You can also make the python script run as a service using a shell script. First create a shell script to run the python script like this (scriptname arbitary name)
proxy2:/usr/local/bin# cat /usr/local/bin/getCyrusUsers.sh
#!/bin/sh
script='/usr/local/bin/getCyrusUsers.py'
/usr/bin/python $script &
now make a file in /etc/init.d/scriptname
proxy2:/usr/local/bin# cat /etc/init.d/getCyrusUsers
#! /bin/sh
APPNAME=getCyrusUsers
PATH=/bin:/usr/bin:/sbin:/usr/sbin
DAEMON=/usr/local/bin/getCyrusUsers.sh
PIDFILE=/var/run/$APPNAME.pid
test -x $DAEMON || exit 0
. /lib/lsb/init-functions
case "$1" in
start)
log_daemon_msg "Starting $APPNAME"
start_daemon -p $PIDFILE $DAEMON
log_end_msg $?
;;
stop)
log_daemon_msg "Stopping $APPNAME"
killproc -p $PIDFILE $DAEMON
PID=`ps x |grep feed | head -1 | awk '{print $1}'`
kill -9 $PID
log_end_msg $?
;;
force-reload|restart)
$0 stop
$0 start
;;
status)
status_of_proc -p $PIDFILE $DAEMON $APPNAME && exit 0 || exit $?
;;
*)
echo "Usage: /etc/init.d/$APPNAME {start|stop|restart|force-reload|status}"
exit 1
;;
esac
exit 0
Now you can start and stop your python script using the command /etc/init.d/scriptname start or stop.
You can also make the python script run as a service using a shell script. First create a shell script to run the python script like this (scriptname arbitary name)

DAEMON=/usr/local/bin/getCyrusUsers.sh
PIDFILE=/var/run/$APPNAME.pid
test -x $DAEMON || exit 0
. /lib/lsb/init-functions

echo "Usage: /etc/init.d/$APPNAME {start|stop|restart|force-reload|status}"
exit 1
;;

exit 0
Now you can start and stop your python script using the command /etc/init.d/scriptname start or stop.

OpenHAB - NodeRed
Nápadu Node-RED as a rule/script engine for openHAB
Někdo namítá že to bude líné:
Někdo namítá že to bude líné:
- Sensor—openHABRuleEngine—Actuator
- Sensor—openHAB—MQTT—NodeRED—MQTT—openHAB—Actuator
Námitka: Currently I observe maximum of 10ms delay in Node-RED processing. Z-wave has it much bigger.
Tímto způsobem je možné nepoužívat rules od OpenHABu
