Grant and revoke temporary gate access on RTU5024 and Callny G202 GSM gate opener modules. This guide covers 4 methods: manual add/remove via SMS, auto-expiring time-limited access, count-limited passes for deliveries, and weekly schedules. Includes specific tips for Airbnb hosts, property managers, and offices with contractor access.

A delivery driver is at your gate and you're not home. A guest is arriving at your vacation rental. A contractor needs access for three days. With a GSM gate opener, you can grant and revoke access remotely. Airbnb alone reported $91.3 billion in gross booking value for 2025 in its [Q4 2025 shareholder letter](https://s26.q4cdn.com/656283129/files/doc_financials/2025/q4/Airbnb_Q4-2025-Shareholder-Letter-Final.pdf), and that booking volume drives demand for remote access solutions that don't require on-site key handoffs. But the process depends on which module you have.

## How Temporary Access Works

A GSM gate opener maintains a list of authorized phone numbers. "Temporary access" means adding a number and removing it when access should end. According to the [ETSI GSM standard](https://www.etsi.org/technologies/mobile/2g), caller identification (CLI) is a core network feature that gate opener modules rely on for phone-number-based authorization. The key difference between modules is whether removal is manual (you do it) or automatic (the module does it after a set time or use count).

## RTU5024: Add, Remove, or Schedule

According to [RTU5024 manufacturer documentation](http://www.rtu5024.com/download/RTU5024-V2019.pdf), each module supports up to 200 authorized phone numbers (slots 001-200), providing ample capacity for property managers with rotating tenants. The [RTU5024](https://gate-opener.app/hardware/rtu5024/) lets you add a number permanently, or on firmware v1.7+ use time-limited access with automatic expiration -- a feature unique to the RTU5024 that Callny modules lack.

Grant permanent access (slot 150):

`1234A150#+447555123456#`

Syntax: `{password}A{slot}#{phone}#`

Grant time-limited access (slot 150, Apr 10-12 2026):

`1234A150#+447555123456#2604100800#2604121800#`

Syntax: `{password}A{slot}#{phone}#{startYYMMDDHHmm}#{endYYMMDDHHmm}#` — requires `{password}T{YYMMDDHHmm}#` clock sync first.

Revoke access (delete slot 150):

`1234A150##`

Syntax: `{password}A{slot}##`

**Best practice:** reserve slots 001-010 for family, 100+ for temporary guests.

## Callny G202: Manual with User Roles

The [Callny G202](https://gate-opener.app/hardware/callny-g202/) works like the RTU5024 (manual add/remove). The G203 variant adds a "Normal" user role that can only call to open, not manage settings. Safer for temporary guests.

## Best Method for Each Scenario

| Scenario | Best Module | Why |
| --- | --- | --- |
| Airbnb / vacation rental | RTU5024 (v1.7+) | Time-limited access auto-expires at checkout |
| One-time delivery | RTU5024 or Callny | Add, let them in, remove |
| Contractor (3 days) | RTU5024 (v1.7+) | Time-limited access for exact date range |
| Employee (business hours) | Callny G203 | Normal user role, limited permissions |
| Family visiting | RTU5024 or Callny | Manual add, remove when done |

## Tips for Managing Temporary Access

### Enable relay notifications

On RTU5024, send `1234GON11#GateOpen#` so you get an SMS each time the gate opens. On Callny, send `1234#R#` to enable relay notifications.

### Use dedicated slot ranges

Slots 001-010 for permanent users, 100+ for temporary. Makes cleanup easy.

### Never use Allow All mode

AA mode opens for any caller. Always use AU (authorized only) and manage the list.

### Revoke immediately

Callny has no auto-expiration, so set a reminder to remove numbers. RTU5024 v1.7+ supports time-limited users that expire automatically.

## Frequently Asked Questions

### Can I give access without knowing the guest's phone number?

No. GSM gate openers authorize by caller ID. You need the phone number.

### What if a guest tries after I've revoked access?

The module silently ignores unauthorized calls. The call disconnects without the gate opening.

### Can I see who opened the gate?

Yes. Enable relay notifications. The module texts slot 001 with the triggering number each time.

### How many temporary users at once?

RTU5024: 200 total (slots 001-200). Callny: 999 total.
