# DoorBird KNX integration with Link’nX: Cloud and local

Link’nX connects a DoorBird intercom to the KNX bus and to scenarios in two connection modes. **DoorBird (local)** talks to the intercom on the local network: relay opening, switching the light on, reacting to the doorbell and to motion. **DoorBird Cloud** goes through a DoorBird authorization; it lets you create or delete keypad codes from KNX and prepare access control bookings. This page sums up what each mode does and the commissioning order.

## Step-by-step commissioning

### Local DoorBird

1. [Declare the intercom](https://wiki.can-nx.com/en/guides/link-doorbird-local/) with its IP address and an **API user** that has the **watch always** permission, then find or enter its relays.
2. [Prepare the actions, triggers and KNX associations](https://wiki.can-nx.com/en/guides/link-doorbird-local-automation/).
3. [Add the actions and triggers to the scenario concerned](https://wiki.can-nx.com/en/guides/link-compose-scenario/), then check its activation and conditions.

### DoorBird Cloud

1. [Declare and connect the device](https://wiki.can-nx.com/en/guides/link-doorbird-cloud/) with the DoorBird administrator account, then check the **Connected** status and the **Keypad**.
2. [Associate the code commands with KNX group addresses](https://wiki.can-nx.com/en/guides/link-doorbird-cloud-gateway/) if codes are to be created from the bus.
3. For bookings, continue with [declaring an access control device](https://wiki.can-nx.com/en/guides/link-accesscontrol-device/).

## Good to know

- Local doorbell and motion events require the intercom to be on the same network broadcast domain as Link’nX, with firmware from November 2023 or later.
- In local mode, the KNX opening and light commands use DPT 1.017: 1 requests the action, 0 neither closes the door nor switches the light off. **Doorbell** and **Motion** (DPT 1.001) are pulses that return to 0 about two seconds later; **Reachable** (DPT 1.011) does not confirm that a relay opened.
- Without a declared relay, no opening row appears in the KNX table. Internal relays have the identifiers 1 or 2; a paired DoorController can use a compound identifier.
- With DoorBird Cloud, each code command receives a six-digit PIN in DPT 15.000. **Delete a code** only removes codes created by Link’nX, and the table provides no status feedback.
- A **Connection expired** status prevents creating or deleting codes until the device is reconnected with **Reconnect DoorBird**.
