# Klereo KNX: connect Pool’nX to a Klereo Connect account

Context: Can’nX Cloud, Pool’nX window: Klereo type of pool, Authentification and Selected pool

Pool’nX reads the sensors and output states of a Klereo pool controller, and passes on to it the commands received from the KNX bus, through the pool’s Klereo Connect account. Choose the Klereo type, save the account credentials, then select the pool.

Intended for the installer or administrator who connects a Klereo pool to a KNX installation. For a PoolCop, follow [the PoolCop Cloud connection](https://wiki.can-nx.com/en/guides/pool-poolcop-connect/).

## Before you start

- The gateway’s **Pool'nX** window is open: see [open Pool’nX in Can’nX Cloud](https://wiki.can-nx.com/en/guides/pool-access/).
- You have the user name and password of a Klereo Connect account that can see the pool.
- Changing the type of pool erases the whole saved configuration: credentials, KNX addresses, options and temperature control. If the Pool’nX is already configured for another type, note its addresses first.

## Choose the Klereo type

1. In **Type of pool**, choose **Klereo**.
2. The **Confirmation** window shows **Do you really want to change the pool type?** and **All your saved data will be deleted**. Click **Confirm**.
3. Wait for the window to reload with the **Klereo** type.

**Cancel** restores the previous type without changing anything. If **Klereo** is already the displayed type, don’t choose it again: there is nothing to confirm.

## Enter the Klereo Connect credentials

1. Next to **Authentification**, click the button with the login icon. The **Modify the login details** window opens.
2. Enter the **User name** and the **Password** of the Klereo Connect account.
3. Click **Save**, available once both fields are filled in. **Success!** confirms the save and the window closes.

The saved password is never shown again: **The saved password is not displayed. Type it again to save changes.** To change the user name, you therefore also have to type the password again.

## Choose the pool

1. Back in the **Pool'nX** window, open the **Selected pool** list. It offers the pools of the Klereo Connect account, by name.
2. Choose the pool. The choice is saved immediately, with no other button.

The list stays empty until the credentials are saved. Pool’nX then reads the chosen pool, and again at the period set in [the options](https://wiki.can-nx.com/en/guides/pool-options/), 10 minutes by default.

## Check the result

1. Open **Pool Status** with its double-arrow button.
2. Check that **Live values** is followed by a green dot, that the **Value** column fills in and that **Last update:** shows a recent date.
3. Outputs and sensors renamed in Klereo appear under their Klereo name in the **Name** column.

Then map the KNX addresses: [statuses](https://wiki.can-nx.com/en/guides/pool-knx-status/), then the Klereo-specific values in [the Klereo status and command table](https://wiki.can-nx.com/en/guides/pool-klereo-knx/).

## Troubleshooting

| Symptom | Cause and action |
| --- | --- |
| **An error has occurred** when the window opens, **Selected pool** list empty | Klereo Connect returned no pool for these credentials. Enter the user name and password again in **Authentification**, then reopen the window. Check that this account sees the pool in Klereo Connect. |
| **Save** stays greyed out | One of the two fields is empty. The password must be typed again at every change. |
| **Live values** followed by **disabled** | No data has been received from the Pool’nX yet. Check that a pool is chosen and that the gateway is **Online** on its page, then reopen the table. |

If the problem persists, see [Pool’nX troubleshooting](https://wiki.can-nx.com/en/guides/pool-help/) or write to support@can-nx.com with the gateway name, the type of pool and the message displayed. Never send the Klereo Connect password.
