Do I need additional sensors for each room I install Alea? Brad September 25, 2018 17:49 Updated No. Each Alea vent is self sufficient and incorporates all the sensors and wireless connectivity that’s needed.

(Does it monitor and adjust for ducts' air static pressure?) What is the boot depth size requirement to support Alea vents? Comments 0 comments Please sign in to leave a comment.
