With increased compatibility between Smart Devices you can use items that you thought were not previously available to you. A good example of this is the Google Nest Learning Thermostat. Please not that this item requires professional installation.
In as little as a week the Nest Learning Thermostat will automatically adapt as your life changes. It learns from your patterns of us and soon you won’t need to remember to change the settings because it will do it for you. That doesn’t mean that it is inflexible to one off situations. You can control the temperature from your smart phone, echo or other Alexa compatible device.
Google suggest that its Learning Thermostat will help you save money as it will adjust the temperature to your needs. It will adjust itself to an Eco Temperature after you leave the house. You will also need a Nest Temperature Sensor to ensure a certain room is the exact temperature you would like it to be.
