Hi,
since we installed an ip cam at the front door with motion detection I wanted to make it possible to control dynamically when the camera is active and when not. I wanted to make it depend on times and if anybody is home.
As I have a Synology NAS with Surveillance Station running on it I use this for motion detection.
I found a way with using pimatic and the web api of the diskstation to realize it.
Here in the forum you can find solutions for checking if anybody is home (e.g. who is home).
So I made these rules to realize what I wanted (pimatic-shell-execute has to be installed):
{
"id": "cam-einschalten",
"name": "Cam einschalten",
"rule": "if $anybodyhome = 0 or [it is after 22:00 or it is before 07:00] then execute \"/root/scripts/cam_switcher.sh 1 on\"",
"active": true,
"logging": true
},
{
"id": "cam-ausschalten",
"name": "Cam ausschalten",
"rule": "if $anybodyhome = 1 and it is after 07:00 and it is before 22:00 then execute \"/root/scripts/cam_switcher.sh 1 off\"",
"active": true,
"logging": true
}
So now the camera is active at night or if nobody is home.
Here is the shell script:
#!/bin/bash

Maybe someone has use for this.
Update 2015-04-30
Changed the script an put in a possibility to send a value to a variable in pimatic.
With this there’s the chance to set a rule for fallback if the switch failed.
These are the rules for using this variable (you need to set up 2 variables in pimatic, one to set from the script and another one to compare with, in this case: $camStatusFeedback and $camStatusTarget.
{
"id": "cam-ausschalten",
"name": "Cam ausschalten",
"rule": "if $anke_oder_martin_zuhause = 1 and it is after 07:00 and it is before 22:00 then execute \"/root/scripts/cam_switcher.sh 1 off\" and after 30 seconds set $camStatusTarget = 0",
"active": true,
"logging": true
},
{
"id": "cam-einschalten",
"name": "Cam einschalten",
"rule": "if $anke_oder_martin_zuhause = 0 or [it is after 22:00 or it is before 07:00] then execute \"/root/scripts/cam_switcher.sh 1 on\" and after 30 seconds set $camStatusTarget = 1",
"active": true,
"logging": true
},
{
"id": "cam-ausschalten-fallback",
"name": "Cam ausschalten fallback",
"rule": "if $camStatusTarget changes and $camStatusFeedback = 1 and $camStatusTarget = 0 then $camStatusTarget = 1 and execute \"/root/scripts/cam_switcher.sh 1 off\" and after 30 seconds $camStatusTarget = 0",
"active": true,
"logging": true
},
{
"id": "cam-einschalten-fallback",
"name": "Cam einschalten fallback",
"rule": "if $camStatusTarget changes and $camStatusFeedback = 0 and $camStatusTarget = 1 then $camStatusTarget = 0 and execute \"/root/scripts/cam_switcher.sh 1 on\" and after 30 seconds set $camStatusTarget = 1",
"active": true,
"logging": true
}
