Smart Features Breakdown
Routine Learning and Adaptation

The Honeywell Evohome features an intelligent heating system that learns from our daily patterns to optimize our home heating. The thermostat learns the heating times for each zone in the home and adjusts to environmental changes, like weather conditions, to maintain a comfortable temperature.
This system allows homeowners to efficiently manage comfort levels in up to 12 zones from a single location, potentially reducing energy consumption and lowering bills. Plus, the more you use the system, the better it meets our needs, delivering a personalized heating experience.
Smart Scheduling and Automation

Smart scheduling allows you to create a heating and cooling schedule based on your daily routine. With this feature, you can program your thermostat to automatically adjust the temperature settings based on the time and day of the week.
For example, if you typically leave for work at 8 AM and return home at 6 PM, you can set the thermostat to lower the temperature during the day when you’re not home and raise it back up in the evening when you return. You can also create different schedules for different days of the week so your home is always comfortable when needed.
In addition to scheduling, the Honeywell Evohome thermostat has automation features that allow you to set up triggers that activate specific actions. For example, you can set up a trigger that turns off the heating or cooling when a window is opened or turns on the heating or cooling when the temperature drops or rises above a certain threshold.
Geofencing

The Geofencing feature of the Honeywell Evohome thermostat uses your smartphone’s location to adjust the temperature automatically when you leave or return home. When you set up geofencing, the thermostat will use your phone’s GPS to determine when you are leaving or entering a predefined area around your home.
When you leave the area, the temperature will automatically be adjusted to save energy and reduce your cooling and heating bills. When you return, the thermostat will adjust the temperature to your preferred settings so your home is comfortable when you arrive.
The Geofencing feature also allows you to set up multiple users so that the thermostat can adjust the temperature based on everyone’s location in your household. For example, if you have a partner or family member who leaves and returns at different times than you, the thermostat will adjust the temperature accordingly.
Voice Assistant Integration

The Honeywell Evohome smart thermostat is compatible with Amazon Alexa. You can easily control the temperature in your home by using voice commands through a smart speaker or smartphone.
Say something like, “Hey, Alexa, set the living room temperature to 22 degrees”, or “Alexa, turn off the heating in the bedroom”.
By integrating voice assistants, you can also create routines to automate your smart heating systems, such as turning off the heating when you leave the house or arrive home.
Zones and Individual Temperature Settings

The Honeywell Evohome controller allows us to enjoy a tailored heating experience that provides room-by-room control. This smart thermostat is designed to handle multiple zones, allowing us to set different temperatures for each heating room in our home.
By dividing the house into separate heating zones, we can be more efficient about our energy use and maintain ideal temperatures on a room basis.
One of the best features of Honeywell Evohome is its ability to handle quick actions like “Day Off,” “Eco,” and “Away” modes, which adapt our entire central control unit system to match our daily routines.
Customisation
When it comes to managing the Evohome system, the app also offers the following options for a customized experience:
- Quick actions: Provides easy access to key settings like “Away mode” or “Eco mode.”
- Zones: Enables the creation of zones to group rooms and control them simultaneously.
- Notifications: Keeps us informed with alerts about important system events, such as low battery or extreme temperature warnings.
