With over 35,000 operational devices in Australia and internationally, Auditor 6M by Wattwatchers is a popular enterprise-grade energy monitoring choice. The Auditor 6M provides real-time, Class 1-accurate data with options for switching control (6M+3SW) and billing solutions (6M+One).

Equipped with built-in cellular communications, the Auditor 6M allows users to effortlessly harness the power of data and future-proof investments. It’s a turnkey plug-and-play electricity monitoring solution, which is suitable for residential, commercial, and industrial applications. It integrates with dozens of third-party software solutions, including solar performance monitoring, load shifting and control, home energy management, commercial sub-metering and more. Or you can access data via our easy-to-use, thoroughly documented, and secure API to design your own solutions.

How it works

The Auditor 6M is installed in electrical switchboards, where it captures electricity flow data at individual circuits level and securely transmits it to the Cloud.  From there users can access the energy data - both real-time and historical - on computers, tablets and smartphones via our REST API, the Wattwatchers Software Toolkit (including the MyEnergy mobile app), or third-party interfaces. Installation always requires a licensed electrician.

Our top tip to get started is to make sure you order the correct equipment:

  1. HOMES: For monitoring-only in homes this will mainly be one device and two sets of standard 60 amp CTs, but we recommend sharing a digital photo of your switchboard contents with your electrician to get any additional advice. 
  2. C&I: For commercial and industrial sites, there is much more variability, especially in CT numbers and sizing, and pre-scoping by an electrician is recommended ahead of finalising equipment orders with Wattwatchers.
  3. OPTIONS: If you are seeking to use Auditor 6M variants for the first time - such as the Auditor 6M+3SW for monitoring plus control, or the Auditor 6M+One for behind-the-utility-meter billing (e.g. solar power purchase agreements) - discuss your needs with us via


National Measurements Act 1960 mandated utilising NMI-approved technology for trade in Australia that includes 'behind-the-meter' energy billing or power-purchase-agreement (PPA).

It's illegal to use anything (from Wattwatchers inventory) but the Auditor 6M+One for trade or billing purposes.
