Some great details provided by a student reporter:
> Edward Cenedella, the Director of Facilities and Operations for the Hampden Wilbraham Regional School District, says that the issue is more complicated than just a computer server problem.
> When the high school was rebuilt in 2012, an energy conservation software was added which relied on a daylight harvesting system for the lights to use daylight to equalize the light in the room. Cenedella estimates that there are about 7,000 lights in the building, all of which individually send information through wires to a computer which determines how much light to keep that particular one on. This system is owned by a company called 5th Light.
> “On occasion, the software would go down and it would somehow get corrupted. We would try to recycle it and eventually everything would come back on,” Cenedella said. “Unfortunately the last time it got corrupted it was unfixable.”
> Gaining access to the software that runs the lights is one of the main reasons why the lights can’t be adjusted correctly. “[5th Light] no longer has any of that information. They don’t have the software,” Cenedella said. “The old information is proprietary, so they wouldn’t originally give it to us. Now, they say that they don’t have it and that it’s unavailable.”

- yencabulator 4y agoIn the Home Assistant world, the thing that is inaccessible here would likely be a proprietary box controlling a bunch of relays and LED dimmers, that stopped responding to its network API.
- Nextgrid 4y agoIt would be very easy to replace a relay box though. It would probably cost less to use a bunch of off-the-shelf relay boxes and Home Assistant than pay the new company for whatever they’re trying to do. Better yet, it’s something the school’s technology-focused classes can do as a project.
