Sedona Alliance Logo with Wiresheet

The Sedona Alliance represents the interests of a community of developers, system integrators, and users promoting the use of the Sedona as an open control software environment. Originally developed by Tridium, Inc., Sedona is a software environment designed to make it easy to build smart, networked, embedded devices which are well suited for implementing control applications. Development of the technology is now being assumed by a Sedona community interested in keeping this open-source technology open for all to use.

The Sedona technology, open-source license, downloadable code and documentation all resided on the SedonaDev.Org site which no longer exists. The Sedona Alliance provides a copy of the original documentation and the Sedona development files on the Sedona Alliance Resources page. Separately, Tridium, Inc. maintained a certification program that allowed companies to use their trademark Powered by Sedona Framework™ for products that passed their conformance test. That program no longer exists but Tridium retains the rights to this trademark and logo and to Sedona Framework™ and their rights should be respected. The Sedona Alliance is not affiliated in any way with Tridium, Inc. and recognizes Tridium's ownership of these trademarks.

The last Sedona release found on SedonaDev.Org was Sedona 1.2.28. Development of the Sedona technology beyond this release is now being assumed by a Sedona community interested in keeping this open-source technology (under AFL 3.0) open for all to use.

The Sedona software environment is ideally suited for graphical representation of control strategies. It has a similar look-and-feel to the popular Niagara Framework® and it is IP-based. Those with experience with Niagara Framework will have no problem understanding Sedona. For those without Niagara experience, the graphical representation of components linked on a wire sheet to create applications is intuitive and can be easily learned with a minimum of training.

The mission of the Sedona Alliance is to promote Sedona as the premier open control software environment available for use by the public without restriction. The Alliance represents the interests of a Sedona community consisting of developers who make Sedona products, integrators that create Sedona applications, and users that benefit from its deployment.

Sponsorship of the Sedona Alliance is by Contemporary Controls that is funding the Sedona Alliance's development and maintenance while contributing technical material to educate the public about Sedona. Others contribute their time and effort without compensation. Participation is open to those who can contribute to the Alliance's mission of making Sedona the premier open control software environment.

The Sedona Alliance's concept of an open controller is one that:

Utilizes an open programming language for implementing control strategies

Sedona is open source, and due to its similarity to Niagara Framework it is familiar to many integrators

Utilizes a programming tool available without restriction

Those without access to Niagara Workbench can use Sedona Application Editor from community member Contemporary Controls or Sedona tools from others

Fosters a community of developers and integrators that share technology for the public good

A Sedona community of developers and integrators exist using the resources of the Sedona Alliance
