# Set up the Boss’nX hypervision energy widget with Chart’nX

Context: Boss’nX: hypervision dashboard in edit mode, Link ChartnX dashboards window

The **Energy consumption** block of the Boss’nX hypervision compares the consumption of the supervisions linked to a Chart’nX dashboard. This procedure links each supervision to the Chart’nX dashboard of its project, then saves the hypervision dashboard.

Intended for the administrator or installer authorized to edit the hypervision dashboard.

## Before you start

- Each supervision to include is linked to the expected project.
- A suitable Chart’nX dashboard is available for this project.
- A wide screen makes this configuration easier.

## Open the Chart’nX configuration

1. Open the relevant hypervision, then **Hypervision dashboard**, as described in [the navigation guide](https://wiki.can-nx.com/en/guides/boss-hypervision-switch/).
2. In the header, click **Edit layout**. On a narrow screen, the button may show only the pencil; its accessibility label remains **Edit layout**.
3. Scroll the dashboard down to **Energy consumption** and click **Configure**. If the block shows **Set up the energy widget**, you can also use **Configure now**.
4. In **Link ChartnX dashboards**, wait for the dashboards to finish loading.

## Choose a dashboard for each supervision

1. Find the supervision name and the project shown in its row. Check that they match the building you want.
2. Open this supervision’s list and select its Chart’nX dashboard.
3. Repeat for the other supervisions to include.
4. Check that the choices are consistent: the combined consumption figures and units must allow the comparison you want.

As long as the window has not been confirmed, **Cancel** or **Close** discards the changes in progress there.

## Save in two steps

1. Click **Save** at the bottom of the window. The window closes and prepares the associations in the dashboard being edited.
2. Scroll back up to the header and click **Finish editing**: this is the step that saves the dashboard.
3. Wait for the save to finish.

To correct a choice after **Save**, reopen **Configure**, change it, then perform both confirmations again. Saving the dashboard is detailed in [the widget layout guide](https://wiki.can-nx.com/en/guides/boss-hypervision-layout/).

## Remove an association

1. Open **Edit layout → Configure**.
2. In the list for the relevant supervision, choose **— No dashboard selected —**.
3. Click **Save**, then **Finish editing**, and check the result.

Only the association used in the hypervision is removed: the Chart’nX dashboard itself is kept.

## Check the result

1. Check the supervisions shown in the chart.
2. To review the associations, go back to **Edit layout → Configure** and check each choice.
3. Close the window, then finish editing.

To use the charts afterwards, follow [reading consumption](https://wiki.can-nx.com/en/guides/boss-hypervision-energy/).

## Troubleshooting

| Display | Check and next step |
| --- | --- |
| **Configure** missing | First check that dashboard editing is active. As long as it is not, the block may show **Ask an administrator to enable this widget.**, including for an administrator. |
| Edit pencil missing, or unavailable after loading | Have the account’s rights checked. |
| **Project not linked** and **No cannX project is associated with this supervision.** | Have the administrator or installer check that this supervision is attached to the expected project: this window offers no field to create this attachment. |
| **No ChartnX dashboard is available for this project.** | Wait for loading to finish, then check the project shown and the existence of the expected dashboard with its administrator. |
| **Unable to load ChartnX dashboards.** or another loading error | Close the window, check your connection and reopen it once. |
| Saving fails | The choices may not have been kept: check each association again before trying again. See [energy troubleshooting](https://wiki.can-nx.com/en/guides/boss-hypervision-energy-help/). |

If the expected access remains unexplained, if the next step for an unlinked project is not established, if the list remains empty or if the loading error comes back, contact support@can-nx.com. Indicate the hypervision, the supervision, the expected project and dashboard, the message and the attempts made, without any password or access token.

French labels: **Modifier la disposition**, **Consommation énergétique**, **Configurer**, **Configurer maintenant**, **Associer les dashboards ChartnX**, **Enregistrer**, **Fin édition**, **Annuler**, **Fermer**, **— Aucun tableau sélectionné —**; project and dashboard names remain those of the installation.
