Questions about this item

The 3.5 in width suits narrow stile and storefront doors, and the lock is designed for out-opening configurations.

What wireless standard does the app use and what range does it cover?

The app connects via Bluetooth, so control works within Bluetooth range; Wi-Fi control requires a separately purchased gateway.

What physical preparation is needed to mount this knob on my door?

The unit measures 9 in x 3.5 in x 3.5 in and fits out-opening, narrow stile doors; charge the lock for at least 3 hours before installation.
