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

No. GSM gate openers authorize by caller ID, so you need the guest's phone number.

What happens if a guest tries to open the gate after access is revoked?

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

How many temporary users can I have at once?

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

Temporären Torzugang für Gäste und Lieferanten einrichten

Q: Can I see a log of who opened the gate?

Yes. Enable relay action SMS notifications. The module texts slot 001 with the triggering phone number each time the gate opens.

Eigentümer gewährt Gast temporären Torzugang per Smartphone

Temporären Zugang einrichten auf RTU5024 und Callny. Manuell, automatisch ablaufend, gezählt, Wochenplan.

Überspring die SMS-Befehle. Probier GateOpener.

Ein Lieferfahrer steht am Tor und du bist nicht zu Hause. Ein Gast kommt in deiner Ferienwohnung an. Ein Handwerker braucht drei Tage Zugang. Mit einem GSM-Toröffner kannst du Zugang aus der Ferne gewähren und widerrufen.

Wie funktioniert temporärer Zugang?

A GSM gate opener maintains a list of authorized phone numbers. "Temporary access" means adding a number and removing it when access should end. 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: Hinzufügen, entfernen oder planen

The RTU5024 supports up to 200 authorized numbers (slots 001-200). 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: manuell mit Benutzerrollen

Works like 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.

Tipps für temporären Zugang

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.
