Amazon Alexa didn't control my Sensi thermostat as expected

When using Amazon Alexa to control your Sensi Thermostat, you may encounter a situation where Alexa does not perform the expected or desired action. There are several reasons why this may occur.

  • Your voiced command included contradictory operations
  • Amazon Alexa misheard your request

Contradictory Commands

When issuing commands to Alexa, ensure that your statements do not include contradictions. Alexa may not respond as expected if you request multiple differing operations (“lower and set temperature”) in the same statement.

If the name of your Sensi thermostat includes words like “lower,” “set,” or “raise,” Alexa may misinterpret the name of your device as your desired action for that device. To avoid this issue, rename your thermostat by using the Sensi app and then ask Amazon Alexa to discover your devices again.

Amazon Alexa misheard your request

If Alexa is having trouble understanding the name of your Sensi thermostat, try using the Voice Training feature in the Alexa app to train the Echo device to your way of speech. If you are still having trouble, you may want to rename your thermostat to a less complex name in your Sensi app and then ask Alexa to discover your devices again.

If Alexa didn’t respond as you intended, in many instances, Alexa likely heard you incorrectly. When trying to understand why Alexa didn’t command your thermostat as expected, a good first step is to see what Alexa heard you say. To do this, in the Amazon Alexa app, select Settings on the main menu. Then select History–View requests to Alexa. This will bring up a screen where you will be able to see what Alexa heard you say. If what was heard is incorrect, Alexa will not carry out your demand.

Thermostat Naming Note: When naming your Sensi thermostat, avoid using numbers (i.e., 1, 2, 3) in your thermostat name. If you must use a number in the name of your thermostat, Amazon recommends to spell it out instead-enter “one” as opposed to “1”, and so on. It is also recommended that you avoid acronyms (i.e. XYX).

  • Recommended: First floor thermostat
  • Recommended: Floor One Thermostat
  • Not recommended: Thermostat 1
  • Not recommended: Thermostat 1482
  • Not recommended: Thermostat RCB

If you want to change the name of your thermostat, you will need to do this in your Sensi app.

If you feel your thermostat name is simple and fits the above parameters, or Alexa has understood you in the past but now is not, you could be experiencing a connectivity issue. Connectivity troubleshooting may need to happen with either your Amazon Echo or Sensi thermostat.
