SanJie WiFi Door Chime – Open Door Alerts for Home/Business, 500 ft Range, 20 Ringtones, 4 Sensors + Receiver

Smart, Flexible Door Alerts for Home and Work

The SanJie WiFi Door Chime provides proactive door and entry monitoring with simple setup and versatile alerts. Designed to work with 2.4GHz WiFi and popular Tuya/Smart Life platforms, it streams notifications to your phone when doors or windows are opened. While the official spec highlights a 500 ft range, practical indoor use typically achieves reliable connections up to about 100 ft between sensor and receiver, with performance varying by space and layout. This system is built to help you stay informed, without requiring you to monitor every moment in person.

Key benefits at a glance

• Remote push notifications to your phone when any paired sensor triggers, so you can respond from anywhere.
• 20 chimes to choose from with 5 adjustable volumes (0–110 dB) and LED indicators that reveal which door opened.
• Memory function preserves your preferred tune and volume after power cycles, reducing setup steps.
• Expandable up to 20 magnetic sensors and easy sharing, so family members or colleagues can receive alerts in real time.

How it works and what you’ll install

Install the receiver close to your router (within about 33 ft is recommended) and connect it to the Tuya/Smart Life app. Attach sensors to doors, windows, cabinets, or even appliances using the included adhesive. The system supports multiple locations indoors, with a practical sensor-to-receiver distance of up to 100 ft in typical environments. The device communicates over 2.4GHz WiFi, so ensure your network is compatible before setup.

Real-world use cases

• Business entrances: greet customers with a polite chime as they enter, helping staff respond promptly.
• Kids and elder safety: receive alerts if a door or cabinet is opened, enabling quick checks.
• Home security: stay informed about any door/window activity and respond as you see fit.
• Care and workplace environments: use in offices, apartments, nursing facilities, or classrooms for flexible monitoring.

Setup tips and considerations

The kit includes 4 sensors and 1 receiver. To get the most out of the system, connect to a stable 2.4GHz network, follow the app pairing steps for Tuya/Smart Life, and place sensors where they will be most effective (high-traffic doors, medication cabinets, etc.). Note that 5GHz WiFi is not supported and environmental factors may influence range. If you plan to share alerts, the app can notify other users without extra fees, while some notification methods may carry optional subscription costs.
