i did not use the jlx12864 on esp32 but the screen on the ttgo-t-display module with special drivers in micropython

Yes. I need to write down a tutorial about this... i know i said i would but my boat complete refit takes two much time as it is a hull to complete boat refit. I apologize about the delay. I will do it eventually one day though.
If you dont have the board sean mentioned or if you want a bigger screen than the ttgo can offer i modified the ugfx driver and made the remote to work with a bigger screen with an aliexpress ili driver display. Look at my github page for the changes.

Thanks for your reply. A tutorial would be highly appreciated.
I have ordered the ttgo module on Amazon and will give it a try in the next few days. Do you have any experience whether the display is still readable in direct sunlight?

Ok, I have now got it running with Sean's micropython firmware file on a ttgo module.
I've been playing around with the sleep modes a bit. The 700uA mode works well. However, the poweroff mode seems to be controlled externally.
@seandepagniers: Can you explain what is controlled by pin 26 (power_down_pin_number)? Is it meant to control a mosfet?

are you using the latest master for the scripts on the esp32?
the schematic allows the ttgo to get into an even lower power state (0.1uA) to conserve battery but it will only wake when the auto button is pressed.

This is my (not yet tested) solution with a separate 'on' key. You can power off the device by pressing the menu and select buttons simultaneously.
I'm currently working on a waterproof remote with wireless charging dock. I will publish the whole thing when it is finished.
