Let say I put 3 cameras in a trigger or a rule
If one detect motion, is there a way to know which one?
(Something similar to "$currentEventDevice" in WebCore)
Like if camera 1 detect motion, do something, if camera 2 detect motion do something else...
Or should I create 3 separate triggers/rules?
Create 3 separate rules if you want each to do something different than the other. If you want all to do the same result then one rule for all works, you can see the logs to identify the camera of 3 that did the trigger or use notification to get the device name using %device% on the notification
