HMS Questions

Hi, I had a few questions before I receive the HMS.

  1. I understand that the hub needs ethernet to set up but can you use wifi after the setup so you can move it to a central location?

  2. Can you change the volume of the alarm?

  3. In test mode does it set off the alarm or can you have it chirp and use it as an announcer rather then an alarm?

  4. If my wife has the app I know only one phone is called after a trigger but can she still arm and disarm from the app?

Thanks for any help!
