Smartmi Link 4+

Be warned, if you use this app to disable the LED screen on the smartmi p1 air filter, the screen becomes locked to either 100% brightness or off. It will no longer automatically adjust to the brightness of the room. To restore functionality, a factory reset of the air filter is needed. The app also suffers from some fairly poor UI design. However, the app is capable of turning on and off the really quite nice air filter remotely, so it earns 2 out of 5 instead of 1 out of 5

I’ve been using the Smartmi App for a few days now and the app works really well! Great UI, simple, easy to follow, modern looking and actually functional. I have no complaints at all! - not sure why there are so many negative reviews. Though, I would like to suggest a few things. Some of the features need some explaining. I had to result to a search engine because I couldn’t figure out what a few features were. The PM 2.5 (then the number 000) should have a tappable (i) icon next to it to inform the user what this means exactly and with a chart showing the number ranges of good to bad air quality. There is no explanation on what this means. Another would be when you tap Air Quality on the home screen it takes you to a line chart of info with no explanation of what the data implies too. Another would be for the PM2.5 Density air quality sensor In the Apple HomeKit App. I can tell it says “excellent”, but when it states (5μg/m3) how is an average user supposed to know what this means without leaving the app and researching it. Data with no explanation or resources is deemed pointless. I’m fairly new to the air purification world but those are just a few of my suggestions for the app. As for the product it works perfectly! Highly-highly recommend. I’m using the Smartmi app 2.9.0, Apple HomeKit with an iPhone 14 Pro iOS 16.1

There was a firmware version over a year ago that did bad things but I’ve had nothing but perfect firmware for at least a year now. The Airpurifier P1 is awesome, small, and robust. Unlike many others it’s made of quality material with aluminum and leather. Mine have been quite quiet, definitely quieter than the humidifiers I also run. I don’t really use much of the smart items for these, I mostly just let them change speed as needed or turn it up if someone’s sick and I’d like more purification.

The new app update cleans up the interface quite nicely. It’s still a little unintuitive at times but really no more so than Apple’s own apps.
