What Is An Alexa Compatible Smart Thermostat?

Smart thermostats are similar to programmable thermostats; they have a scheduling feature that allows you to set different temperatures for different times of the day.

However, they come with additional features, including:

  • Sensors that determine whether or not your home is occupied; they can suspend heating or cooling until you or your other family members return.
  • They use Wi-Fi connectivity to give you access to the thermostat at all times, regardless of where you are.
  • A smartphone application and web portal work together with the smart thermostat. This means your HVAC system can work autonomously or via remote-control.

An Alex-compatible smart thermostat takes things one step further; any smart thermostat compatible with Alexa will work with all Alexa-enabled devices. These devices include Echo, Echo Dot, and Echo Show.

How To Install An Alexa-Enabled Smart Thermostat

An Alexa compatible smart thermostat requires the following to work:

  • The thermostat itself.
  • A WI-FI connection.
  • A heating or cooling system of sorts (HVAC system).
  • A C-wire, or a common wire. This runs from your low voltage heating system (24v) and acts as a return path for continuous power for your thermostat.
  • A smart thermostat app that is downloaded to your smartphone, mobile device or computer.
  • An Alexa comptabile device.

To learn how to put these all together, refer to the brief installation section in our previous smart thermostats article.


Alexa Installation & Pairing

  • Install your chosen Amazon Echo Device
  • Download and install the required phone app.
  • Install your smart thermostat and register/link it on your phone app.
  • Link your smart thermostat to your Amazon Alexa-enabled device. To do this, enable the relevant skill on the Alexa App by finding the skills section.
  • You can now search for the skill that you require and enable it.
  • After enabling your skill, enter your login information.
  • Finally, once you’ve gone through the setup process, the skill will prompt you to discover devices/devices that you may have already added.

How Do Alexa Compatible Smart Thermostats Work?

Hunches

Alexa Hunches is a feature that allows Alexa to carry out tasks for you (with your permission).

It does this by tracking your daily routine and habits. What’s more, it requests to carry out informed decisions.

Here’s a good example; turning off your Alexa-paired lounge lighting by saying,“Alexa, goodnight.” Should you ever forget to turn off your lights in that manner, Alexa will remind you, either by voice or mobile push notifications. Alexa will not interfere should you choose not to turn your lights off.

However, there is an automated setting that you can enable. This will allow Alexa to perform tasks that you may have forgotten about, such as setting the temperature of your household or locking your smart doors after leaving the house.

Linking Alexa-Enabled Devices

We’ve already mentioned how smart thermostats can link to Alexa-enabled devices, Amazon Echo, etc.

This is important for smart thermostats that lack an onboard speaker or microphone. Thankfully, most of the latest smart thermostats come with these features.

Alexa Commands

With an Alexa compatible smart thermostat, you can:

  • Raise and lower the temperature of your household.
  • Set Schedules
  • Check the status of your households temperature.
