Android + Raspberry Pi

Over the years, we found that the most convenient hardware configuration is: Raspberry Pi running the core, and Android running the remote control app. Read more...

Back in 2000, there was a family with a newly acquired tri-level house in Phoenix, Arizona with just a little problem: freezing downstairs, scorching upstairs. Quest for a solution lead to a sad realization that there was nothing that was suitable to solve this problem, not even speaking about anything affordable. A tough decision to go the DIY route was made, and the DIY Zoning Project was created, with the ambitious goal to beat existing systems by feature set and price. The path was difficult, but in a couple of years the project has firmly established itself on the first page of Internet search for "temperature zoning", and as of about 2006 it has become the link of reference, above all companies, big and small, that actually do this for living.

Since 2005, the DIY Zoning Project was in hibernation, for it just worked. By fall 2009 the need to keep it current came up again, as hardware running this project at people's installations started aging and dying, and bit rot kicked in. It was decided that a total overhaul was necessary, since the world has moved on.

During the second phase of requirements analysis phase it has become clear that the project has outgrown the initial scope of a "temperature zoning" system, for in its revised state it can do so much more than just that.

So let's put the stake into the ground and declare that today, on November 17 2009, the new goal is set: this site needs to become the link of reference for the Internet search on home climate control, and whatever else we deem to be relevant to the task at hand along the way.

Laugh all you want, we've done it once already.

Because we feel your pain, for we've been hurting, too. And we're here to take care of that pain, so it is no more.
