- Xiaomi Vima (Smart Lock Upgrade): Good, but what happens if key registration breaks for some reason? Current version (A6121) is also incompatible with new Xiaomi Mi hubs (v3). Might be later when stabilizes.

- Xiaobai Smart Cat's Eye M1 (дверной зрачок): Тоже монтируется с той стороны и привлекает ненужное внимание.
