output=short - return only on/off
fan_with_switch.sh
#!/bin/bash
# Run read_switch.py and capture the output
switch_status=$(/home/pi/Pigrow/scripts/triggers/read_switch.py name=fantoggle)
# Check if switch_status equals "on"
if [ "$switch_status" == "on" ]; then
# If switch is on, run fan_on.py
/home/pi/Pigrow/scripts/cron/fan_on.py
else`
# If switch is off, log the message "over-ride switch enabled, not turning on fan"
/home/pi/Pigrow/scripts/triggers/write_log.sh script=fan message="over-ride switch enabled, not turning on fan"
