Meters & Metering Systems

Smart Meter (SMETS2)

Key takeaways

SMETS2 is the second generation of smart meters under the SMETS standard.

SMETS2 uses the secure DCC smart data network, rather than relying on mobile signal in the same way as SMETS1.

What does SMETS2 mean?

SMETS2 is a smart meter built to the second-generation SMETS specification.

It’s widely treated as the current standard smart meter type under the SMETS framework.

How SMETS2 communicates

SMETS2 meters communicate via the DCC (a secure smart data network), which is the key technical difference compared with SMETS1.

Why SMETS2 matters for businesses

For most businesses, SMETS2 is mainly about:

  1. reliable automatic readings
  2. better continuity of smart functions (especially when switching supplier)
  3. more consistent usage data for cost control
