Everyone's Presence

“Everyone’s Presence” is a SmartApp that sets a simulated presence sensor to “present” or “not present” based on a group of presence sensors. If no sensors are home, it sets to “not present”. If at least one sensor is home, it sets to “present”. To use this, you need to create a “Simulated Presence Sensor” in the IDE. I created this SmartApp to be used with IFTTT. I know this could have been done with a virtual switch, but I thought it might come in handy later for something else. I’m sure somebody will see another use for this.

Thank you for the work and your help. I was looking to do something like this as well, in order to improve the way that ST works with Presence sensors. I wanted to incorporate a HA Lock, but did not want it firing randomly without verification of two devices arriving home at the same time.

Thanks, I’m hoping to use this to set my thermostat to ‘home’ and ‘away’ using IFTTT… Thanks!

Question, @baldeagle072, do you have this in Github?

NM, I found it: https://github.com/baldeagle072/SmartThingsOther/blob/master/smartapps/baldeagle072/everyones-presence.groovy

Likewise, this is awesome! It seems odd that IFTTT doesn’t allow Modes to be used as a trigger. If it did then this wouldn’t be necessary because you could just say “whenever my Hub is in Away Mode [which would be based on “everyone’s presence”], then…”. Anyways, this definitely bridges the gap. Thanks!

I like this (setting a single simulated presence) better than using something that is tied to specific modes or routines, like Nobody’s Home. Thanks!

Oops… I can accidentally change the simulated sensor. I better not put it in my SmartTiles.

My thanks to baldeagle072 for Everyone’s Presence. I’m using it to pass joint presence status to HomeKit via Homebridge. Easy to install and is working great!

Is there any possibility a version of this could be written so Everyone’s presence could trigger an event?

I’d like to have ST recognize that every member of the family is home, and once the last member arrives, turn off the outside lights (after a set interval).
