Diyu Smart pitches multi-protocol locks for hotels and commercial sites

Shenzhen Diyu Smart says hotels, dorms, apartments and campuses need different lock architectures depending on network coverage, battery life and credential turnover. The company is positioning its Bluetooth, WiFi, LoRaWAN, cellular and RFID products as a single hardware lineup for commercial access control.

Why it matters: - Commercial lock buyers have to match wireless protocol to the building’s workflow, not just the distance a lock can reach. - Hotels, dormitories, apartments and campuses each need different credential lifecycles, battery expectations and network setups. - The wrong protocol can raise maintenance work, strain networks and complicate guest or resident access.

What happened: - Shenzhen Diyu Smart Co., Ltd. outlined a multi-protocol smart door lock portfolio for hotels and other enterprise properties. - The lineup spans Bluetooth, WiFi, LoRaWAN, cellular, RFID, Zigbee and Z-Wave options. - The company framed its hardware around use cases including boutique hotels, serviced apartments, shared housing, universities, corporate campuses, remote facilities and resort properties.

The details: - Bluetooth Low Energy locks work as offline or semi-offline nodes that connect directly with smartphones or nearby gateway bridges. - Bluetooth locks can run well over a year on a typical battery set because radio transmission happens only during credential checks. - External plug-in gateways can add remote unlocking and audit log extraction to Bluetooth systems. - WiFi smart locks connect directly to existing access points and let administrators issue or revoke codes and monitor door status from central software. - WiFi locks draw more power than Bluetooth or LoRa alternatives and can add congestion in large installations. - LoRa locks use sub-gigahertz communication between distributed locks and centralized gateways. - A single sub-gigahertz gateway can cover hundreds of rooms across multiple floors. - Diyu says LoRa locks can run 18 to 24 months on standard alkaline batteries. - 4G smart locks use embedded LTE Cat.1 modems to connect directly to cloud property management systems. - The company positions 4G locks for cabins, remote utility sites and perimeter gates where local networking is impractical. - The L7/L10 series supports Bluetooth, WiFi and RF433 communication. - The L7/L10 series is compatible with Tuya, TTLock and HTlock ecosystems. - The series supports timber and metal doors and includes fingerprint, keypad PIN, RFID card and mechanical emergency key access. - The PC01 LoRaWAN smart lock pairs internal sub-gigahertz radios with 8-channel gateways and management software. - The V1 smart cylinder lock retrofits standard European profile mortise assemblies without door replacement. - The V1 is also compatible with Tuya and TTLock. - Zigbee and Z-Wave locks can trigger automated guestroom scenes such as lighting, climate control and occupancy profiles. - RFID and IC-card locks validate credentials locally from data written to the card by front-desk encoders. - Traditional key-card locks avoid network infrastructure overhead but require manual card encoding or physical door visits for lost keys and audit logs. - Smart hotel locks can combine RFID readers with wireless backhaul to preserve plastic keycards while adding remote monitoring and mobile check-in. - A unified hotel lock system can connect with reservation engines and kiosks to issue PINs, mobile keys or RFID cards for confirmed bookings. - Diyu says its Tuya and TTLock and HTlock architectures support RESTful APIs and webhooks for unlocking events and energy-management triggers. - The company says corporate deployments can link smart locks to HR directory services for automated provisioning and revocation. - In Saudi Arabia and the broader Gulf region, Diyu highlights high heat, concrete construction and RF attenuation as deployment issues. - In Southeast Asia, the company points to villas and open-air resort layouts where LoRaWAN locks and 4G Cat.1 gateways can be more practical than structured cabling. - Diyu says standard AA alkaline batteries are important in some markets so maintenance teams can source replacements locally.

Between the lines: - The pitch is less about a single lock and more about a deployment playbook for different property types. - The company is emphasizing interoperability with major access-control ecosystems to reduce friction for system integrators. - The strongest message is that operational design, not wireless range alone, should determine hardware selection.

What's next: - Diyu Smart is inviting system integrators and hotel operators to contact the company for hardware specifications and sample units. - The company is also directing buyers to its full lock catalog on the Diyu Smart website.

The bottom line: - Diyu Smart is betting that commercial buyers want one vendor that can cover short-range, long-range and cellular access control across hospitality and enterprise sites.
