# Pool’nX: KNX gateway for Klereo and PoolCop pools

Pool’nX is the Can’nX KNX gateway for pools. It reads a Klereo controller, through Klereo Connect, or a PoolCop, through PoolCop Cloud, sends its measurements and states on the KNX bus and passes on to the pool the commands received from the bus: filtration, lighting, pump, valve, auxiliaries, setpoints. You configure it in Can’nX Cloud, from the gateway page.

## Getting started

1. [Open the Pool’nX window](https://wiki.can-nx.com/en/guides/pool-access/) from the gateway page in Can’nX Cloud and find its settings.
2. Connect the pool controller: [Klereo with the Klereo Connect credentials](https://wiki.can-nx.com/en/guides/pool-klereo-connect/) or [PoolCop with a PoolCop Cloud API key](https://wiki.can-nx.com/en/guides/pool-poolcop-connect/).

## Main tasks

**Connect the pool to the KNX bus**

- [Send statuses on the KNX bus](https://wiki.can-nx.com/en/guides/pool-knx-status/): water temperature, pH, ORP, pump, auxiliaries, alerts, each on a group address with its DPT.
- [Control the pool from KNX](https://wiki.can-nx.com/en/guides/pool-knx-commands/): each telegram received on a command address is passed on to the controller.
- Values and DPTs specific to each controller: [Klereo table](https://wiki.can-nx.com/en/guides/pool-klereo-knx/) and [PoolCop table](https://wiki.can-nx.com/en/guides/pool-poolcop-knx/).
- [Export the addresses to ETS](https://wiki.can-nx.com/en/guides/pool-knx-ets-export/) as a CSV file.

**Automate and supervise**

- [Control the water temperature](https://wiki.can-nx.com/en/guides/pool-temperature-control/) by hysteresis, with a KNX sensor and actuator.
- [Set the options](https://wiki.can-nx.com/en/guides/pool-options/): status sending period, resend on request via KNX and a watchdog sent every minute.
- [Connect a non-KNX supervisor](https://wiki.can-nx.com/en/guides/pool-tcp-client/) over TCP, port 50000.

## Good to know

- The type of pool determines the whole configuration: changing it erases the credentials, addresses, options and temperature control.
- A command runs as soon as its row has an address, even if its **Active** box is unticked: clear the address of a command you want to disable.
- With an active filter in a table, only the displayed rows are saved.
- With PoolCop Cloud, a command can take up to about two minutes to appear in the statuses.

## Troubleshooting

[Pool’nX questions and troubleshooting](https://wiki.can-nx.com/en/guides/pool-help/) answers frequent cases: greyed-out button, empty pool list, PoolCop key rejected, status missing from the bus, command with no effect, ETS export blocked.
