Project Haystack

Where the Project Haystack community comes together to connect, innovate, and shape the future of smart buildings and IoT.

Haystack Connect 2027 is the premier event for professionals driving innovation in building automation, smart buildings, data interoperability, and the Internet of Things. Organized and produced by the Project Haystack Organization, this annual gathering brings together industry leaders, technology providers, system integrators, consultants, building owners, and end users from around the world.

Whether you're looking to discover new technologies, strengthen industry relationships, share your expertise, or uncover new business opportunities, Haystack Connect is the place to be.

In this session from June 10, 2026, the Project Haystack Labs working group shares the latest progress toward Haystack 5 and explores how community collaboration is accelerating advances in semantic modeling for the built environment.

The Haystack Labs working group has been on a roll. Over the past couple of months, a series of commits to the Xeto GitHub repository have landed meaningful advances across multiple domains — from valve and damper modeling to AC power normalisation to a brand-new proposal for modeling motors and VFDs. Here's a quick roundup.

Project Haystack’s webinar, “Haystack 5 and Xeto for Python Developers,” led by Rick Jennings (SkyFoundry) and Scott Muench (J2 Innovations), delivered a fast, focused walkthrough of Haystack 5’s major new capabilities—especially how to use them hands-on in Python.

This webinar from July 23, 2025 emphasized the critical role of metadata validation in achieving true interoperability in smart buildings. Xeto, a new open-source tool and specification repository, was introduced as the foundation for Haystack 5’s next-generation capabilities.
