This only works if you have a compatible Echo device, and it only works when using that Echo device. You also have to use that exact command. Variations of this command will fail, or Alexa will misinterpret. If any other Echo device picks up your question, even in the same room as the compatible Echo, it won’t be able to give you the temperature. To find out the temperature from your compatible Echo from other Echo devices or the Alexa app, you need to assign it to a device group. Once you’ve assigned the sensor to a device group, ask any of your Echo devices, or even the Alexa app, about that group’s temperature. For example, if your compatible Echo is in your living room, you would ask, “Alexa, what’s the temperature of the living room group?” or “Alexa, what’s the temperature in the living room?”
Alexa-Compatible Thermostats and Standalone Sensors
While only a few Echo devices include built-in temperature sensors, there are other ways to add Alexa-enabled temperature sensors to your home. The two most common options are Alexa-enabled thermostats and standalone temperature sensors. If you install an Alexa-enabled smart thermostat, you can use Alexa to find out the current temperature at the thermostat in addition to raising or lowering the A/C or heating temperature. To find out the temperature from one of these thermostats, you ask, “Alexa, what’s the temperature inside?” You can also ask, “Alexa, what’s the temperature of the thermostat?” or “Alexa, what is the thermostat set to?” Standalone temperature sensors work in much the same way as the temperature sensor found on compatible Echo devices. Once you’ve connected one of these sensors to Alexa, either via Wi-Fi or a wireless hub, you can assign it to a device group and then ask, “Alexa, what’s the temperature of (device group)?”
