[Solved / Archived] WittyPi 4 mini doesn't start up and/or doesn't wake up and red led just blinking shortly

Most probably is the same issue discussed here: https://www.uugear.com/forums/technial-support-discussion/witty-pi-4-tapping-the-on-off-switch-doesnt-turn-on-the-raspberry-pi/

Hi,

Thanks for your quick answer and will try what you suggested in the other post.

@admin Thanks! It worked! Strange thing is that I use an official 3A RaspberryPi poweradapter (and tried several ones). Alah, the capacitor worked!

Only thing that keeps on happening is:

[2023-11-10 11:20:01] [Warning] System and RTC time seems not synchronized, difference is 24s. System time is "2023-11-10 11:20:01 CET", while RTC time is "2023-11-10 11:20:25 CET". Please synchronize the time first.
[2023-11-10 11:20:01] Schedule next shutdown at: 2023-11-10 11:35:00
[2023-11-10 11:20:02] [Warning] System and RTC time seems not synchronized, difference is 24s. System time is "2023-11-10 11:20:02 CET", while RTC time is "2023-11-10 11:20:26 CET". Please synchronize the time first.

I solved it though this script in beforeScript.sh, some sort of old syncTime.sh. Got it out of wittyPi.sh. Don't know if I need everything

[ -z $BASH ] && { exec bash "$0" "$@" || exit; }
#!/bin/bash
# file: wittyPi.sh
#
# Run this application synchronise time
#

# include utilities scripts in same directory
my_dir="`dirname \"$0\"`"
my_dir="`( cd \"$my_dir\" && pwd )`"
if [ -z "$my_dir" ] ; then
  exit 1
fi
. $my_dir/utilities.sh
. $my_dir/gpio-util.sh

if [ $(is_mc_connected) -ne 1 ]; then
  echo ''
  log 'Seems Witty Pi board is not connected? Quitting...'
  echo ''
  exit
fi


if [ $(is_mc_connected) -eq 1 ]; then
  firmwareID=$(i2c_read 0x01 $I2C_MC_ADDRESS $I2C_ID)
  firmwareRev=$(i2c_read 0x01 $I2C_MC_ADDRESS $I2C_FW_REVISION)
fi

# sleep 20

# interactive actions
# synchronize_with_network_time()
if $(has_internet) ; then
  log '  Internet detected, apply network time to system and Witty Pi...'
  net_to_system
  system_to_rtc
else
  log '  Internet not accessible, skip time synchronization.'
fi

Thanks!

Bart.
