Airbnb Gate Access: How to Grant Guests Temporary Gate Codes Without Sharing Your Own

Option 1: GateOpener app with auto-expiring access (easiest)

In the GateOpener app, adding a guest is a tap-and-set-dates flow: pick their phone number, set a check-in date and a checkout date, save. The app sends the right SMS commands to your module to add them on check-in day and remove them automatically when they leave. You don't need to remember anything.

Works with both RTU5024 and Callny modules. €4.99 one-time, no subscription. The app is on Google Play.

Pros: fire-and-forget, no manual cleanup, works on any supported GSM module. Activity log shows exactly when each guest opened the gate.
Cons: Android only at the time of writing.

Option 2: Manual SMS commands per guest

The free option, if you don't mind doing it by hand for every booking. On check-in day, add the guest's number to your module's authorized list. On checkout day, remove it.

RTU5024 example — add a guest to slot 050 (reserve slot 050+ for guests, slots 001-049 for permanent users):

{pwd}A050#+{guest-phone}#

And on checkout day, remove them:

{pwd}D050#

Pros: free, works with any RTU5024 or Callny module.
Cons: easy to forget, no audit trail, prone to typos when typing international phone numbers by hand.

Option 3: Callny G202 PLUS time-window access

The Callny G202 PLUS firmware supports adding a user with a valid date range built into the command. The module enforces the window at the firmware level — no app required, no manual cleanup. Once the end date passes, calls from that number stop opening the gate even though the number is still technically in the user table.

Use this if you already have a Callny G202 PLUS and don't want to install an app. If you're choosing between modules specifically for Airbnb use, the G202 PLUS is the natural pick — but pair it with the GateOpener app for the activity log and cleaner per-guest UI.

Pros: hardware-enforced expiry, no app needed.
Cons: Callny SMS syntax is fiddly, no audit trail, requires a Callny-family module (won't work on an RTU5024).

Option 4: Smart lock + GSM gate combo

Some hosts pair a smart lock on the front door (Nuki, August, Yale) with a GSM-only gate. The guest gets a temporary code for the smart lock through Airbnb's keypad integration, and gate access via a separate mechanism — typically a permanent code shared on the welcome message.

Pros: integrated with Airbnb messaging for the door lock at least.
Cons: gate access still requires manual handling unless you also install a smart lock at the gate. Two separate systems to maintain.
