Links from the August 2008 Central Ohio .NET Developers Group meeting:
The presenters were from Exceptional Innovation. They discussed the use of Devices Profile for Web Services in their home automation products. After the presentation we were given a tour of their office which includes a model living area where they can demonstrate many parts of the system.
Also, I was not aware that there are different kinds of twilight: Civil Twilight, Nautical Twilight, and Astronomical Twilight. This came up in the discussion on programming their Life|ware system. I can't recall now if their system included Nautical Twilight. It should, for the yacht automation market, you know.
And thanks for the pizza.
