What We Like Most About Keen Smart Vent:

Keen Smart Vent: Room By Room Temperature Control Approach

A single, smart vent or multiple vents are often needed to replace uneven airflow with correct air balance throughout the house. To begin with, users can start using vents in a couple of rooms. The Keen suggests using vents in 30 to 50% of the house.

The next important thing to decide is which room you should put into getting an effective solution. The smart way is to identify the room that needs fixing. The vent in rooms that have too much heating/cooling or often unused closes so that the airflow is redirected in other areas where it is needed. As a result, the temperature becomes stable in the house. Users can also simply install vents in a room having too much airflow. In that case, only that specific room needs the device to even the temperature.

The Keen Smart Vent needs a Smart Bridge to operate. It is suggested to use at least two smart bridges. The intention is to act as a bridge between the vents and Keen cloud. If you have 2, the first one will act as bridge and other as a wireless signal repeater. Certain obstacles can block radio signals from reaching your vent, and that is where the repeaters work. It promises uninterrupted connection and longevity of battery life.

One common question is, how many will you need? Well, it depends on the setup.  If the vents are far away for a double or triple floor in a building, might need 3 or 4 repeaters to hold the connection.

Another feature is Keen Zoning, this helps to move excess air from over-conditioning place to under-conditioning ones. The app allows users to customize schedules, select degrees of specific rooms, and other integrated devices.

The users can schedule times when the room will be empty or full; a time when the vents will be open or close can control the temperature physically.

Keen Smart Vent Review:Heat and Cooling System

The primary purpose of a Keen smart vent is to control the amount of airflow in a particular room and maintain a specific temperature to achieve a comfortable scenario. It will eliminate the problem of 'extremely hot or cold spots' in the house.

It is suggested to install smart vents in approximately half of the house.  Many houses have rooms that are either very hot, cold, or remain unused. Users have to close the vents partially according to their needs so that the airflow is reduced in the problem rooms and redirected to low airflow regions or vacant rooms to create a uniform temperature throughout the house.

However, users can also use vents in the problem room only (too hot/too cold). The vents will help to adjust the temperature to a moderate or your desired level. But it will not redirect the air to move to less-airflow regions.

Keen smart vent is made of plastic faceplate, which is easily replaceable. It is wireless and needs 4 AA batteries. It requires a smart bridge and temperature sensor to work on the circulation of air. Keen has another product that provides broad coverage of the house, that is, Ecovent.

Keen Home Smart Bridge:

The Keen official website recommends the use of one Smart Bridge for every 8 Vents. Also, they suggest using at least one Bridge on each floor. While the first bridge connected to the vent acts as a Hub, other additional Bridges will serve as a wireless repeater. Repeaters are needed so that the signal remains strong throughout the house.

Keen Home Temperature sensor:

The vent needs a smart bridge to connect to the Wi-Fi via low power Zigbee network. Another new addition is the temperature sensor. This allows the user to set an exact temperature for each room. The vent with a temperature sensor will act as a virtual thermostat, and the app will enable users to set a temperature limit. The vent will close before the temperature exceeds the limit.

Keen Home App:

The keen home app is user-friendly and understandable in use. The app helps in the connection between vents and other thermostats and creates zones in the house. The smart zoning helps to regulate temperature so that, for example, the baby nursery room doesn’t become too cold. This saves energy.

Flair Smart Vent Review: How Does Flair Smart Vent Work

The purpose of a flair vent is to ensure there are no cold or hot spots in your house. So that you don't shiver at night, and your baby doesn't sweat due to a temperature difference. This vent comes with a Flair Puck. With Puck motion sensors, it can determine whether someone is around so that it can start working.

The Puck helps to set a specific temperature, multi-zone, and works as a remote control. It supports more than 250 brands of mini splits, ACs (Mitsubishi, Fujitsu, LG, Panasonic, Daikin, Sanyo, Hitachi, etc.).


The diagram above shows what users should do based on their room issues. The room that has less air in it (cold in summer, hot in winter) should have a puck and vent in it. The room with overflowing air (too hot in summer/too cold in winter) should have a puck in that room and another puck and vent in another room so that the vent can realize whether to open or close vents and divert airflow in other rooms.

Also, if users wish to get a full house effect, then they need to have a vent and Puck in each room so that uniform airflow is maintained throughout the home. Here each room can have an independent temperature depending on the user's choice like you can set the baby nursery a bit warmer than the master bed.
