Frequently Asked Questions
Q: Does the YRHAND F8 smart lock work without a WiFi connection?
A: Yes. The lock supports Bluetooth connectivity, so you can still unlock it via the TTlock or Tuya app over Bluetooth when WiFi is unavailable. The fingerprint, keypad, IC card, and mechanical key methods also work entirely offline — no internet required for those entry modes.
Q: What doors is the YRHAND F8 compatible with?
A: The F8 fits a wide range of door types including wood, aluminum, steel, brass, stainless steel, armored, composite, and anti-theft entry doors with a thickness between 35 mm and 120 mm. It uses the standard 6068 mortise, making installation straightforward on most existing door preparations.
Q: How long do the batteries last, and what happens when they run low?
A: Powered by 4 × AA alkaline batteries, the lock typically operates for several months under normal usage. When the battery level drops, the lock sends an in-app low-battery notification, and the keypad will also alert you so you can replace batteries before they are fully depleted. A micro-USB emergency power port is typically available on the exterior for jump-starting the lock in a pinch.
Q: Can I give temporary access to guests or service personnel?
A: Absolutely. Through the Tuya or TTlock app, you can generate time-limited temporary passcodes that expire automatically. This is ideal for Airbnb guests, housekeeping staff, or delivery personnel — no need to hand over a physical key or change your regular code.
Q: Is the YRHAND F8 smart lock weatherproof for outdoor use?
A: Yes. The F8 carries an IP66 waterproof rating, meaning it is fully protected against powerful jets of water and heavy dust ingress, making it well-suited for exterior front doors exposed to rain and outdoor elements.
