@McCroden We are planning to simply build floor models that just replace your existing floor vents. It needs to be flush and strong so that you can't put a chair leg through it.

@dandroid88 Do you think it might be simpler to use existing vent cover and make something go on the inside of the vent? I just know a lot of people that choose floor vent covers to match the floor material. Ex: wood floors have matching wood vent covers.

@McCroden Thats an interesting idea and totally have seen decorative floor vent covers. We are mostly focusing on the ceiling models for the initial push so we will keep this suggestion in mind no doubt. Thanks for the feedback, we will take as much input as possible!

@dandroid88 For sure. One last thing: My dad is a carpenter. Any house that we have built only ever had ceiling air vents in basements. Maybe it's just a midwest thing, but may be worth figuring out what the market actually is for that. $0.02

@McCroden absolutely. We have done a fair amount of surveying and collecting stats but without a doubt its a mixed bag and its geography dependent. Our findings are that generally floor vents are more common in places where heating is the priority and ceiling vents are quite common in both warm and cold places.

@ryan my initial thought verbatim @dandroid88 If you save more energy, it seems like you are making a biz case for this over Nest? Are there any downsides to the UX? Will this cost more?

@EAWharton There is some case for this over nest but really we see it as a compliment to nest. They expose an API to your furnace, AC and blower motor. We build on that for more significant energy efficiency gains. I'm sure you could come up with downsides regarding UX but we could also come up with upsides. Lower energy bills and more granular control seem like a better experience to me. Having a single temp sensor in a hallway is a pretty lacking UX for a complex structure. We have a responsive web UI will build native Apps on top of our APIs. Lastly, we are using some cool tricks for occupancy detection hence after you set your desired temperature for rooms, it should just work in the background.

@jfrankel13 We are tracking the on-time of the system in order to measure system efficiency. The idea is that on-time is a cost function (in the machine learning world) which can be optimized. Effectively, we can make configuration adjustments and figure out how to minimize on time while satisfying your temperature requirements. We are also being careful to play nice with older systems. For instance, we have pressure sensors that can tell when the system pressure is too high and hence too many vents are closed at any given time. We don't want to stress your system, in fact, we want it to run less hence make it last longer while saving you money. Lastly, and I made a similar comment above, think of it as dynamic balancing rather than strict zoning in the traditional sense. All registers are made to open and close with good reason. We are just automating this process for comfort and efficiency.

@dandroid88 product page is very opaque. How would you implement "microzones" without a multi-zone HVAC system?

@ryan The video on the page shows a vent cover magnetically attached to the actual vent cover. The flair cover will, I'm assuming, get a signal from a central unit to close or open the vents. Thereby creating different zones.

@McCroden ah! I think I opened the page on my iPad, and did not see there was a video. Probably why I got the impression the site was opaque.

@ryan Yeah, but I was on my MBP and didn't catch the video on my first scroll-through either.

@ryan I would suggest thinking about it more as dynamic balancing. Essentially, we are routing the air by biasing vents in occupied rooms and by temperature gradients. All registers already have a close/open mechanism. We are simply automating the open/close/adjust to waste less and ensure satisfactory localized climate control. It is also respectful of single speed blower motors (not closing too many at once as indicated by pressure sensors) and self optimizes by tracking system ontime and minimizing it while satisfying comfort requirements.

@dandroid88 Yeah, the battery claim is very impressive. Also curious to know how you handle onboarding/initial device setup (presumably you have to get everything on wifi?). That always seems like a UX hurdle for connected devices.

@adamsigel If you are familiar with how chrome does it, thats what we are thinking for wifi only setups. Ethernet is a bit easier. FYI, we have a base station(s) which is coordinating the system. As far as each vent we currently have them self register with the base station and then you simply assign them to user created rooms. Agreed that it is a tripping point for a lot of connected devices.
