Inoltro eventi KNX da NVR e VMS: Milestone, Genetec e Synology Surveillance Station

Configurazione regola evento Milestone XProtect

XProtect Management Client → Rules and Events → Rules → New Rule

Rule name: CAM-01 Motion → KNX Alarm
Trigger: Event → Devices → Camera → Motion Started
  Camera: [CAM-01 Entrance]
  Schedule: Always (or restricted hours for arming logic)

Actions:
  Action type: Send HTTP notification
  URL: http://<ARISTO-BewO-IP>:8080/knx/write
  Method: POST
  Content-Type: application/json
  Body:
  {
    "groupAddress": "8/0/1",
    "value": 1,
    "dpt": "1.001"
  }

Second rule for Motion Stopped:
  Trigger: Motion Stopped → same camera
  Body: { "groupAddress": "8/0/1", "value": 0, "dpt": "1.001" }

Note: XProtect Express does not include HTTP notification actions
— requires at least XProtect Professional for HTTP action type

Scheletro middleware Python Genetec → KNX

# Genetec SDK events → KNX via knx-stack (xknx Python library)
# Requires: Genetec Security Center SDK licence + xknx

from xknx import XKNX
from xknx.core import XknxConnectionState
import Genetec.Sdk  # Genetec SDK .NET assembly via pythonnet

GA_MOTION_CAM01 = "8/0/1"

async def on_genetec_event(event):
    if event.EntityType == "Camera" and event.EventType == "MotionDetected":
        camera_name = event.Entity.Name
        if camera_name == "CAM-01 Entrance":
            async with XKNX() as xknx:
                await xknx.core.start()
                from xknx.remote_value import RemoteValueSwitch
                await xknx.telegrams.put(
                    Telegram(
                        destination_address=GroupAddress(GA_MOTION_CAM01),
                        payload=GroupValueWrite(DPTBinary(1))
                    )
                )

# Alternatively: Genetec → HTTP POST → ARISTO BewO
# Using Genetec Event-to-Action: HTTP action on motion event
# POST to BewO endpoint with JSON body (same as Milestone approach)
# Requires Genetec Config Tool → System → General Settings → Actions

Configurazione Synology → Home Assistant → KNX

Step 1: Synology Surveillance Station
  Notification > Push Service > Webhook
  URL: http://<HA-IP>:8123/api/webhook/synology_motion_cam01
  Method: POST
  Trigger: Motion Detected — Camera: CAM-01 Entrance

Step 2: Home Assistant automation (automations.yaml)
  trigger:
    - platform: webhook
      webhook_id: synology_motion_cam01
      local_only: true
  action:
    - service: knx.send
      data:
        address: "8/0/1"
        payload: 1
        type: "1byte_unsigned"

  # Clear alarm after 30 seconds:
    - delay: "00:00:30"
    - service: knx.send
      data:
        address: "8/0/1"
        payload: 0
        type: "1byte_unsigned"

Step 3: KNX integration (configuration.yaml)
  knx:
    tunneling:
      host: <KNX-IP-router-address>
      port: 3671
      local_ip: <HA-machine-IP>

Configurazione ARISTO BewO HTTP → KNX

BewO web interface → Interfaces → HTTP Listener

Endpoint definition:
  Path: /knx/write
  Method: POST
  Authentication: Basic auth (configure username/password)

JSON body mapping:
  { "groupAddress": "8/0/1", "value": 1, "dpt": "1.001" }
  → BewO parses groupAddress and value
  → Writes DPT 1.001 value 1 to GA 8/0/1 on KNX bus

Test with curl:
  curl -X POST http://<BewO-IP>:8080/knx/write     -H "Content-Type: application/json"     -u admin:password     -d '{"groupAddress":"8/0/1","value":1,"dpt":"1.001"}'

  Expected: HTTP 200 OK
  ETS6 Group Monitor: GA 8/0/1 telegram appears within 200ms

Reverse direction — KNX-driven recording trigger:
  BewO monitors GA 8/3/0 (Alarm Armed = 1)
  → BewO HTTP client POSTs to NVR API:
    Milestone: XProtect REST API /recording/start
    Synology: http://<NAS>/webapi/entry.cgi (surveillance API)
  → Camera starts continuous recording on alarm arm
