# Integrating Janitza meters with CLEMAP

CLEMAP supports reading data from Janitza meters (e.g. UMG 96RM-E, UMG 604, UMG 512) via **Modbus TCP**. The measurement data is transferred directly from the Janitza device to the CLEMAP platform.

## Requirements

For the integration to work, the following points must be fulfilled on the Janitza device:

- **Communication protocol:** Modbus TCP active
- **Modbus slave address:** must be set to `1`
- **Network:** The Janitza device requires a **fixed IP address** and must be reachable from the network in which the CLEMAP device is also operated
- **Port:** Standard Modbus TCP port `502` must be reachable (open firewall if necessary)

## Checking the settings on the Janitza device

The configuration can be verified directly in the web interface of the Janitza device:

1. Open the Janitza device's web interface in your browser (via the IP address)
2. Select the menu **Information**
3. Expand the section **Communication**

The following values must be visible:

- **IP address** – fixed IP address
- **Subnet mask** – matching the network
- **Modbus slave** – must be set to `1`

:::BlockQuote
**Note:** If the Modbus slave is not set to `1`, CLEMAP cannot read the device. The value must be adjusted before the integration.

## Integration by CLEMAP

The integration of the Janitza device into the CLEMAP platform is carried out by CLEMAP. Self-configuration by the customer is not provided.

**Please contact us with the following information:**

| Information                  | Example           |
| ---------------------------- | ----------------- |
| Model type of Janitza device | e.g. UMG 96RM-E   |
| IP address of the device     | e.g. 192.168.1.50 |
| Modbus slave address         | 1                 |

CLEMAP will then take over the integration and configuration on the platform. After successful integration, the measurement data is available in FLOEM.
