All, thanks
I propose now the plugin. I tested it and I had no problem with
- Capture.PNG (50 KiB) Viewed 1462 times
The plugin is usefull to retrieve data from url. depending of the result of the response (String to find for On update / String to find for Off update:), the plugin set a switch on or off in domoticz
I use it to retreive the state of the output of two cameras (DCS 2210 & DCS2230) :
I set up event in each cam to put the output to ON during 8 second when a movement is detected.
So the plugin is set up to retrieve the state of the cams each 4 seconds by retrieving the output state of cam with the following url
http://IPADRESS/config/io.cgi
Code: Select all
# PirCamChecker
#
# Author: TiXav, Sept 2017
#
# For My DLINK DCS2210 or DCS 2230
# I set the outpout of the camera On during 8 seconds when the cam detects someone
# So I set the Mode1 to 4 seconds to be sure the plugin catch all the detections
