A low humidity level can cause dry & itchy skin, might make you susceptible to colds & infections, and can cause damages to your wood furniture and floors. You also don’t want the humidity to be too high, since it can encourage mold growth, muggy condition, and might even cause sleep discomfort.

This automation routine will help you to control the humidity at a reasonable price.

How Does It Work?

  • Install humidity sensors and humidifiers in each of the rooms that your family sleeps
  • Trigger: Have a look at the average humidity levels in each room to decide two of the possible options:
    • Switch on the humidifiers each day at a ceratain period of time. The automation will switch them off if the humidity levels are over a certain level
    • Switch on the humidifiers only if the humidity levels fall below a certain threshold
  • Condition: this automation should work only if you are at home
  • Action: turn the humidifier on and off depending on the trigger mode
  • Note: do not forget to fill humidifiers with water

ADVANCED

  • You can use a door sensor to make sure that you do not forget to fill the water in your humidifier

What Do You Need?

The main thing you need for this automation is a humidifier. There is a number of options, but Cool Mist Humidifier – Humidifier for Baby Bedroom, Super Quiet Mist Humidifier is our favorite due to value for money and versatility.

Shut off valve

A valve that will close and open water supply
  • leakSMART Water Leak Detection Kit ($357.64) is a more expensive option. It has all you need to set you up shut off valve. There are some negative comments on the hub but it works well in general.
  • Grohe 22503LN0 ($399.00) is even more expensive. For the additional price, you have flow sensors capable to detect the pipe bursts without the sensors and better overall build quality. At the same, it has fewer options for integrating with your smart hub.

This is a more complicated device than a motion sensor and can be used where multiple environmental factors need to be detected:
  • Z-wave: Our favourite z-wave sensor is Aeon 6 in 1 ($59.99) for its reliability and flexibility in use. It detects motion, humidity, temperature, light lux, UV, vibration sensor and has 2-year battery life
  • Zigbee: Samsung SmartThings Multipurpose Sensor ($16.99) give you open/close, vibration, orientation, angle (tilt), and temperature measures for multipurpose functionality

      Voice assistant:

      AI driven device that can respond to voice commands

      There is no right answer which Voice Assistant to choose, but we have the following recommendations:

      • The most comprehensive: Amazon Alexa ($99.99) has a lot to offer. Zigbee radio means potentially one hub less (although we still recommend getting a dedicated hub). It also has the biggest ecosystem to tap into (including Ring, Phillips Hue, TP-link)
      • The most intelligent: Google Home is using the brains behind the biggest search engine in the world to deliver the best answers for your questions. It is definitely more capable compared to Alexa
