Lux smart thermostats are designed to be reliable, aesthetically pleasing, easy to operate, economical, and customizable as per your needs. The new Lux app exemplifies this design philosophy and helps you get the most value out of your Lux smart thermostat. • You can change the temperature using your phone no matter where you are • The informative dashboard shows you important details, including weather highlights powered by AccuWeather, without being overwhelming • Home and Away Aware™ saves energy when you are away and delivers comfort when you are home • Alerts inform you when the temperature in your house becomes too hot or too cold, or when it’s time to change your filter • Setting up and managing schedules is a breeze with the intuitive scheduling interface • Runtime statistics show you how much your heating/cooling system has been running With the new Lux app, you are truly in control! NOTE: The Lux app is compatible with KONO Smart, GEO, GEOX, and CS1 thermostats from Lux Products Corporation.

Planned obsolescence is bad
02/14/2024

pebcak_err
I have a Lux Geo that won’t connect to Wi-Fi for longer than 30 seconds. Apparently this is intentional on JCI’s (owner of Lux) part, as the firmware must be able to talk to their App or the device will automatically disconnect from Wi-Fi and refuse to stay connected… and support confirmed that thermostats not already on newer firmware have NO way to update, not even manually via USB, turning them into basic standalone thermostats with NONE of the smart features. Due to this, I would not recommend this app, any of their devices, or any of their other brands to anyone, as you have no way of knowing, even buying new, if it is old stock on old firmware that cannot be updated, so lacks important advertised features. If the App Store would allow me to upload screenshots, I would include my emails with support in this review. But what all of this tells me is that this is the reason so many users are having issues getting their thermostats to connect and talk to the app. JCI intentionally broke their functionality.

Woke up at 3am because it was 80 degrees in the home in a sweat. Even though I set the thermostat to cool 72. Figure maybe I should connect it to my WiFi. So downloaded the app and proceeded attempting to connect it. Here 3 hours late after some how the a/c turn back on around 5am. The App doesn’t connect at all. Is now 7am n I give up after reading reviews. Don’t waste your time and change thermostats ASAP if possible. 0 to negative 5 Stars. Waste of time.

They Finally Fixed the App

Review Update Nov 2025Version 2.0.98 actually works.Congrats Lux Team! You have FINALLY restored the functionality of my thermostat to the state of operation it offering in 2018. (Still no web portal but at least the app functions as intended.) IDK how long it has been fixed. I have not bothered with the app for over 2 years.3 Stars for meeting baseline expectations - 4 years later.And I hope I don't jinx myself with this review ================•Prior Review from about 2022 This app is totally broken. I was so excited 2 years ago when I set up 3 zones in my house using Lux, everything worked great. But the recent update has completely broken the functionality and made this a totally frustrating and disappointing component of my life. I will never purchase a LUX product again. They have shown a complete disregard for their customers with this app update. No QA whatsoever. They simply pushed a broken app out to the world. They keep promising updates (via v2.0.63) but good luck getting it. You only get the still broken and buggy 2.0.13. Good Bye Lux.

A long time coming

It took them way too long to address serious issues, and now there appear to be new ones. You would pause the schedule back in the day for 2 hours, sometimes it’d work, sometimes it wouldn’t, sometimes it’d pause it indefinitely, even though you set it for a short periods of time.Now it appears like it’s working correctly. Except sometimes you set a temp, and it’ll keep cooling well past your setting and it just keeps going. I don’t even trust it’s statistics anymore. Hopefully now that they’ve addressed old issues, that shows they’ll keep it up
