I created this for my needs, but decided I should share it as others may be interested in it.
With the new app I was not able to easily see who was present at my home, and who was away (with the classic app I was able to do this easily). With the new app, I was originally using a virtual switch with automations to track everyone’s mobile device, but I never did like how it appeared (I may be a little OCD…).
So, I created a new virtual presence sensor device handler:
Once installed in the groovy IDE, you can create a new device. To track a person’s mobile device, setup an automation to turn on or off the device with a mobile device being present or away. You should also be able to use it in webCore, but I have not tested it out.
