Zap P1-meter Compability

The Sourceful Energy Zap can connect to your smart meter in different ways depending on your meter's interface. Here's what you need to know about each connection type.

We've created a guide to help you identify your connection type, but for absolute certainty, we recommend contacting your utility company about if your meter has RJ12 or RJ45 connection.

Standard P1 Connection (RJ12)

Most Common Configuration

  • Standard port interface (RJ12-port with 6-pin) on most modern smart meters.
  • Works immediately out of the box. No extra adapter needed.
  • The Zap draws all needed power directly from your smart meter - no external power supply needed.

Example of meters with Standard P1 port (RJ12):


Meters Requiring Adapters

  • Specific to Kamstrup Omnipower meters
  • Requires Sourceful Kamstrup Adapter - no external power supply needed.

RJ45 Connection (8-pin)

  • Found on some smart meters. Common in Norway.
  • Requires Sourceful RJ45-toRJ12 Adapter
  • Standard network cables will not work
  • Check your specific meter model for compatibility

How to Identify Your Connection Type

  • Often behind a small cover
  • Typically labeled as "P1" or "User Port"
