config.txt .
The power button can be used to wake up the OLED screen or to turn the Pironman off.
• Upon power-up, the OLED screen displays for 60 seconds before going into sleep mode. Using the power
button, you can wake up the OLED screen again later.
• You have 2 ways to get the Pironman to shut down.

There is also a way to safely turn off the Pironman by pressing and holding the power button for
2 seconds after configuring it.
