## Multiple Connections

Modbus is designed to mostly have a single Master.

If you try to connect multiple instances to the Inverter ie this Integration and Node-RED the Inverter will either block the second connection or likely to result in data collisions.

If this happens it's recomended to use a multiplexer such as https://github.com/IngmarStein/tcp-multiplexer this has been tested by reading and writing from two instances of HA at once.

This can be started with Docker or Docker Compose.

Example Compose:

```

services:

  modbus-proxy:

    image: ghcr.io/ingmarstein/tcp-multiplexer

    container_name: modbus_proxy

    ports:

      - "5020:5020"

    command: [ "server", "-t", "192.168.123.123:502", "-l", "5020", "-p", "modbus", "-v" ]

    restart: unless-stopped

```

Server address is the Inverter / data logger.

You then direct this integration to the machine running the proxy and port 5020 in this example.
