Works with smart thermostats & conventional thermostats as well as other Smart Home devices.

I haven’t used it yet but the installation and the hook up to my nest was simple ! I turned on the nest and lowered the temperature so it would turn on and the cocoon turned on beautifully and the ac came through perfectly! I’m sure the heat will work the same.
Our house has two rooms with minimal register airflow even after extensive renovations it didn’t make a difference but the smart cocoon register booster fan increased the airflow to make a significant difference in the temperature of our rooms.
It's working well, I will buy a second for another problem room.
Id love a way to control led brightness through the app
Also, when pairing with ecobee, it would be great if you could designate which room sensor covers the smart fan.
But overall I am very happy with the device.
Thank you for your feedback! We’re glad to hear the fan is working well. While we’re integrated with Ecobee, we’re not currently integrated with their sensors. That said, we have some exciting updates coming soon for our Ecobee users, so please stay tuned!
Very good and nice I like this product
Thank you so much for your feedback!
Immediately our room felt cooler. Finally solved the problem in our 3 storie townhouse where it never was cool enough. I might need more of these. So easy to install and the app is simple to control and program the fan. I was very happy to discover that the speeds were also adjustable. Love love love it.
We love love love your review! Thank you for sharing this. Multistory townhouses are usually the toughest when it comes to airflow, so we’re thrilled to hear your space finally feels cool!
