How it works
A smart controller connects to the gate board and to the internet through Wi-Fi or a SIM, or to your phone directly through Bluetooth. An app sends the open or close command.
Smartwatch
Some apps show buttons on a paired smartwatch so you can open a gate from your wrist. Support depends on the controller and the app.
Questions to ask
Which apps and phones are supported, how internet outages are handled, how guest access works and whether a physical remote still works as backup.
