Connect an AXIS door lock relay

Connect an AXIS I/O relay module to Offision so meeting room booking panels can release electric strikes and manage door access automatically.

Updated 4 Sept 2026

An AXIS network I/O relay module connects an electric door strike to Offision. This enables room booking panels outside the door to unlock the room for authorized meeting attendees and automatically relock it when the unlock duration elapses.

Architecture diagram showing an AXIS A9210 module connected to a door strike and dialing out over MQTT port 8883 to Offision Cloud. The room panel outside connects over HTTPS port 443. No inbound firewall rules or VPNs are needed.

Communication is entirely outbound. The controller establishes an outbound MQTT session to Offision Cloud and receives unlock commands over that connection.

Prerequisites

  • An AXIS network I/O relay module (such as the A9210) powered and reachable on your LAN.
  • The door’s electric strike wired to the module’s RELAY output terminal.
  • The web address and admin password for the AXIS device.
  • A room booking panel already paired and assigned to the room.
  • Approximately 30 minutes.

1. Register the door lock in Offision

In the management console, navigate to Marketplace › Apps and select the AXIS tile.

Offision does not require the hardware’s local IP address or password. Offision generates unique connection tokens for the device to connect outward.

2. Review the configuration guideline

Open the newly created door lock device and select Config guideline from the left navigation rail.

The guideline provides your device’s unique connection credentials:

  • Client ID
  • Username
  • Password (time-limited access token)

If prompted with an Enable MQTT button, click it to activate the MQTT profile.

Keep this tab open while you configure the AXIS web interface.

3. Configure MQTT and rules on the AXIS device

Sign in to your AXIS device’s web interface and complete the three configuration steps:

  1. MQTT Client: Enter the broker address, Client ID, Username, and Password from the guideline.
  2. MQTT Subscription: Subscribe to the designated command topic using the exact filter specified.
  3. Event Rules: Create four event rules linking the relay output and status feedback to MQTT topics.

For exact step-by-step settings and parameter tables, see AXIS door lock settings reference.

4. Bind the door lock to the room panel

  1. Go to Devices › Booking panel › Devices and click on the room’s panel row.
  2. In the device edit dialog, select Door locks in the left rail.
  3. Check the box for the door lock and save.

Next, go to Devices › Booking panel › Panel configurations, open the configuration assigned to that panel, and enable Show open door button. Set your desired Open duration (seconds before the strike re-locks).

If you want administrators and meeting hosts to open the door outside scheduled meeting hours, also enable Booking operators open door any time under Check-in method.

5. Test physical and telemetry operation

Verify both directions:

  • Physical unlock: Tap Open door on the booking panel. The electric strike should click open and remain unlocked for the duration set in your configuration.
  • State feedback: While unlocking, observe the lock tile in the management console. It should switch to unlocked and return to locked automatically.

Troubleshooting

IssueResolution
Device status is Connected but relay never triggersVerify subscription topic filter ends with /#, and ensure Use default topic prefix is disabled.
Relay clicks but door remains lockedVerify wiring polarity on the RELAY terminal. Confirm event rule specifies RELAY rather than digital output O1.
Door remains permanently unlockedEnsure event rule Duration is set to 00:00:00 so the device does not lock the relay state internally.
Panel has no Open door buttonEnable Show open door button in the assigned panel configuration. For unscheduled hours, enable Booking operators open door any time.
