The Original Wattmon
The original Wattmon is no longer being produced, and is only partially supported. They are still in use by some, I'm sure, but they are no longer available.
Note that most but not all of the uPHP software reference information documented elsewhere in this Wiki applies to the original Wattmon. However, it had much older versions of the firmware and operating system, which were brought into the WattmonPro and improved.
User Manuals
For those of you who might yet be using the Original Wattmon these User Manuals are helpful:1)
- Installation Manual (Archive, written for the Original Wattmon, November 2014)
- Installation Manual (Archive, written for the Original Wattmon and the WattmonSolar Package, July 2013)
The Wattmons that are Currently Produced:
- The WattmonPRO was introduced next, as a more flexible device with multiple interfaces, built in I/O ports and 128KB RAM.
- The WattmonMINI is 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.

These User Manuals are somewhat “dated,” having been written during times when the newest 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 PRO and MEGA.
