperature sensor and a fake pressure sensor that increments on button press. The code below (without deep sleep) works great! If I add a basic deep sleep statement with 1s on time and 10s off time, the device gets stuck at boot. I will need to hold BOOT and reprogram it to get it back to life.

Anyone has experience with deep sleep and zigbee? My final application only needs to send one sensor value every 10 minutes or so and I'd like tp spend the time inbetween sleeping to be maybe able to run from battery

I did not test deepsleep (and I have only a H2, so someone needs to add a PR for adding this first).
I would expect it to just work, but maybe I need to block deepsleep during zigbee setup.

Anyway, deepsleep is not really ideal for zigbee because it needs to connect to the network each time which takes much longer than 1s, I guess. Lightsleep would be much better, but is not supported by esphome.
Try to set on time to 1 minute and if that works try to reduce it.

[baal86]

Yes, I am aware of H2 not being fully supported at the moment. I raised the issue there. If I can get my head around the esphome build system and dust off my C++ I'll fix it myself and then submit it as a patch.

I'll continue experimenting with Zigbee + deep sleep on C6 then. (starting with confirming the C6 deep sleep actually works!) I had hoped someone had already tried it with this component.

Got something working. It will wake up every minute and send data for 10s. I discovered that if I force report zigbee I can get quite a few samples out in that 10s period. I have made a GPIO wakeup as well that gives a minute so that zigbee configuration works. All of it implemented on the C6. Now need to look into the H2 or hope for the maintainers to get to it. I think I will underclock the C6 and see what power consumption I get there.

FYI: Started tinkering with the deep sleep feature of the H2. https://github.com/baal86/esphome/ It does not have GPIO wakeup so the external pin wakeup needs to be implemented using EXT1

[luar123]

Interesting, I thought you could just re-use the implementation of C6.

[baal86]

Got it running. Pull request ongoing at esphome. The H2 is impressive. With Zigbee active, current consumption is around 10-15mA. When in deep sleep not measurable (with the stuff I have at home at least..). I can very reliably get samples out with just 10s wake time.
