PROBLEM DESCRIPTION

Can't enable DeepSleep for use with Timers on an ESP32-S3-CAM devkit board. I don't know if I need to connect a wakup pin to the RST pin as described in the docs where GPIO 16 is connected to the RST pin for ESP8266 devices.
The ESP32-S3 board I am using has GPIO 16 connected to the camera data, so I can't also use it for deepsleep self-wakeup.
See board pinout below.

Not applicable.

TO REPRODUCE

Steps to reproduce the behavior:
Setup DeepSleep Rules and Timers in Web-GUI as per the Docs. I need to know which GPIO pin to use on this board for the wakeup signal.

To quote myself from Discord:

Doing a simple test with a very similar ESP32-S3 camera board, I used no pin config. With the command DeepSleepTime 120 it woke every 2 minutes, with a brief uptime (from boot to sleep) of approximately 13 seconds. This includes all the usual boot stuff like WiFi, NTP and MQTT. And a short countdown before hitting the pillow. Conclusion: No pin is needed for self-wakeup as such.

After some testing:
I can confirm that using something like DeepSleepTime 60 does work as expected, wakes up after 60 seconds of deepsleep, does a teleperiod, goes back to sleep for 60 seconds.

Using restart 9 does NOT put the board to sleep as expected. With DeepSleepTime set to 0, then entering restart 9, the console says it is going to sleep, but it immeadiately wakes up and re-connects to the wifi and never seems to actually enter sleep mode.

Using Rile1 Wakeup with a timer still does not work either.

To quote myself as well :-)

Sorry... I thought that maybe the Rule1 Wakeup method needed a pin set not just for wakeup, but also for entering deepsleep in that particular mode. If that's not the case, it still doesn't explain why I cant get this S3 to enter deepsleep mode using the setup described in the docs. 🙁

I have a Timer set in the GUI to wakeup the ESP at 1 hour before Sunrise, and the Timer is enabled.

I have set Rule1 Wakeup and enabled one-shot with Rule1 5. But the DeepSleep countdown does not begin.
You can see from the console log that no setting for Rule1 causes the DeepSleep countdown to begin as expected.
What am I doing wrong... or is this a bug?

Has anyone else been able to test this? I still haven't had any success making it work on this dev-board with the webcam build I'm running.

Since I haven't received any answers to this problem in a week, should I assume for now that this feature just isn't working yet due to this being a development build?
Tasmota 15.2.0.3 (d48c7d3-lvgl-haspmota)
I have an extra one of the camera boards mentioned earlier in the post that I can test with if anyone wants to point me to code updates to try :-)
My cameras are running off solar panels and batteries, so I would really like to get the deepsleep working with a sunrise wakeup and sunset deepsleep to save battery power through these long winter nights. Thanks.

I also have this function not working…

Does not work on ESP8266, works on ESP32-C3

Does not work on ESP8266, works on ESP32-C3

When you say "does not work" can you be more specific.
Is it not even going into deepsleep mode?
Does it go into deepsleep mode, but not wakeup?
Are you using the DeepSleepTime X cycling, or are you using the Rule1 Wakeup with a Timer set to "rule" as the output?
All of this is very important to determine before you say "it's not working"... especially if you are jumping in on someone else's thread with a "me too".

Also, I am using a custom build from the Development Release, NOT a pre-built release binary.... this is also a BIG difference.

I have confirmed that the DeepSleepTime cycling as well as the DeepSleep on Rule1 Wakeup using a Timer BOTH WORK ON ESP32 AND ESP32-S3 RELEASE BINARIES.

On the Custom Compile, the DeepSleepTime x cycling IS WORKING. The DeepSleep on Rule1 Wakeup using a Timer IS NOT WORKING.

Check the documentation, the 8266 may need some physical configuration, like a jumper from GPIO 16 to the RST pin in order for DeepSleep to work.
