The DMLink G530 is a versatile smart lock designed to replace traditional keys with a variety of modern access methods. You can unlock your door using a semiconductor fingerprint sensor, a personalized password, or the Tuya and Smart Life apps via Bluetooth connectivity, though two mechanical keys are included for manual backup. The system can store up to 30 unique fingerprints and 15 different passwords, making it easy to manage access for several family members or guests. Constructed from a combination of black aluminum alloy and acrylic, the lock features a compact design with a 70 mm cover diameter and a handle measuring 58 mm in length and 62 mm in height. It is compatible with doors that have a thickness between 35 and 50 mm. To keep the device running, it uses four AAA alkaline batteries, and the system will notify you with a low battery warning once the power reaches 4.8V. Because it is built to operate in temperatures ranging from -25°C to 65°C and humidity levels between 25% and 95%, this lock remains reliable in various environmental conditions.
