Keen Smart Home Vents

My problem is not that the vents are not closed but they never open fully even if temperature in the room is far below the threshold (for instance - the room’s current temp. is 65 and my heating threshold to keep the vent open is 72 and my desired temperature is 70) and i would expect the vent to open fully or to be close to 100% opening to let the hot air in the room. In reality the vent floating between 25 and 35% at the best. Moreover my furnace is working more frequently now.

Well, I tested a similar use case yesterday at my home with the latest version and it did set the vents at 100%.

The ScheduleRoomTempControl smartapp will either close (partially) the vents or leave them open at 100%. Yesterday, I added an option to close the vents totally if you want to bypass the safeguards.

Please make sure to have the latest version by copying the code from github, saving it & publishing it in the IDE.

If it’s still not working, you’d need to activate the IDE live logging and PM me the logs. I will then have to charge you a support fee as I have a full time job and support (as you may know by now) takes too much of my time.

Please refer to item no 3 (under troubleshooting) for your own troubleshooting.

I hope that you’ll understand my position.

Bye for now.

We aren’t currently making baseboard vents, but we get this question a lot. Our plan is to make additional sizes next year based on what sizes are most desired. Be sure to subscribe to our mailing list here to get the latest sizing updates.

Thanks, Nate! I’ve signed up!

Thank you, I was about to update the freakish 4-sec polling intervals and give that a shot when I noticed your post. Will use your dev type instead.

Is it at all possible to remove/un-publish the default template such that when I discover additional Keen vents they default to say your Device Type rather than the S.T. published version? That’d be great, but I can’t quite figure out how to accomplish that.

Yes, it’s possible, create the device type using my code and rename it to the default name, which is

Keen Home Smart Vent

And that should do the trick. I didn’t want to replace the default template by default.

And, please support the developer :grinning:

So from this thread I’m hearing concerns regarding viability of the pressure sensor unless used with keen hub rather than a SmartApp as well as need for external temp sensors versus the embedded one. Is that the general consensus, that these features are more marketing than practical? Anyone have the keen hub and know how well it’s magic compensates for the issues @Mike_Maxwell and @yvesracine via the keen engineer bring up?

Yes I’m curious about the temperature sensors too… whether or not we’ll need separate ones.

Hi @scottalex, the Keen Home Hub has not been shipped yet, so I cannot comment about the hub.

About the sensors:

(1) The pressure sensors are not useful now, as per my previous posts on this topic

(2) The temp sensors cannot be used for HA scenarios except for the one I do use in my smartapps, which is to control that the vents’ temperature are within an acceptable range to avoid any HVAC damage.

As of now, the temp sensors cannot be used to get the ambient temperature as they are affected by the airflow.

Regards.

It would be very nice if Smart Lighting would be able to incorporate the vent capabilities. :slight_smile:

While I agree, it will take a fairly sophisticated smartapp to manage these properly and smart lighting currently does not possess the requisite skill set.

Hi Yves,

Is ecobee3RemoteSensorInit required for ST presence sensors integration into the ScheduleRoomTempControl smartapp so that the thermostat will read from different locations to average the temperature or this feature already has been embedded into ScheduleRoomTempControl? It seems like the ecobee3 has no clue what is going at other zones.

Hi @apropo73,

ecobee3RemoteSensorInit is only required if you have ecobee3’s remote sensors that you want to expose to ST and use them for your HA scenarios.

ScheduleRoomTempControl does not average any temp, only ScheduleTstatZones or ecobeeSetZoneWithSchedule do the average temp calculation within a zone.

ScheduleRoomTempControl was created to just control the vents based on each room’s temperature within a zone vs. the cooling and heating thresholds.

It is used for the different use cases described at the ST community wiki under the configuration section:

Regards.

Thanks for the prompt reply!
If so, which one of the two smartapps would you recommend to use if I am interested to set different heat/cool setpoints for different zones/schedules and not to let my ecobee3 to override it, ScheduleTstatZones or ecobeeSetZoneWithSchedule ?

@apropo73, what do you mean by " not to let my ecobee3 to override it"?

I’d recommend to use the ecobee climates (or ecobee scheduled programs) as much as possible as the ST scheduling is not as reliable as the ecobee scheduling…

You can then make adjustments to your setpoints using ecobeeSetZoneWithSchedule by associating the smartapp’s schedule to a given ecobee climate. The smartapp is able to average out your temp based
on all temp sensors within a zone.

Please carefully read the use cases at

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

That’s what I do at home,and it works well.

Otherwise, if you still want to rely on ST scheduling, then ScheduleTstatZones can be used, but you’d need to go to the ecobee portal, and clean & set the minimal settings in your schedule to avoid any overlap. The smartapp will then create a “hold” at your thermostat by applying the schedule’s setpoints.

EcobeeSetZoneWithSchedule is more designed towards ecobee thermostats as it can do ‘resume program’ to avoid successive holds…

As I said earlier, if your use cases are “custom”, I can help you but I will have to charge you a consulting fee.

Regards.

I’m still trying to sort it out on my own. Thanks

For those who were interested in fitting a 6"X10" keen vent into a 8"X10" vent opening, see this pic. I tried something rough to see how it looks … The finish is not so good…screwed up the joints of the frame… But I think this is a good solution. I made a wooden frame and used Window seal to ensure it has a snug fit against the ceiling, so that air does not leak. Painted using gloss finish white spray paint to match the plastic. If you ignore the poor craftsmanship of the joints…this seems workable. When I close this vent (30%) , I get better air flow in my master and it gets warmer faster…due to this I am able to set my thermostat to Heat of 70 instead of 74 earlier…The thermostat is located right under the smart vent…:slight_smile: Mission Accomplished!

Will be trying for the second vent…but will make the frame with the right tools this time and with precision. Hopefully it will have a better finish.

Hi,

Please take note of the following thread:

P.S. The ScheduleTstatZones,ecobeeSetZoneWithSchedule & ScheduleRomTempControl smartapps will be only available to those who contribute with a donation. Thnx for your understanding.

How do you get these to factory reset? I tried ejevting the battery 5x like the FAQ says but no success

I installed three Smart Vents this weekend, and with the latest updates from Samsung and yvesracine, all is working well.
However, for those of you looking for simpler solutions than yvesracine’s HVAC-centric apps, I’ve been very happy with bravenel’s Rule Machine.
It’s now driving two Keen registers that close when a temperature threshold (measured by Ecobee 3 sensors) is exceeded, and open when the rooms cool, and the third vent, in my BR, is automatically closed 11 hours/day based on time (unless the room is below a minimum).
For me, the Rule Machine app is simpler to set up, as it doesn’t force you through the complexity and setup for Zones and Rooms, just a simple If This, then do That or The Other.
The other reason I’m using Rule Machine instead of ScheduleRomTempControl is that it Doesn’t try to protect the user’s HVAC system: I have one register about 4 feet from the furnace - the air comes out Hot. The ScheduleRoomTempControl app noticed from the vent that the airflow was 127F, and tried to open all the other vents to relieve imagined insufficient airflow.
I’ll be curious to see the Keen app, but you certainly don’t need it to make effective use of the vents.
I’ve noticed one very cool feature: if you go to the Vent Thing, there is a red slider at bottom left that sets the % of Vent Open. If you set it there, and then Close the vent there, when Rule Machine turns the Vent to On again (i.e. opens the vent) it will be opened to the amount you set in the thing, and it stays set.
