# If the gpioset commands indirectly issued by this service fail, such that the command:
#
#     systemctl status home-automation.service
#
# shows messages such as:
#
#     gpioset: error setting the GPIO line values: Permission denied
#
# then this service may be running before the system is ready. In that case, wait for the system
# to catch up. The wait (sleep) time depends on the particular Raspberry Pi board, and the OS.
#
# For example:
#   - no delay was necessary for a Raspberry Pi 1B+ board running Bullseye
#   - no delay was necessary for a Raspberry Pi 3B+ board running Bookworm
#   - a 15 second delay worked well with a Raspberry Pi 1B+ board running Bookworm
#
# Comment-out the following "TimeoutStartSec" and "ExecStartPre" lines if no delay is necessary.

TimeoutStartSec=infinity
ExecStartPre=/usr/bin/sleep 15

ExecStart=/home/pi/bin/hainit &
