What is everyone using to get emails when a window or a door is (left) open
Left open for an extended period?
Right now… nothing that I know of.
I am sure a small Luup program could be created that starts a timer whenever a sensor is open. If the sensor is not closed within a specified amount of time then it could trigger an event… however I do not think vera can do this without luup code.
You might want to ask over in the Luup/Development forum.
I recently set it up, using Twitter as notification engine.
One notification goes off when the door is open; besides that I have a scene that checks door status every 20 min and notifies me if it’s “still” open
