Smart Thermostats 
The short version: The Lux Kono is a budget smart thermostat built around swappable colored faceplates and a rounded, ecobee-adjacent design. Independent reviews from outlets including Consumer Reports and TechHive, along with owner feedback on Home Depot’s listing, generally describe reliable Wi-Fi connectivity and an easy setup, with the main complaints centering on the app’s limited feature depth compared to ecobee or Nest and occasional connectivity hiccups. Note that most published third-party reviews of this model are several years old; the hardware and app have reportedly seen only incremental changes since.
Who It’s For
The Kono is built for forced-air homes (gas, electric furnace, or heat pump) where you want a smart thermostat that looks intentional on the wall without paying ecobee or Nest prices. It’s sold at Amazon, Home Depot, and Walmart, giving it more retail visibility than most brands in this price bracket.
It’s a good fit for buyers who want basic geofencing and scheduling with a design element (interchangeable faceplates in colors like midnight black, deep blue, and champagne gold) and don’t need room sensors, air-quality monitoring, or the deeper energy-report detail ecobee provides.
Design & Build
The Kono has a rounded-square housing with an oversized central knob for navigation and swappable faceplates that snap on and off in seconds — a genuinely distinctive feature reviewers have called out favorably, since most competitors in this price range don’t offer any physical customization. The display is a straightforward digital readout rather than a large touchscreen.
Setup & Compatibility
The Kono supports conventional furnaces, central air conditioning, and heat pumps. Reviewers who tested the installation process described it as straightforward, with the app guiding wire-terminal matching. As with most Wi-Fi thermostats in this category, a C-wire is generally required for full connectivity; check Lux’s compatibility checker for heat pump or multi-stage setups before buying.
App & Ecosystem
The Kono connects to a smartphone app for scheduling, remote temperature control, and geofencing (location-based automatic setback). Independent reviews describe the Wi-Fi connection as reliably stable, both from inside and outside the home network, though some owners on Home Depot’s listing note occasional connectivity issues and a learning curve for first-time smart-thermostat users.
It supports Amazon Alexa and Google Assistant. It does not have the third-party ecosystem depth of ecobee (no native Apple HomeKit) or the detailed energy-usage reporting ecobee and Nest provide — reviewers consistently describe the app as functional but lighter on features than the category leaders.
Faceplates: The Standout Feature
Unlike most budget smart thermostats, the Kono lets you change its physical appearance without buying a new unit — faceplates snap on magnetically in a range of colors. Reviewers have called it one of the better-looking thermostats in its price bracket for this reason. It’s a cosmetic feature, not a functional one, but it’s a genuine differentiator worth knowing about if aesthetics factor into your decision.

The Recommendation
Buy the Lux Kono if you want a smart thermostat that looks distinctive on the wall, need basic geofencing and scheduling, and don’t require ecobee-level app depth or HomeKit support.
Skip it if detailed energy reporting, HomeKit compatibility, or the most current app experience matters more to you than design — ecobee’s Enhanced or Honeywell’s T9 will serve those needs better.
Frequently Asked Questions
Does the Lux Kono require a C-wire?
In most setups, yes, for reliable continuous Wi-Fi. Check Lux’s compatibility guide for your specific system before buying.
Is the Lux Kono compatible with Apple HomeKit?
No. It supports Amazon Alexa and Google Assistant, but not Apple HomeKit.
Can you actually change the Kono’s faceplate yourself?
Yes — this is one of its defining features. Faceplates snap on and off without tools, in a range of colors sold separately or with certain bundles.
How does the Lux Kono compare to ecobee or Nest?
It’s less expensive and offers a more customizable physical design, but its app has less depth: no detailed energy reports, no room-sensor ecosystem, and no HomeKit support. It’s a reasonable budget alternative rather than a direct competitor to the flagship brands.
