I will build raspberry pi industrial iot gateway with modbus mqtt and node red

Need to connect a PLC, meter or machine to an IoT dashboard, but Modbus data is not reaching MQTT reliably? I can build a Raspberry Pi industrial IoT gateway that brings equipment data into one monitoring workflow.

I can set up Modbus RTU over RS-485 or Modbus TCP, publish readings via MQTT, and create a Node-RED dashboard suited to your device and register map.

I OFFER

Raspberry Pi gateway setup

Modbus RTU/TCP integration

Register mapping and value conversion

MQTT topics and payloads

Node-RED flows and live dashboard

Machine status and threshold alerts

Basic data logging

Connection troubleshooting

Reconnect and error handling

Auto-start configuration

PLC, meter and sensor monitoring

Broker/cloud endpoint integration

Hardware or simulator testing

Source files and setup guide

CSV data export for reports and analysis

Useful for equipment monitoring, energy or water measurement, and industrial IoT prototypes. Scope depends on your hardware and documentation; safety-critical control or plant commissioning needs separate revie

Inbox me with your model, device/PLC model, Modbus type, register map and monitoring goal. Ill review the requirements before you order.
