The field challenge

The challenge on site

When meter readings sit in different instruments and formats, it is hard to build a consistent view of consumption. Connect the meters you already use, map their registers and make communication status visible alongside each reading.

Engineering reference design. Final equipment, functions and pilot checks are agreed for your site.

Integration approach

What the first pilot includes

  • Read agreed totals, instantaneous values and device status.
  • Record units, scaling, byte order and timestamps against the register map.
  • Send validated data to the customer’s broker and application.
PILOT CHECKS

What a working system should demonstrate

  • Compare a known register with the displayed value and unit.
  • Show the timestamp and distinguish a fresh reading from a communication fault.
  • Verify reconnection and data delivery after a controlled network interruption.
PROJECT INPUTS

What to share with our team

  • Meter models, register map and electrical interface
  • Point count, polling/reporting intervals and data-expiry rules
  • Bus layout, power, isolation and grounding
  • Broker ownership, payload, TLS and storage requirements

Installation & power

Plan the physical connections.

The reference separates data paths from supply wiring. Confirm actual loads, protection and installation conditions.
