Even though Home Assistant's official integration with Xiaomi's devices might not be as extensive as the unofficial offerings, it is always my preferred option. Official integrations won't be left to die unnoticed, and you will receive a warning whenever any functionality is removed. Owners of Xiaomi's latest additions to their line of Smart Air Purifiers can finally breathe a (clean) sigh of relief, as the Xiaomi Smart Purifier 4 Lite is added to the list of supported devices of the Xiaomi Miio integration.
The Xiaomi Smart Purifier 4 Lite differs from its more expensive sibling in its slightly lower Clean Air Delivery Rate and lack of negative ion generator. It also ditches the OLED screen for a slightly cheaper looking seven-segment display. What it lacks in features, it makes up in pricing, as it is listed anywhere between 15% and 20% cheaper.
It isn't just the Lite model that benefited from Home Assistant Core Version 2022.11 though, as it is finally possible to adjust the standard model's screen brightness. This new ability will benefit those that want to be able to read the air quality, temperature, and humidity during the day, but desire absolute darkness while sleeping.
While the fourth generation of Xiaomi's Smart Air Purifiers isn't available on their official Amazon store yet, they can be purchased on AliExpress. Alternatively, the previous generation, which also nicely integrate with Home Assistant, are available.
