Poolcontrol

SIMPLY. MORE. BEGEISTERND.

We would like to thank our guests for the positive feedback at the Aquanale trade fair and at Fira Barcelona!

The sales launch for the Yellow Poolcontrol is planned for April 2026.

Yellow Poolcontrol wins Golden Wave Award 2026 in the Usability category

Our Yellow Poolcontrol was honored with the renowned Golden Wave Award 2026 in the Usability category. The innovation award is presented by the trade magazine SCHWIMMBAD+SAUNA and is one of the most important awards in the pool and wellness industry in the German-speaking region.

The jury particularly recognized the consistent focus on user-friendliness: Yellow Poolcontrol impresses with intuitive operation, clear structures, and efficient control in daily use - both for pool builders and end customers.

The ceremonial award presentation took place on March 27, 2026 at the Rulantica water park in Europa-Park Rust and provided the ideal setting to honor outstanding innovations in the industry.

The Golden Wave Award is presented every two years and recognizes innovative products, technologies, and methods that sustainably shape pool and wellness construction.

We thank the jury for this special recognition as well as our entire team, which with great dedication and passion worked on the development of Yellow Poolcontrol worked has.

“This award confirms our claim to make complex pool technology as simple and accessible as possible Yellow Poolcontrol "This award confirms our commitment to making complex pool technology as simple and accessible as possible. With the"

Interface Mapping Documentation

# Interface Mapping Documentation - Yellow Poolcontrol

This documentation describes the data points for the external interfaces **MQTT**, **BAOS (KNX)**, and **Modbus TCP/RTU**.

## Addressing Scheme
- **Modbus:** All addresses are holding registers (4xxxx).
- **BAOS (KNX):** IDs correspond to KNX object numbers.
- **MQTT:** The base topic is configurable (`mqtt_topic`, default: `Netplus`).
- **Scaling:** Analog values are transmitted as integers. A factor of 100 means the value must be divided by 100 (e.g., 720 -> 7.20).

## MQTT Behavior

### Topic Structure
- **baseTopic:** Please refer to the MQTT settings of your device for the base topic (default: `netplus`).
- **State topic (read):** `/`
- **Command topic (write):** `//set`
- Example: With `baseTopic=Netplus` and `topic=flag.system.enable`:
  - Read: `Netplus/flag.system.enable`
  - Write: `Netplus/flag.system.enable/set`

### Payload Format
- Encoding: UTF-8
- QoS: `1`
- Retain: `false`
- Boolean values: `true/false` or `1/0` (incoming `true` or `1` is interpreted as `True`).
