Domoticz voorbeeld II (puur python)

[forumadmin]

Hieronder een 2e voorbeeld van een Python script voor Domoticz. 
Als extra zal er nog een cron job moeten worden aangemaakt.
Met als regel:

*/5  * * * * python /home/pi/domoticz/scripts/beeclear.py

Sneller laten updaten naar domoticz heeft voor de logging geen zin, omdat dit niet wordt opgeslagen door Domoticz.
