PROS / The LUX/GEO has geofencing.
CONS / It has a dated interface and cheap construction.
VERDICT / What the GEO lacks in panache it partially makes up for in overall performance and a generous warranty. It can regulate your home’s temperature and help you save money on utility bills.
The LUX/GEO is a comparatively affordable programmable thermostat that is easy to install and use. It also has geofencing, which is an uncommon feature, especially for a thermostat at this price point. This means the thermostat can detect when you are within a certain radius of your home and adjusts the temperature before you arrive.
You can program the geofencing radius using the app, which also lets you check the status of your thermostat at any time from your smartphone. If you leave the house for a few days, you don't have to worry about programming your thermostat before you leave, since the geofencing feature automatically switches the thermostat to Away mode when you leave and back to Home mode when you return.
While it’s more affordable than many of the products in our thermostat review, the cheap construction and dated interface are noticeably inferior. The whole look and design feels dated, with its old-fashioned block-letter interface and oversize retro dial.
This smart thermostat was relatively easy to install and worked well once we had it up and running. It requires the Common C wire, or if your system doesn't include a C wire, the two AAA batteries included in the package. It took longer than average to install the thermostat and connect it to the network, but once it was up and running, it did an effective job regulating temperature. To install the device, you simply mount the base plate on the wall and hook up the HVAC wires as the instructions direct. It can be mounted horizontally or vertically to best accommodate the space it occupies. Once it is hooked up, you can download the app and program your heating and cooling preferences. The app is straightforward and easy to use, and you can access it from anywhere on a smartphone or laptop. The app's interface is more modern than the thermostat’s physical interface but still lacks panache.
While it's not the most attractive thermostat, it performs well overall and can help you streamline temperature control in your home. The thermostat doesn’t integrate with many smart home systems, but it does work with Amazon's Alexa service. This means you can adjust the temperature using simple voice commands. However, you can’t use the GEO to turn on lights or open the garage door as you approach home. For most people, this is a small inconvenience, but as smart technology becomes more integral to our lives, it could become an issue later on.
The LUX/GEO has impressive support options. If you have questions installing or using it, you can reach customer support via phone, email or live chat. It comes with a solid three-year warranty, which is on par with some of the warranties of the best thermostats in our lineup. This gives you more than enough time to notice manufacturer defects.
This Wi-Fi thermostat doesn’t have a durable or modern design, but it performs well. It has just enough smart technology to streamline the temperature control in your home. Geofencing, as well as Home and Away modes, allow it to automatically adjust the temperature when you leave and return home. If you go away for the weekend it adjusts automatically, and you can always check the status of the temperature from your smartphone. It also lets you know how much you're saving when you make an effort to turn down the temperature consistently. The generous three-year warranty should provide peace of mind. Overall, it's not a bad choice, but you don’t get quite as much bang for your buck as with other thermostats we reviewed.
