A comprehensive comparison between the ecobee3 and ecobee3 lite product Features
1. Power Source
Power is the lifeblood of any electronic system. The ecobee3 and the ecobee3 lite both use power that is supplied to them through the C-Wire. This is used to power both the display on the thermostat unit as well as its Wi-Fi. This makes the ecobee3 and the ecobee3 lite different from other smart thermostats that use built-in batteries. This give you the advantage that you will not have to deal with checking the amount of juice left in the battery, and you do not have to worry about replacing the batteries. All you need to do is install the unit and completely forget about it.
If you do not have a C-Wire then that is not a problem at all. The devices are quite versatile and come with a power extender kit included. This allows you to connect it to the furnace control board and draw power for your thermostat from there. You do need to note that the power extender kit needs a professional to install it otherwise you could end up damaging your HVAC control board, the thermostat and you can even end up harming yourself in the process.
2. Room sensors
The ecobee3 lite does not come with room sensors. It is compatible with room sensors, but you will have to purchase them separately. The ecobee3 comes with a room sensor. This sensor is a wireless sensor that you can place in a room that you most frequently use. This sensor will them detect motion in the room and will be able to identify whether or not the room is occupied. The sensor is also able to distinguish between a human being and a pet. This allows for cost savings as the thermostat will not heat up, or cool rooms that are not occupied. Each thermostat supports up to 32 sensors that is more than enough for a medium-size house. As explained above, the sensors are wireless, and they are powered by 3 Volt CR-2032 batteries. Due to the efficiency of the sensors, these batteries last for up to 4 years. In addition, the room sensors do not need an application to set them up and they link up directly to the main unit.
The room sensor, while it’s a great feature may be unnecessary to those who do not have a big house. If you have a small apartment or a small home, the sensor may be quite unnecessary as the thermostat will be able to do quite a good job on its own.
3. Follow me and Home/Away mode
Both the ecobee3 lite and the ecobee3 come with the follow me mode as well as the home and away mode. These modes are designed to utilize the sensors that come in the thermostat, as well as the room sensors to detect whether you are at home. If you are at home, they detect which room you are in.
In the follow me mode, the room sensors detect the room, or location inside the house. This allows for them to heat or cool those areas to ensure maximum comfort. As you pass the sensors, the system automatically determines where you are and updates the HVAC system accordingly. This allows for the system to only keep the room that you are currently in at the optimal temperature, and thus save energy that would have been wasted heating or cooling an empty room.
Home/Away mode uses your location. This feature uses sensors as well as Geofencing. Sensors detect whether a person is present at home or not. If a person is detected at home, the home setting immediately overrides the away setting. In Geofencing, the thermostat tracks your phone’s location. It is only available with the ecobee3 thermostat as the ecobee3 lite thermostat does not support this feature. This feature allows the ecobee3 thermostat to track the location of your phone, and when it detects that you are approaching your home, it automatically changes the away setting to the home setting and heats or cools your home to your favourite temperature.
4. Voice Controls
Both the ecobee3 and the ecobee3 lite are compatible with home automation systems such as Apple HomeKit, Amazon Alexa, and Google Home. This allows you to easily control your thermostat using your voice. Using these systems is very simple and quite fast. This means that if you are a fan of apple products, you will enjoy using these products as you will be able to control them using your iPad, iPhone or even your iWatch.
5. Ventilation, Dehumidifier and Humidifier controls
This is the feature that distinguishes the ecobee3 from the ecobee3 lite. The ecobee3 lite does not include the support for humidifiers, dehumidifiers and ventilators within the HVAC system. This means that if you have any of these systems or if you plan to include these features at a later stage, then the ecobee3 lite is not for you. If you do have these systems, then the ecobee3 lite may be a feasible option.
6. Smart Recovery
This is a feature that is available in both the ecobee3 and the ecobee3 lite. What this feature does is that it considers the current weather conditions and forecasts to determine the best time to heat or cool the house. With this feature enabled, there is absolutely no need to schedule the temperatures at all. The thermostat will do all of the hard work for you and will automatically adjust the temperature without your intervention. This means that it will activate features such as the AC or heaters only when you need them, thus, saving energy.
7. Mobile App
Both the ecobee3 and the ecobee3 lite come with a mobile application. This application is available on both the android and iOS platform. This application is quite easy to use and is designed with an interface that is quite similar to that present on the main thermostat. The response of the thermostat to the commands input depend on the strength of your Wi-Fi connection, meaning that if you have a good connection, you will find the experience to be fairly quick and seamless.
8. Data tracking
Users with both the ecobee3 and the ecobee3 lite have access to a web portal. On this portal, the users have access to a wide variety of features such as providing commands to the thermostat, as well as accessing the history of the thermostat. In the history, you get details such as the changes in temperature settings, the energy consumption as well as the implemented changes in temperature. This data is encrypted and is therefore safe from prying eyes. It is important to note that the thermostat will only start tracking data after a whole month of usage.
The process of installing the ecobee3 and the ecobee3 lite is quite easy and quick. Any DIY enthusiast will be able to install these devices with ease, provided that there is a C-Wire present. If there isn’t a C-Wire then there would be the need for a professional to install the device.
The process is quite simple due to the touchscreen interface that provides very easy to follow steps. It is so easy to set up this device that an average user will take around 15 minutes to finish the set up process. Once you have finished installing the thermostat, you need to create an account on the ecobee app. You can do that on your phone, or on the ecobee website (web portal). After this you can add HVAC devices to the thermostat’s system. Once you have completed this, you can easily control your thermostat using your tablet, phone or computer. You immediately get access to a wide host of features.
The ecobee3 and the ecobee3 lite have quite similar interfaces. They both have a 3.5 inch full-color LCD touch screen (dimensions are 320×480 pixels). When they are in the inactive state, they display big white numbers that indicate the weather conditions, current temperature, as well as the outdoor temperature. When the motion sensor detects a person, the display changes. The big white number remains, but to the right of the screen, little dots that form a vertical line will appear which you can use to adjust the temperature setting. When the main thermostat is active, you will be able to see different icons on the interface as well as various settings.
The ecobee3 is more expensive than the ecobee3 lite. This is because it comes with a host of features such as support of HVAC systems with humidifiers, dehumidifiers and ventilators. It also comes with a sensor in the package. Apart from these features, the systems are pretty much the same.
