7. What are Smart thermostats?
They’re pretty complicated, said Amazon at its hardware event on Tuesday. With the Smart Thermostat, the company is now taking matters into its own hands. The device was created in cooperation with the household professionals from Honeywell and should be particularly easy to use.
8. Is Alexa Heats Intelligent?
Of course, that alone doesn’t make control any easier than turning the wheel on the heater. That’s why the device can do a little more. If Alexa has an idea (yes, you read that correctly) that you are not at home, the smart little helper will turn down the temperature.
The same works for you too if Alexa thinks you’ve gone to bed. Both should help to save energy – and thus also put less strain on the wallet. Just how this mechanism has not yet been mentioned. I assume, however, that the new sound recognition from Alexa will be used.
