The smart thermostat fashion is taking the world by the storm. Not only you can enjoy another smart home element, you can save substantial amounts on your energy bills. The variety of such thermostats on the market is becoming more and more impressive each year. Nest and Ecobee seemed to be the only leaders, but Honeywell is catching up fast.

If you are looking for a fair-budget model, you may be choosing between Nest E and Lyric T6. Let’s take a look at their comparison.

Thermostat Design

Nest E and Lyric T6 have completely different designs. Nest has a round shape while Lyric T6 is styled as a keyboard button. Both models are white. To say the truth, these thermostat controllers both look excellent and fit into any décor. In the rare case you don’t like the design, you can install the thermostat in a corner, where it’s virtually unnoticeable.

Nest E is much smaller than Lyric T6. However, on the big scale of things, they are both small and compact. Some reviewers say that Nest E has a more futuristic design.



Here is a major difference between the two, which often keeps people from buying the Lyric T6 model.  While Nest E can be installed on your own if you have all the necessary wires already protruding from the wall, Lyric T6 needs professional attention for wiring UWP mounting system. In both cases, installation is rather quick, especially if you take full advantage of the detailed instructions that come in the box.

Professional installation may require more time (waiting for the technician to come) and extra expenses.

Important: C-wire is recommended for Nest E installation. However, the manufacturer claims that this thermostat can work without a C-wire.

Nest E vs Lyric T6: Similarities

Lyric T6 can remind you when your HVAC system is due for maintenance. These features are especially useful for people, who are often away from home.

Temperature Scheduling

Nest is a learning thermostat, which bases the cooling and heating schedule on your activity. You can also use a manual scheduling option to set up the temperatures depending on time or day of the week. Lyric T6 is not a learning thermostat. However, it has the same manual scheduling options for 5-1-1,5-2.

Some users report that Nest E’s learning feature is not always ideal and it’s better to take advantage of the manual scheduling.

Smart Integration

Both thermostats work with a variety of programs, including Google Assistant, Amazon Alexa, Apple HomeHit, and IFTTT. You don’t need to adjust your habits and switch to other devices in order to integrate the thermostat into your lifestyle.

Nest E vs Lyric T6: Important Differences

Geofencing vs Nest Home/Away Assist

Both thermostats have home/away function to turn on or off the HVAC when you are home or away from home.Lyric T6 uses geofencing which is most common way like other products,but Nest E uses built-in activity sensor – the same things the Nest Learning Thermostat has been using . They adjust the temperatures accordingly. When you are close to home, the thermostat ups or decreases the temperature to make it comfortable by the time you open the door. However, some users complain the Lyric T6 geofencing option doesn’t always show the best performance.

Wi-Fi Connection

Both products are easy to connect to mobile device via WiFi,but Lyric T6 only works with 802.11 b/g/n@2.4GHz home wireless router, and Nest E can also uses 802.11 b/g/n@2.4GHz and 802.15.4 @2.4GHz and 802.11a/n@5GHz.

Nest E offers more Wi-Fi options than its counterpart. However, 2.4 GHz range is the most common option for homeowners all over the world, so the absence of 5GHz for Lyric T6 is rarely a problem.,

Indoor and Outdoor Sensors

Today, Nest offers Nest temperature sensors for its Nest E unit. You can invest in those additional wireless sensors, which can monitor the temperatures in several areas. Then the thermostat can keep the temperatures comfortable where you are . This is important for houses, which have rooms with drastically different temperatures.

Lyric T6 Pro also has an option for sensors,but they are hardwire sensors. Its S/S terminal supports indoor(Part#C7189U1005) and outdoor wired sensors(Part#C7089U1006). These sensors are also optional and require additional expenses. Nest doesn’t have an option of outdoor sensors.

Energy Reports


One of the most important features offered by the smart thermostat is energy saving. Energy reports allow the homeowners to make decisions about better energy use. For Lyric T6, Honeywell provides monthly reports if the user signs up for the program. Meanwhile, Nest E offers its energy history report within Nest E,app and Nest web portal.


The price difference between these two thermostats is about $30 – $40. Nest E is a more expensive option. However, you have to consider installation expenses for Lyric T6, which can shorten the price gap between the two units.

You can also take advantage of the rebates provided by some utility companies. You may save on the purchase or get cashback after the installation.
