Mos-S1 Tuya Wi-Fi Fingerprint Smart Handle Lock

The Mos-S1 is an affordable Tuya Wi-Fi handle lock for bedrooms, offices, store rooms, and apartment doors. It opens five ways: fingerprint, PIN, card, the Tuya app, or a mechanical key, and you can unlock remotely from your phone.

It locks automatically after a delay you set. An electronic reverse-locking mode lets you lock the door from inside so that it can only be opened from outside with a key, useful at night or for a room holding valuables.

It is designed to replace an existing handle set without new drilling, cabling, or carpentry, which keeps installation quick and tidy, and suits rented homes where you can't alter the door.

We confirm it fits your door and existing lock, install it, and set up the app and users.
