Software ：

1. Supports web-based page debugging, device management, and control.

2. Supports iPhone®, iPad®, and Android™ device control applications

3. Enterprise-level network security configuration

4. On the host web page, you can easily configure one-click scenarios, scheduled policies, linked policies, inspection policies, and alarm policies through simple check-and-drag editing. Advanced features required on-site can also be easily implemented.

5. Supports space grouping, enabling flexible switching between separate control and unified control of multimedia devices across multiple meeting rooms.

6. The system can collect environmental parameters including temperature, humidity, CO2, PM2.5, and PM10 via LoRa wireless protocol.

7. Control various devices locally or remotely via tablet or mobile app.

8. Device operation logs, including system operation logs, device operation logs, and alarm logs.

9. Supports remote debugging for web pages

10. The "Yilian Control" APP features a four-in-one scenario mode: it automatically generates three UI interfaces for "Meeting Control", "Exhibition Hall Control", and "Smart Office". The "Custom Mode" allows users to tailor the interface, meeting personalized needs and brand consistency requirements while enabling seamless switching between the four scenarios.

Application scenarios: IoT data collection and control for devices in government and enterprise meeting rooms, exhibition halls, office buildings, smart homes, smart campuses, and other environments.
