Smart digital door lock Avatto ZSDL-A270-S-ALI-5572 ZigBee — silver finish

Avatto ZSDL-A270-S-ALI-5572 ZigBee smart digital lock in a silver finish combines biometric access, card and code entry, app control and a traditional mechanical key in a single unit designed for residential and light commercial doors 35–60 mm thick. The lock supports multiple opening methods, offers fast response time and is compatible with ZigBee-based smart home systems for centralized access management. It provides remote management via Tuya Smart / SmartLife apps on iOS and Android and is engineered for extended battery life and reliable operation in a wide range of environmental conditions.

Advantages

The lock integrates five opening methods—fingerprint, IC card, password, mobile app and mechanical key—enabling flexible access management and rapid unlocking (1–1.5 seconds). Low standby current and efficient power use allow operation on four AA alkaline batteries for approximately 10–12 months. IP55 ingress protection and an operating temperature range from -20°C to 50°C ensure dependable performance outdoors and in varied indoor environments. ZigBee connectivity enables seamless integration with compatible smart home hubs and automation scenes.

How to use

Install the Avatto lock on doors with 35–60 mm thickness following the manufacturer's mechanical and wiring instructions. Power the unit with four AA alkaline batteries and register the device in the Tuya Smart or SmartLife app on a compatible iOS or Android smartphone to enable remote control and user management. Enroll fingerprints and IC cards, set permanent or temporary passwords, and pair the lock with a ZigBee hub if you require integration into an existing automation system. Use the mechanical key for emergency access or during initial setup if needed.

Usage recommendations

To maximise reliability, replace batteries before low-battery warnings become frequent, and test biometric and card entries after installation to confirm consistent recognition. For outdoor or exposed installations, verify that door seals and mounting points are weatherproof to maintain the IP55 rating. When integrating with a ZigBee hub or Tuya ecosystem, keep device firmware and app software up to date to ensure compatibility and security.
