I am one of the home automation community members who have always been ignored and shunned by a specific segment of the market, and my friends, that ends today!!
The small group of manufacturers who produce smart vents and allow people to have a far greater fidelity of control over their homes HVAC, have together made the decision to punish those brave Americans whose homes were built with 2" x 12" HVAC vents instead of a larger version.
I don't know why it what we did to them, but deserve smart vents too. They tell us that it's not enough room, but we know better. We are the same people who tinker with Raspberry Pi Zeros and break brand new devices wide open to hack them to make then better. If we can put a TB of data on a chip smaller than a pinky-toe nail, we can figure it out. And we will, but I'll need your help.
I know how to break stuff, in fact I'm considered an expert in the field. I am ok at fixing, but when it comes to coding and programming, I'm kinda dumb.
So here's my plans, which are already in motion. I have just ordered a 2" x 12" Vent-Miser 91663 Programmable Vent from my good friend Jeff Bezos, so it should be here tomorrow. This is a vent cover equipped with a digital programable timer which once set, will fully open and fully close its baffles based on how it's set. It does this with a battery powdered DC motor, all of which is contained within the unit (funny how they could get it to fit)
Also on my way is a Z-wave contact sensor which I've used on a few other projects because it has a built in simple open/closed input interface which can be connected to either report a change or trigger a change. I need to get the vent in my hands to see how I'm going to do this, but I'm confident I will be able to configure a simple Z-wave curcuit to enable my Hubitat Hub to open or close a specific vent in a specific room based on a temperature threshold being met.
But if for some reason I have to code or program something, I'll need help. Otherwise I'll become sad and cry.
Anyway, as I work, I'll post here for any suggestions or words of wisdom you may have. But to a greater extent enable those people who have suffered as I have a at the Amish Shunning we've we endured by the Smart Vent industry will need to suffer no more!
