Introduce Yourself!

I’m just an old F___ (ST newbie) trying to keep up with the kids.
So far my sensors, light controls, and alarm seem to be working fine.
I have a Foscam F19821W camera on a Linear015Z outlet, so I can control the camera ON/OFF.
Camera records to my router NAS drive (SSD Samsung T1).
So far so good. My GE45631 keypad gives me device control at the entryway.
Currently my concerns are:

  1. Can I use the keypad to control MODES (to arm/disarm)?
  2. My wife does not have a smartphone…the keychain presence detectors seem to get bad reviews.
  3. How can my adult kids use the house when we are away?

Looking forward to expanding my knowledge & system.
