Found a real fix for this on youtube. Solution requires writing PSU_MAX_CURRENT=5000 to the Pis eeprom. See https://www.youtube.com/watch?v=lEZccWuOXuo. About 6:50 in.

Before doing this it might be wise to check your applied voltage by "vcgencmd pmic_read_adc EXT5V-V"

Neither of these are my idea ...

Having a CarPiHat might help better integration with Hudiy. Just an idea.

Did anyone get the Hudiy provided final code to work (on page 2). My first several attempts failed but that may just be me and my lack of software savvy and thumb fingers. I will try from scratch again today. TIA.

Wow that sounds nice. Maybe he could place the code on GitHub?

Another user here. I will try the software as soon I finish the hardware redo. Thanx Again.

I need to stop doing hardware mods. I am replacing the relay powering the internal hub with one with a variable time delay to allow a bit (1-2 seconds) of startup before the hub is powered. Also cleaned up the assembly a bit while changing to a cm2606 device.

The real time clock and shutdown scripts at https://github.com/SamT-J/CarPiHat/wiki/Quick-Start-Guide under "Real Time Clock" and "Safe Shutdown Example:". Both need the depreciated RC.local The shutdown script also failed me right of when I tried to "pip install rpi-lgpio" and then the need for RC ...

It would be nice if the designers/original programmers of/for the CarPiHat resolved this problem for everyone. My planned work around is delayed while I do some hardware tweaks.

As I said noob in action! Thanx! I will look forward to GPIO control for various actions!
