Интеграция PMS отеля с KNX: автоматизация заезда/выезда через шлюзы Fidelio и Opera

Вебхук заезда Opera → поток KNX

1. Guest checks in at reception → Opera processes check-in
2. Opera fires POST to middleware webhook:
   {
     "event": "reservation.check_in",
     "room_number": "101",
     "guest_name": "Schmidt, Klaus",
     "arrival": "2026-06-05T14:00:00Z"
   }

3. Middleware receives event:
   a. Parse room_number → "101"
   b. Map to KNX GA block: main=10, sub=101
   c. Build KNX telegram sequence:

   → GA 10/101/5 DPT 18.001 = 0x01 (scene 1: Welcome)
     — Lights 70%, blinds 50%, HVAC comfort
   → GA 10/101/4 DPT 9.001 = 21.0 (comfort setpoint)
   → GA 10/101/0 DPT 1.002 = 1 (presence flag: room assigned)

4. KNX IP gateway (KNXnet/IP):
   Receives tunnelling request from middleware
   Forwards telegram onto KNX TP bus → room 101

5. MDT SCN-RT55 in room 101:
   Receives scene 1 telegram → executes welcome scene
   Receives setpoint telegram → switches HVAC to comfort

Opera check-out event → middleware → KNX:

  GA 10/101/5 DPT 18.001 = 0x02  (scene 2: Eco — lights off)
  GA 10/101/4 DPT 9.001  = 18.0  (economy setpoint — winter)
  GA 10/101/1 DPT 1.001  = 0     (DND cleared)
  GA 10/101/2 DPT 1.001  = 0     (MUR cleared)
  GA 10/101/0 DPT 1.002  = 0     (presence flag: room vacant)

  Blind control:
  Blind GA send position 50% (UV protection, neutral)

  TV:
  KNX switch actuator GA → TV standby OFF telegram

  Housekeeping notification:
  Middleware → housekeeping system API: room 101 vacated
  Housekeeping app shows room 101 as "Ready for cleaning"
  (alternatively: KNX GA to housekeeping BMS panel)

Guest requests 07:30 wake-up via Opera guest portal

Opera scheduled task: 07:30:00 → wake-up event for room 101

Middleware receives event at 07:29:50 (10s pre-run buffer):
  t+0:00 → GA 10/101/6 DPT 1.001 = 1 (wake-up trigger)
           Room display shows: "Good morning — 07:30"
           HVAC switches to comfort setpoint (21°C)
  t+0:30 → Lighting scene: 10% warm white (gentle start)
  t+1:30 → Lighting scene: 30% warm white
  t+3:00 → Lighting scene: 60% cool white (fully awake)
  t+5:00 → Blind position: 30% (gentle morning light)

Phone call (optional):
  Parallel to KNX: middleware triggers PBX phone call to room
  (Opera can do this natively — keep as backup)

Wake-up confirmation to PMS:
  GA 10/101/6 DPT 1.001 = 0 after 10 minutes
  (or: guest acknowledges on room display → GA → middleware → Opera)

Вебхук Mews → Home Assistant → KNX

1. Mews Operations → Settings → Webhooks
   → Add webhook: https://your-ha-instance.domain.com/api/webhook/mews_checkin
   → Events: reservation.check_in, reservation.check_out

2. Home Assistant configuration.yaml:
   homeassistant:
     packages: !include_dir_named packages/

3. packages/hotel_automation.yaml:
   automation:
     - alias: "Mews Check-In to KNX"
       trigger:
         platform: webhook
         webhook_id: mews_checkin
       action:
         - variables:
             room: "{{ trigger.json.space_id | default('') }}"
         - service: knx.send
           data:
             address: "10/{{ room }}/5"
             payload: 1    # Welcome scene
             type: "scene"
         - service: knx.send
           data:
             address: "10/{{ room }}/4"
             payload: 21.0
             type: "temperature"

4. Public HTTPS endpoint:
   Cloudflare Tunnel → HA instance (no port forwarding)
   OR: Dedicated public IP with Let's Encrypt SSL

Настройка покомнатного учёта энергии

Hardware: Carlo Gavazzi EM110 single-phase MID meter
  — DIN rail, Modbus RTU RS485 output
  — Accuracy class 1 (MID approved for billing)
  — One meter per room at floor distribution board

Interface: Modbus/KNX gateway (e.g., Zennio KLIC-DD or
           ABB M2M-WEB-HQ Modbus gateway)
  — Poll EM110 register 40097 (kWh active energy) every 15 min
  — Write to KNX GA 10/room/10 DPT 14.058 (energy, kWh)

Middleware energy billing logic:
  — Read GA 10/room/10 daily at 00:00 (snapshot)
  — Calculate daily consumption: today − yesterday
  — If daily kWh > 5 kWh threshold:
    → Opera folio entry: "Energy supplement: X kWh × €0.30"
  — Monthly report: sum per room per stay

Note: EN 62056 DLMS/COSEM metering is NOT required at
room level — Modbus MID meter is sufficient for hotel
energy billing at the sub-metering level. DLMS/COSEM
is required for utility grid metering only.
