Lux Products

Review Update Nov 2025 Version 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.

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.

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.
