When things stop working, you’re on your own. I’m currently locked out of my own home system and haven’t gotten a response from customer service in 5 days. I’m throwing my device in the trash. ### 1/5 — An app that doesn’t work *2026-05-27, version 2.0.99* It is absolutely a useless app. It never worked and it apparently won’t ### 1/5 — Long suffering customers of this hideous app *2026-01-03, version 2.0.98* I despise trying to make this investment live up to minimal expectations. For those on old oil boiler systems there aren’t many options. ### 1/5 — Worst app ever *2025-12-21, version 2.0.98* Never seen an app that just doesn’t work. ### 1/5 — Junk *2025-12-12, version 2.0.98* Poor functionality. And similar to reviews below, the app no longer works correctly to reprogram a thermostat. So it’s stuck in manual mode. ### 5/5 — It work until ver 2.0.98 *2025-12-01, version 2.0.98* Installed mothers house in September 2021 she lives 4hr away could see temps and run times and know she was ok summers and winters Now I get failed to preform your request please try again ok Went to her home stat connected to her internet along with my phone on router setup Did reset of phone router and stat and software Failed to preform your request try again ### 1/5 — Unable to connect to WiFi or this App on my iPhone *2025-12-01, version 2.0.98* Worked for 3 years and for about a week now you are unable to even open the App (Alert:Failed to perform your request, please try again later), so I am unable yo connect to Alexa anymore because you can't get WiFi to even load on the thermostat. Just got off the phone with "Mike" in technical Support and he said it's a known issue on iPhones, and they are gathering information for the developers to "maybe" fix this "KNOWN" issue!! In the meantime, I can't control my thermostat at all, period. So, are we supposed to go buy a new one or wait (who knows how long or if they are even going to fix it)...FRUSTRATING TO SAY THE LEAST!!!!!!!! $150.00 Thermostat down the toilet!!!!! Ugh!!!!!!! ### 1/5 — Does not work *2025-11-25, version 2.0.98* Had to make a four hour trip to manually turn off my Lux Geo thermostat since the LUX app I have on my iPhone doesn’t work. Tried several different ways to get it to work, but failed…..this a just a failed product. I’m very disappointed and frustrated. Make sure you look elsewhere for a smart thermostat. Whatever you do, don’t purchase this product. ### 1/5 — Does not work *2025-11-22* Had to make a trip to manually turn off the Lux thermostat while the app I have on my iPhone doesn’t work. Tried several different ways to get it to work, but failed…..just like the product. I’m very disappointed and frustrated. Make sure you look elsewhere for a smart thermostat. Whatever you, don’t purchase this product. ### 3/5 — They Finally Fixed the App *2025-11-16, version 2.0.98* 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. ## Frequently asked questions about Lux Products ### What does the Lux app do? The Lux app allows you to remotely control your compatible Lux smart thermostat.
