Smart Lock WiFi Gateways

Jump to the product listings ↓

A gateway bridges a Bluetooth lock to your network so it can be reached remotely. Modules do the same job from inside the lock, on Zigbee, Z-Wave or WiFi. Neither changes how the lock works at the door; both change what you can do when you are not standing at it.

Gateway or module?

Type Where it sits Consideration
Plug-in gateway or bridge A mains outlet within radio range of the lock No modification to the lock. Placement between router and lock is what determines reliability
Internal network module Inside the lock body, in a dedicated slot Neater, no separate device to power. Adds to the lock's battery draw
Zigbee or Z-Wave module Inside the lock, joining a home automation mesh Requires a compatible hub. Mesh networks extend range through other powered devices. Zigbee, Z-Wave and door modules

Placement and setup

  • 2.4 GHz only — gateways almost universally use the 2.4 GHz band and cannot join a 5 GHz network.
  • Split your SSIDs — band steering under a single network name is the most common cause of dropouts. The band-steering problem.
  • Midway placement — the gateway needs signal from the router and from the lock. The midpoint usually beats putting it next to either.
  • Avoid metal and masonry — a gateway on the far side of a rendered wall from the lock will be unreliable.
  • Keep it powered — a gateway on a switched outlet or a power board that gets turned off will silently stop working.
The gateway comparison guide sets out the differences between generations, including which support dual-band networks and which have the better range.

Common questions

Do I need a gateway?
Only if you want to control or monitor the lock when you are not near it. Everything at the door works without one. What a gateway does.
Will any gateway work with any lock?
No. Gateways are platform specific. A gateway for one platform will not connect a lock from another, even where the hardware looks similar. Cross-brand interchangeability.
Where should I put the gateway?
Roughly midway between the router and the lock, in a permanently powered outlet, with as little masonry in the path as possible. Gateway placement.
