Gallagher
Command Centre Access Control with REST API and KNX Building Integration
Gallagher (Hamilton, New Zealand, with strong presence in UK, Netherlands, and Germany) provides access control and perimeter security — Command Centre is deployed in European airports, utilities, banks, and commercial campuses. REST API integration with KNX building automation enables door access events to trigger lighting, HVAC, and monitoring responses automatically.

How we use Gallagher
Gallagher Command Centre 8.x: web-based access control management. REST API v8 (CC REST API): OAuth2 client credentials flow — POST to '/api/access_control/rest/v1/oauth2/token' with client_id and client_secret (configured in CC server settings). Token expires 3600s, auto-refresh required. Key endpoints: GET '/api/access_control/rest/v1/events?after={timestamp}' returns door events (cardReadValid, doorForced, doorHeldOpen) with door name, cardholder name, timestamp. POST '/api/access_control/rest/v1/doors/{id}/access' commands door to open remotely (for KNX touchpanel door release button integration). Node-RED bridge: Gallagher Node-RED package (npm install node-red-contrib-gallagher). Node-RED polls Gallagher REST API every 2s for new events. On cardReadValid event at office door → inject KNX GA 'Lights Floor 2 On' (DPT 1.001) and HVAC occupied mode (DPT 1.019). KNX binary input → Node-RED → Gallagher REST API door open command. T15 multi-technology reader: reads 125 kHz Prox, HID iCLASS, MIFARE, and Bluetooth. OSDP v2 protocol for encrypted communication to Gallagher HBUS controller. Gallagher FT series fence detection: perimeter intrusion → Gallagher event → Node-RED → KNX alarm relay. Multi-tenant office: different departments have separate Gallagher card reader zones — each zone maps to dedicated KNX HVAC zone occupancy and lighting scene.
Gallagher Command Centre REST API bridges access events to KNX via Node-RED or custom middleware — door open events trigger lighting and HVAC, while KNX touchpanel buttons send door release commands back to Command Centre.
Used in these project types
Gallagher products
Key components we install
Command Centre 8.x software
Web-based access control management platform. REST API v8 with OAuth2 for KNX integration. Manages card readers, doors, cardholders, and access levels. Used in European airports, utilities, and commercial campuses. REST API webhooks (CC 8.10+) push events in real-time, eliminating polling.
T15 multi-technology reader
Multi-technology card reader supporting 125 kHz Prox, HID iCLASS, MIFARE Classic/DESFire, and Bluetooth. OSDP v2 encrypted communication to Gallagher HBUS controller. Used at main entrance and secure area readers where backward compatibility with legacy credentials is required.
T11 smart card reader
HID iCLASS and MIFARE smart card reader for secure access zones. OSDP v2 protocol. Suitable for internal secure areas requiring encrypted card communication. Integrates with Command Centre for KNX zone occupancy automation via REST API.
FT series fence intrusion detection
Fence-mounted vibration and disturbance detection for perimeter security. Perimeter intrusion events reported via Command Centre REST API. KNX integration via Node-RED: fence zone intrusion → KNX alarm relay output → security siren and CCTV camera PTZ preset trigger.
Gallagher FAQ
Does Gallagher have a native KNX interface?
No native KNX module exists — integration uses the Command Centre REST API with Node-RED, LOYTEC HTTP module, or custom middleware as the bridge. Node-RED with node-red-contrib-gallagher package is the most common approach for KNX integration in European installations.
What is the recommended polling interval for Command Centre events?
2-5 second polling via REST API is typical for real-time response. Gallagher webhooks (Command Centre 8.10+) push events in real-time, eliminating polling latency entirely. Webhooks are preferred for lighting and HVAC triggers where sub-second response is desired.
Can a KNX touchpanel open a Gallagher door remotely?
Yes — POST to '/api/access_control/rest/v1/doors/{id}/access' with a valid OAuth2 bearer token triggers a remote door open command. Map a KNX binary output (DPT 1.001) to trigger this REST call from Node-RED or LOYTEC HTTP module. The door ID is found in Command Centre web interface under door configuration.
