Can I use the iQ4 HUB -IQPH051 WITHOUT WIFI. I would be REQUIRED to get the ATT Cellular LTE and NO OTHER. I wold be replacing my brinks account and crappy iQ #?? panel with this iQ4 Hub. Compatibility with my current quolsis products – door sensoros and Motion Cams !! I will not intend on using WiFi and will use Cellualar only.
