Keen Smart Home Vents

@damohabir, yes, that’s the way the device works…You have to get used to it.

For anyone in the future that reads this, here is a place you order a custom made adapter that converts 6 x 12 vent to fit a 6 x 14 port

It cost me ~$5 after coupon and ~$7 in shipping cost for total of $13, ships from oakland, ca

Here is my problem with the App. I got your app today from your site. Let me tell you, i think this not what i need unless you can tell me how to configure it. I need a very simple setup. I have one Keen Vent that i would like it to open and close based on the temperature reading from the motion sensor in that room. Ex, the sensor read 74 open vent all the way, close sensor half way at 70 close completely at 67. i do not have a thermostat connected nor it was my plan to link the vent to it.

Hi,

As posted at many threads, the ScheduleTstatZones smartapp was designed for some specific use cases as described at:

http://thingsthataresmart.wiki/index.php?title=ScheduleTstatZones#Configuration

Based on your requirements, it looks like ScheduleRoomTempControl would be a better fit.

http://thingsthataresmart.wiki/index.php?title=ScheduleRoomTempControl

(except for the mid-level at 70 as there is only one temp threshold for cooling and heating which means
the smartapp either closes or opens the vent at 100% only).

If you want to switch to ScheduleRoomTempControl, I can then partially refund you for your contribution to ScheduleTstatZones after you buy ScheduleRoomTempControl at my store.

P.S. Also, please send me any further request to services@maisonsecomatiq.com as I’m not always in the ST forum and it’s easier for me to follow customer requests thru gmail conversations.
Regards.

@yvesracine, I am looking for something similar to what @mssidah is looking for. My thermostat is not connected to SmartThings. I need simple control of the vent based on the temperature reading in the room. Can one of your apps do that without using a thermostat connection?

Yes, ScheduleRoomTempControl can control the vents without a thermostat (it’s optional).

Please refer to the ST community wiki for more details:

http://thingsthataresmart.wiki/index.php?title=ScheduleRoomTempControl

I have also a dedicated thread for my zoned heating/cooling solutions.

Regards.

I you have no thermostat in ST, the vents can be directly controlled using rule machine. They appear as dimmers, where the dim level represents the % of opening.

So, anyone get the crazy whistling sound when the vent’s closed? Any way to resolve that?

only fix i have found is opening them. If they had thought through their design they would have put rubber edges on them so they could fully close without whistling or making that nice rattling sound. Wait maybe a good mod in my future

Yeah, I’ve found that keeping them fully closed doesn’t work, I would have to make them 50% open to actually get rid of the noise.

Hi @damohabir,

The benefit of using my smartapp is that if your requirements evolve later (for example: you may want to orchestrate and control your thermostat(s) in conjunction with your vents), then ScheduleRoomTempControl will make it possible.

In my book, the vents should be controlled in conjunction with your thermostat setpoints to reach maximum comfort and energy savings. You can use schedules to control them differently during the day.

It also simplifies your setup as you then have 1 single smartapp that orchestrates your thermostat setpoints & your vents based on your motion and temp sensors in your rooms. It’s much more logical and convenient.

Regards.

I just installed some keen vents and I have an issue. When I set my vents at at particular level they change to a lower value by themselves often by about 5 other times more. Most of the time they only change once to a lower value but other times they change twice by themselves. I already looked at the logs in the IDE and it doesn’t provide me with anything helpful at least as far as I can tell. In this what happened when I changed the vent to 75. It changes ok to 75 but after a few seconds it changes to 66%. Any idea what could be causing this. At one point I removed all smartapps associated with it and it still did the same thing…

@Cullen_Patel
This is normal for these.
The mechanism in the vents that provides level feedback is an analog potentiometer attached to the shaft that actuates the vents.
So the DTH sends a set level xxx to the vent, this causes the vent to return a report (from 0 to x seconds later) of its actual position, given the mechanical play and ADC rounding, the result is almost never the level you sent it to.
The offset (set to reported) is also not consistent.

I have found the following to be true for all 10 of my vents
setLevel(0), vent reports 0
SetLevel(100) vent reports > 92, but never 100
Anything else will vary by +/- 5%

Anyone know any way of sealing the vent so when closed, it doesn’t make the horrible hissing noise? It makes the thing nearly unusable…

Nomisr, I have that same issue with one of my vents, I actually changed it with another and even though it still makes the noise, it is not as bad. I have it set now so that if there is motion in that room, it sets the vent to 5% instead of closed. It still blocks off most of the air but doesn’t make any noise at that level or as @Mike_Maxwell! (thanks a lot for the info btw!) pointed out, at about that level…

I have been toying with the idea of getting some rubber vacuum hose from the parts store and cutting a slit in it so I can wrap it over the end of the blades to see if that helps with the hiss

Not sure of the cost difference but try door edge molding…you know, the stuff people used to put on the edges of their doors so the paint didn’t get chipped if you bumped something opening your door?..I believe it comes in clear even…pre-slit…just trim to length ;)[quote=“keltymd, post:486, topic:5826, full:true”]

Did Keen ever follow up on creating a device handler for their hub to act as a repeater?

Does anyone have a device handler that will allow the Keen hub to act as a repeater?

Hi everyone! Sorry we’ve been quiet on this forum. We’ve been supporting our own customer support line. It looks like many of you are experimenting with fit-kits to get Smart Vents to work with other sizes. I love this community.

We’re experimenting with fit-kits that help expand sizes too. Right now, we have a kit to convert 8x10 ducts to fit a 6x10 vent and a kit to convert 6x14 ducts to fit 6x12 vents. The designs are finished be we have not added them to our shop.keenhome.io store yet. You can get them made for you on ponoko.com in a material of your choice.

To get one made:

  1. See the file here: http://www.ponoko.com/showroom/KeenHome
  2. Click on the design you need
  3. Scroll down to click “Add to personal Factory”
  4. Create an account and go to “my designs” to view
  5. Select a material to have it made in (I recommend white melamine for a strong, thick material, or Matte White acrylic for a closer color/texture match)

Let me know if this works for you or if you need help. I’ll post more designs soon

Best,
Will

Hi Will,

Has there been any progress on creating a device handler to allow your hub can act as a repeater?
