User mod request: battery monitoring/deep sleep when LEDs are off for Adafruit ESP32 Feather v2

Is your feature request related to a problem? Please describe.
I am running a mobile instance of WLED on a hat and wanted to be able to monitor the battery percentage from the onboard lipo charger. I would also like my ESP32 device to enter deep sleep when the push button toggles the lights off to preserve battery power.

Describe the solution you’d like
I want a menu to be able to select a battery monitor, according to Overview | Adafruit ESP32 Feather V2 | Adafruit Learning System you should be able to use this data from “pin (GPI35) - This ADC pin can be used to read the data from the battery monitor. Basically, perform an analog read and multiply by two, to get a rough sense of the lipoly battery voltage.” I would also like a checkbox in the UI to enable/disable deep sleep when Leds are powered off. I am currently using an Adafruit ESP32 feather v2 and a 3.7v 30,000mah lipo jst battery.

I am really interested with bulk mobile LED projects and I have ordered enough hw for around 10 setups including esps , rgb shields and charging modules. The battery power monitoring is really very important in such projects but I only thought to add an extra board like the below , might add a little size and more power consumption , not sure if that will do

I never thought that a fork is possible without extra HW for monitoring the battery in any case or is that not correct and you can do it without extra HW ? or is the esp32 you listed is having battery monitoring on its own



The adafruit feather v2 has a built in lipo charger and battery monitor.

Yes , The picture I attached is from your MCU specs sheet , In all cases you may wait for a fork ( which I do not see possible without you doing the work ) or try with an extra monitoring board . Good luck
