Aeotec Nanomote now shipping in the US (March 2019)

I was curious can this be used as a presence sensor? My in-laws moved in and believe it or not they do not have a smart phone so I am looking for something they can have on their key chain that will disarm the alarm when they get home and has a few buttons to control just a few simple routines (turn house lights on, arm the alarm at night and if needed disarm the alarm. The need for a few buttons is why I did not go with the SmartThings presence sensor.

I read through this FAQ FAQ: Full list of buttons and remotes confirmed to work with SmartThings and it seems like many of the devices are no longer available.

If this can not be used a presence sensor do you have any recommendations? I would rather not build a dashboard on a tablet for them because they are not techy at all so just something that I can put on their key chains and tell them to “hit this button to turn the lights on” or “hit this button if the alarm goes off on you” is what I am after.

Thanks!
