The essence of smart home network conflicts lies in the competition for resources in the 2.4GHz frequency band. Establishing a system of “complementary protocol characteristics + three-dimensional network planning” can achieve stable operation. When Zigbee (2.4GHz) and WiFi (2.4/5GHz) interfere at the same frequency, the data transmission error rate increases by 40%, necessitating a comprehensive … Read more
· Abstract · Smart homes bring convenience to daily life but also pose privacy and security risks. Smart sensors continuously collect information about the surrounding environment and transmit data remotely via wireless communication. To protect user privacy, a dual-modal fusion method for ZigBee device identification is proposed. First, ZigBee traffic data from smart home devices … Read more

In the era of the Internet of Things, communication between smart devices has become particularly important. Whether it is smart homes, industrial automation, or remote monitoring, efficient and stable data transmission between devices is key. Serial transparent transmission technology acts like an “invisible bridge,” silently supporting communication between these devices. Today, we will discuss serial … Read more
In 2019, I purchased the “Xiaomi Mijia Smart Home Kit,” which I truly started using in early 2020. At one point, I noticed on the app: “Door Magnet Sensor” — “Battery” — “Battery Low”; so I quickly bought a battery to replace it, but the app still indicated low battery; however, in the “Device Consumables” … Read more
