WattmonProThe WattmonPRO is a more flexible device than the original Wattmon. It was the 2nd generation to be released in our range of embedded data logging and control devices. Compared to the original Wattmon, this version has several I/O lines on-board and 128KB RAM, making it easier to develop intelligent machine automation applications in addition to performing data logging.

Compared to any of the Wattmons including the WattmonMEGA (the latest and most capable Wattmon), the PRO uses the same OS, and is compatible with the same set of Modules and Accessories. The PRO firmware has the same set of functions but without the code needed for the hardware improvements of the MEGA.

The PRO can be used for any application in monitoring, control and data logging for the IoT. But particularly noted applications include:

  • Inverter Monitoring - Inspect generation and efficiency of gridtie and hybrid inverters
  • AC Power Monitoring - Supervise load and performance of substations and mini-grids
  • Off-Grid Battery Monitoring - Observe battery voltage, current, SoC, charging trends and health over time
  • Zero Export & DG Protection - Reduce active output power of multiple inverters to regulate energy generation

Quick Start Guide

The Quick Start Guide is a regularly updated manual that sheds light on some of the basic and/or essential configuration for the WattmonPRO running the latest WattmonOS version.

User Manuals

The Wattmons that Came After the PRO:

  • The WattmonMINI was released next as a reduced version of the WattmonPRO with a single Modbus RTU port.
  • The WattmonMEGA has 512KB RAM, 100mbps Ethernet, and operates at 200MHz making it over twice as fast as the PRO.
1) These User Manuals are somewhat “dated,” having been written during times when the newer Wattmons had not yet been released, and they sometimes feature or show specific Modules or Hardware that are obsolete (no longer available). However, the OS is the same for all of the Wattmons. Therefore the hardware differences are the only thing to keep in mind when using these manuals, especially the Original Wattmon and WattmonMINI which do not have the additional I/O ports that are provided on the WattmonPRO and WattmonMEGA.
