# Reolink and KNX: map commands and feedback to group addresses

Context: Link’nX web: KNX gateway table of a declared Reolink camera

The Reolink gateway table in Link’nX maps the group addresses of your KNX project to the commands of a Reolink camera (floodlight, brightness, siren, infrared, PTZ position, reboot) and to its status feedback (floodlight, infrared, motion, person, vehicle or pet detection). A KNX object can then control the camera without going through a scenario.

Intended for the authorized installer or administrator. For a scenario action or a detection trigger, follow the [Reolink commands and detections guide](https://wiki.can-nx.com/en/guides/link-reolink-automation/) instead.

## Before you start

- The camera has gone through the [Reolink declaration](https://wiki.can-nx.com/en/guides/link-camera-devices/): check in particular the channel and the model’s functions.
- The group addresses and their DPTs are defined in the KNX project. Check them with the installer.

## Open the camera’s gateway table

In **Devices → Security & Access → Reolink**, click the **Gateway mode configuration two opposite arrows**, to the left of the camera’s pencil.

The [KNX table guide](https://wiki.can-nx.com/en/guides/link-gateway-table/) describes the address formats, the filters and the **Active** checkbox in the header, which also acts on hidden rows.

## Map the KNX commands

1. In the **Actions** tab, choose the useful rows using the table below.
2. For each intended row, fill in **Address** with the KNX group address assigned to this function and check **Active**.
3. Click the **floppy disk at the bottom right** before switching tabs. Wait for **Succès** (Success) with **Données sauvegardées avec succès !** (Data saved successfully!).

| **Actions** tab | DPT | Meaning of the value |
| --- | --- | --- |
| **Floodlight** | **1.001** | 1 requests switching on, 0 switching off. |
| **Floodlight brightness** | **5.001** | Percentage from 0 to 100. To request an explicit switch-off, also use the appropriate **Floodlight** command. |
| **Siren** | **1.001** | 1 activates, 0 deactivates. |
| **Infrared lights** | **1.001** | 1 allows the infrared to operate automatically, 0 disables it. |
| **PTZ preset** | **5.010** | Integer number of the preconfigured position, from 1. Zero does not designate a position to use. |
| **Reboot** | **1.001** | 1 requests the reboot; 0 does not trigger it. |

## Map the status feedback

1. Open the **second tab**, with a speech-bubble icon.
2. Map the desired rows to their group addresses and check **Active**.
3. Save this tab in the same way.

Commands and feedback are separate associations.

| Feedback | DPT | Reading |
| --- | --- | --- |
| **Floodlight state** | **1.001** | Activation state of the floodlight. |
| **Floodlight brightness state** | **5.001** | Percentage reported by the camera. |
| **Infrared lights state** | **1.001** | Infrared allowed or disabled; this state does not tell whether the lamps are lighting at that moment. |
| **Motion**, **Person detected**, **Vehicle detected**, **Pet detected** | **1.001** | State of the corresponding detection, if available on the model. |

## Check the result

1. Go back to the list, reopen the gateway and review the saved values.
2. Send a command from the bus, for example with the ETS group monitor, and watch the camera: **Données sauvegardées avec succès !** only validates the save.
3. Check each feedback on its own group address.

## Troubleshooting

- Check the right camera and its channel, the address, the **Active** checkbox, the DPT and the function actually available.
- Treat missing feedback as missing information, not as a zero value, a stop or an absence of detection.
- The rows are the same for all models: check that the camera has the floodlight, the PTZ motor or the detection concerned.
- For a saved command without effect or a missing detection, follow the [Reolink troubleshooting](https://wiki.can-nx.com/en/guides/link-reolink-automation/).

If the checks have already failed or if an association remains uncertain, contact support@can-nx.com with the context, the row concerned and the tests done.
