Back button obscured . No back button have to close app and re open. App does not show time from Controller , allow you to set time. Sunrise sunset options in timer would be nice. Should be able to ser controller time from The app ### 2/5 — U-Smart? *2022-12-05, version 1.4.3* Me not so smart for buying a Chinese thermostat. When we buy any sort of Chinese tech it comes with risks both in terms of security and long term support. This app really needs an update. I’m not holding my breath that we will ever see one. I’m going to install it on an old iPhone with an old OS as a dedicated thermostat control device. ### 5/5 — U-Smart App *2022-08-15, version 1.4.3* The apps great and works a great, the only thing I am having a problem with is changing the time on the app/controller. As soon as I change it to British summer time on the controller, it jumps back. Would be great if you could change the time on the app +/- 1 hour. ### 1/5 — Doesn’t work! *2022-07-21* Cant even connect to a device. Says wifi password must contain chinese! It’s my decision what characters my password consists of. F U! ### 2/5 — Not working *2021-10-29, version 1.4.3* I have just tried to look at the room temperature on the app but it’s saying that it is 18deg when the thermometer on the wall is saying it’s 23deg. Please fix the app! ## Frequently asked questions about U ### What is U-Smart-AI?
