Wattmon is a flexible and easy-to-use device that merges three functions: Data Logging, Automation and Remote Monitoring with versatile applications.


What does it do?
Wattmon collects and stores data from batteries, meters and sensors, and displays the information you need through intuitive graphs on your mobile, tabled or PC. In addition, Wattmon can automatically control things or send emails via triggers based on various criteria such as available energy.  Wattmon helps hybrid setups maximize their use of renewables.

I don’t see anymore how it is possible to manage a solar system without the full monitoring and control provided by Wattmon, it is a small investment that makes the big one - of the solar system - finally 100% worth its value.

I am very happy to be using a Wattmon; it is very practical and controls the charging, from the mains, of my battery bank during the night time, whenever the battery charge level falls below a certain level and stops the charging when it reaches another level. All these parameters are programmable and can even be managed remotely. As a result I believe my battery will have a longer and better life than otherwise. The Wattmon is being continuously improved and upgraded...it's a very necessary accessory to your solar power system.

We have been impressed by the flexibility of the Wattmon, its simple programmability enabled us to use it for a complicated application that would otherwise have required designing our own device.
