So a couple of things, 1 when I connect my 5v 5amp power supply to the usb c, my RPi 5 is saying that the power supply is too low.
So I connected a 12v supply to the XH2.54 connector and that seems to work....but

After the successful install of the software, I can not get the wittyPi.sh to open.  I keep seeing : Seems Witty Pi board is not connected? Quitting...

What am I doing wrong?

Please post separated topics for different questions, as required by our forum rules. Putting multiple questions in one topic may save you one minute or two, but that makes some questions and their answers more difficult to be searched and found.

Witty Pi 4 uses AO4616 as MOSFET switch to control the power connection, which has about 0.04 Ohms resistor when it is on. Depends on the actual current that goes through it, a voltage drop will happen. Although Raspberry Pi advertised to accepts DC 5V +-5% (which means 4.75V~5.25V), in reality it starts to complain about the voltage, which is much higher than 4.75V. It is possible that the actual voltage that applied to Raspberry Pi was not high enough and that triggered the warning. However it should not become a real problem as long as that warning sign dispeared later.

The "Seems Witty Pi board is not connected? Quitting..." message will be printed when Witty Pi's software can not detect Witty Pi's hardware via I2C bus. Witty Pi 4 emulates an I2C device with address 0x08 on Raspberry Pi's I2C bus '1'. If you check its source code, you will see it actually calls "i2cdetect -y 1" to detect Witty Pi.

Please check your connection first, poor connection may cause failed I2C communication, as well as low-voltage warning on boot.

As I remember, Witty Pi's software version 4.21 has not been released yet, and you cannot install it with the command suggested by the user manual. How do you get this version of software? If you install the software manually, it is also possible that something has not been taken care and that causes failed I2C communication.

ok so I figured out that I had my program using the same GPIO as the witty.  I changed that and I was able to get to the witty setting screen.
