How to connect a Modbus electricity meter to a cloud dashboard

A practical, step-by-step guide to reading a Modbus RTU or Modbus TCP electricity meter with a gateway and sending the data to a cloud database and dashboard.

Industrial IoT

Modbus RTU vs Modbus TCP: which should you use for industrial monitoring?

The differences between Modbus RTU and Modbus TCP — physical layer, speed, topology, reliability and security — and how to choose for meters, PLCs and sensors.

Industrial IoT

How to monitor a standby generator remotely

What to measure on a standby generator, how to connect the controller and fuel sensor, which alerts matter, and how to monitor a fleet of generators across sites.

Industrial IoT

Can an existing PLC be connected to the cloud?

How to get data from an existing Siemens, Allen-Bradley or Schneider PLC into a cloud dashboard without replacing it — the options, the protocols and the security rules.

Industrial IoT

PLC vs IoT gateway: which one do you need?

The difference between a PLC and an IoT gateway, when you need each, and why most modern sites use both together.

Industrial IoT

Industrial IoT architecture explained: sensor → gateway → MQTT → database → dashboard

The layers of an industrial IoT system, what each does, how data moves between them, and how to design for multiple sites, outages and security.

Energy

How energy sub-metering works in commercial property and industry

What sub-metering is, how meters are installed and read, how the data is used for tenant recovery and efficiency, and what to check before you start.

Energy

Understanding 30-minute electricity interval data

What 30-minute interval data is, how to read kWh, kW and kVA from it, and how to use it to find base load, peak demand, after-hours waste and tariff savings.

How to choose your first AI use case in a business

A practical scoring method for choosing a first AI project that pays back — with examples, warning signs and the data and governance questions to ask first.

Software

Custom software vs off-the-shelf: how to decide
