Lux Kono Smart Thermostat Review

When we reviewed the Lux Geo Smart Thermostat last year, we gave it high marks for style, ease of installation, and smart scheduling features, but we wished it would work with other smart home devices. The Lux Kono Smart Thermostat ($149.99) represents the company’s next generation of smart thermostats, and like its predecessor, it’s sleek, easy to install, and offers the same convenient scheduling options. It also offers support for Alexa, Google Assistant, and Siri voice commands, and uses geotagging to adjust your home’s temperature based on your location. However, it doesn’t work with other smart home devices and doesn’t offer room remote sensing like the Editors’ Choice smart thermostat, the expensive Ecobee4.

Design and Features

Lux Kono Smart Thermostat works with most conventional two-stage / single-stage refrigeration systems as well as most heat pump systems with two-stage heat / single-stage cooling and auxiliary heating.

At 4.5 x 4.5 x 1.0 inches (HWD), the Lux Kono Smart Thermostat is roughly the same size and shape as the Ecobee 4. It uses a removable headboard and can be ordered in one of five shades, including midnight black, navy blue, hibiscus red, sea green, and true white, or you can order the headboard to paint yourself. If you decide to repaint the room, don’t worry: You can order additional facades for $10 (paintable headboards are $15).

The front of the Lux Kono Smart Thermostat features a brushed aluminum knob and a 1.7″ x 1.7″ white backlit LED to raise and lower the temperature, navigate menus, and select settings. Heat refers to heating/cooling. mode and fan mode. Press the knob to activate the menu system with the system mode buttons (turn the system on and off and set it to heating, cooling or automatic) and fan mode (on, off, automatic, IAQ). IAQ mode allows the fan to run periodically to circulate fresh air even if the system is not operating in heating or cooling mode. The calendar button allows you to follow the heating/cooling schedule (created in the app) or maintain a constant temperature for a specified period of time.

Lux Kono Smart Thermostat uses the same Android and iOS mobile apps as Lux Jio and can also be controlled via the web console. The home screen displays the name of your home and all installed thermostats. It also has a Set Away button that puts the thermostat into Away mode to help conserve energy, and a Radius button that lets you set a geofencing perimeter that automatically puts the Kono into Away mode when you leave. It puts it in Home mode when you return. Tapping on the thermostat’s name takes you to the main screen, which shows the current room temperature and target temperature. It also displays the outside temperature, but it lacks the detailed extended weather forecast you get with the Ecobee 4 and Honeywell Lyric thermostat.

Near the bottom of the screen are the Mode, Fan, and Hold buttons (which cancel the schedule to maintain your current temperature). Below it are four more buttons. Schedule allows you to set a heating and cooling schedule based on your usual weekly activities. For example, you can create a fixed schedule for all days of the week, or create a schedule with different temperatures and times just for each day or weekend. The app provides a handy guide to your heating preferences efficiency that shows you how much you’d spend as a percentage if you set the temperature to 74 degrees versus 68 degrees. Once you choose the preference, you can use the sliders to set the times the thermostat will turn on and off depending on who will be in the house.

The Deals button tells you about any discount programs in your area and helps you sign up. The Runtime button opens a screen that shows graphs with hourly heating and cooling temperatures, but it doesn’t provide the accuracy you get with Ecobee 4, giving you heating/cooling periods. It displays the outside temperature and average humidity during. The Settings button allows you to set the temperature outside, reset the schedule, and rename the thermostat.

Lux Kono Smart Thermostat supports Alexa, Google Assistant, and Siri voice commands, but actions are limited to raising and lowering the set temperature. You cannot turn the thermostat on and off or dial the current room temperature. Missing support for IFTTT applets that allow you to set up small programs to make the thermostat interact with other IFTTT-enabled devices such as fans, lights, smart switches, and motion sensors. However, you can use Apple’s HomeKit platform to change temperature settings with Scenes to raise or lower the temperature and change the system mode.

Installation and Performance

Installing the Lux Kono Smart Thermostat is relatively easy, but if you are not familiar or comfortable with low voltage electrical wiring, you may want to have it done by a professional. It uses a C wire (regular), but like the Ecobee 4, it comes with an adapter for systems without a C wire.

Before installing the Lux Kono Smart Thermostat, I Installed the mobile app and took a picture of my current wires before removing my old thermostat. Since I have a dual zone primary heating system, I connected my wires to the common terminals, W1 and R on the mounting plate and put the thermostat in place. It turned on immediately and invited me to select my system type (F for furnace or boiler, HP for heat pump) and fan type (gas, electric, boiler). Next, the screen asked me to select the operating system (Android or iOS) and open the mobile app to search for the device. My Lux Kono Smart Thermostat was detected instantly and it took a few seconds to join my Wi-Fi. I removed the cover and checked the HomeKit code when prompted, and waited a few more seconds for the thermostat to come online. I gave it a name and the setup was complete.

Lux Kono Smart Thermostat did great in my tests. I responded quickly to temperature changes using the app, web console, and manual dialing, and followed my schedule to a tee. I also followed my Alexa voice commands to raise and lower the set temperature, always switching between Away and Home modes whenever I left my set parameter and came home.


Lux Kono Smart Thermostat is an affordable smart thermostat that you can customize to match your home d├ęcor. It’s relatively easy to install and offers plenty of smart features, including Alexa, Google Assistant, Siri voice control, geofencing, and smart scheduling based on your family’s lifestyle. But although it does provide runtime usage reports, it lacks some details that can affect heating and cooling behavior such as outdoor weather conditions and humidity levels. And while you can control Kono with HomeKitSense, you can’t run it with other smart devices using IFTTT applets. However, the Kono performed flawlessly in our tests, and the mobile app and web console make it easy to create schedules, set up the geofence perimeter, and manually set target temperatures.

If you have an extra $100 to spend, our Editors’ Choice, Ecobee 4, is one of the most feature-rich smart thermostats out there. It has Alexa voice technology built in and can do everything an Amazon Echo can do, using remote sensors to maintain a constant temperature in your home, and third-party devices via IFTTT. It works with a lot. If that’s outside your price range, the Nest Thermostat E is another solid option with extensive third-party support.
