Yes, you can connect this connected watch to a Redmi device, as it's compatible with Android.

Redmi devices run Android, and the Huawei Health app allows pairing with any Android phone, including Xiaomi/Redmi models.

For a watch with the same options (health tracking like sleep, heart rate, SpO2, stress, cycle; activities like running, cycling, fitness; calls, weather, etc.) and native compatibility with your Redmi, check out the Redmi Watch (like the Watch 5 or 6), which run on a proprietary system optimised for Xiaomi.
