Network UPS Tools
Power Devices support

The primary goal of the Network UPS Tools (NUT) project is to provide support for Power Devices, such as Uninterruptible Power Supplies, Power Distribution Units, Automatic Transfer Switches, Power Supply Units and Solar Controllers. NUT provides a common protocol and set of tools to monitor and manage such devices, and to consistently name equivalent features and data points, across a vast range of vendor-specific protocols and connection media types.

NUT provides many control and monitoring features, with a uniform control and management interface. If you are just getting acquainted with NUT, that page also explains the technical design and some possible set-ups.

More than 140 different manufacturers, and several thousands of models are compatible.

This software is the combined effort of many individuals and companies with free and open source code licensed under the terms of GNU Public License (GPL), see the NUT license text for specific details.

Note
Two NUT websites

The main NUT site is dedicated to the latest release of NUT, to serve as a reference about its capabilities for users of newest official packages in different OS distributions.

There is also a master.networkupstools.org site which should more closely follow current development, for users who build NUT from source code.
