I've been trying to integrate my own application with WittyPi4 and tested out the scheduled shutdown/startup for the first time today. The shutdown executed correctly and when I expected but the programmed start-up didn't happen when I had expected. And now my WittyPi4 is now in a non-recoverable state! Here's what I see:
- The WittyPi4 heartbeat LED is working fine as you would normally see
- Pressing the power button results in power coming on very briefly to the RPi5 board and then immediately off again
- Removing the WittyPi4 power source and powering the Rpi5 directly from USB 5V, the pi boots up just fine. However, the I2C reads mostly fail when accessing the WittyPi4 i.e., it looks like the temperate sensor is reading back fine but everything else appears to be failing I2C reads
Any ideas what is going on or how to troubleshoot further?

Just to add another piece of information. If I rapidly keep pressing the power button on WittyPi4 it seems that that the power does not cut. If I do this for long enough, the RPi5 will boot successfully and the unit remains powered. However, I am still seeing I2C read failures.
