I am fairly new to Smart Things and only now found out that I can install apps through the Web as well. I have a Smart Sense Multi on 2 of my doors and would like to get activity notifications also, not only open and closed.
I managed to install the app on 1 sensor using my home location. I configure it using the Web or on the phone and save it. Then it works. If I go back to My Smart Apps and do the same with my second Smart Multi, the app will always be removed from the first one. So far I have not managed to get activity notifications on both sensors.
