Keen Smart Home Vents

Just went in an start the adding new device and it showed up as a thing with a zigbee id. I don’t speak zigbee so I have no clue if it’s actually repeating anything…

@Mike_Maxwell I have an 8 vent system too and would like to join the beta test as well!

Thank you. Looks great. Are there any suggestions on specific temperature sensors? We already have a security system with sensors on all of our windows and doors so not in need of a multi sensor like SmartThings produces.

@yvesracine - looking at the screen shots for the app you created is there any way on a single screen to see the current temperature and set temperature for each virtual zone with the ability to temporarily override?

@pfeifer, you can use the SmartSense sensors or others. Personally, I use the wireless tags ( and I love them! I have 8 of them at home for my main rooms.

The current smartapp does not allow to see the current temperature for each zone; you usually execute it only to configure your rooms, zones and schedules (with your setpoints and fan settings), and then it reschedules itself for applying your zone settings at the right time.

You can run the app manually anytime to apply your schedule and zone settings at a given time.


They look awesome but what wireless technology do they use? A little spendy though…

More details here:

Well, the price is not so bad: $30 for temperature & humidity in a very small package. You have to pay for the hub ($45) also.

The ST integration is also very reliable:

The Fibaro Door/Window sensors are very nice. They report temperature in fractions of a degree, and send the data to the hub when the temperature changes by .25F The sensors are quicker to respond to changes than others, and are reported to be more accurate than other brands. Net is that temperature can be controlled very well with these.
They are also tiny and come in several colors to match your decor.
The only downside is that you have to install a small temp sensor chip inside them yourself (Involves bending/clipping three small wires to fit under connecting screws in a small space.)

The HSM200 are real nice. Zwave and plug in so they can send data all you want. They are pricey but they work well

Except for the fact that I don’t have power outlets in the middle of interior walls at eye level, I guess those would work.

That’s clever. I did not know they had that feature. Given that these are generally attached to exterior doors/windows, isn’t that a problem? My exterior doors are noticeably cooler than, say, the interior walls of the same room and I expect the ambient air around them is, as well. How did you work through that?

Why do they need to be “in the middle of interior walls at eye level?”

It’s a stretch but maybe because it would be the ‘average’ temperature of the room since heat rises?

I could be wrong though.

I guess in that case you would need to have a sensor suspended by string hanging in the middle of the room? :wink:

If we’re getting really technical, it would also depend on where the vent was as well :stuck_out_tongue:

They don’t, elevation isn’t that much of an issue.
Bad locations are on exterior walls, or under/near a vent.
Temperature is just a number, in the end is the room too hot or too cold?
I’ve not even bothered to calibrate mine, wasn’t worth the effort at this point.

I am using custom SmartSense Motion sensors that are accurate, fast and report at .1. :slight_smile:

Given that these are generally attached to exterior doors/windows, isn’t that a problem?

No, you just stick it up it anywhere you like, use it as a temp-sensor, and toss the door-sense magnet.

You can offset the temp on the sensor. I have a thermometer I take from room to room and calibrate the desire to it. It is place at the point I want so the sensor calibrates to the thermometer location

Yup, just need to pick a consistent placement and I think initial calibration is important if you monitor multiple rooms. If you have two sensors off by +/- 2, then it could be a game changer.

Well, generally, 'cuz that’s where my head is, so that’s where the temperature is most relevant. :stuck_out_tongue:

I understand Mike’s point about temp being just a number, and that you can find offsets that will work. Clearly the HSM200s work. In my house they’d mostly be behind furniture or too close to vents, though. I’ll probably opt for multisensors that I can mount in discrete places and suffer the limitations of running on batteries.
