Applicable scene
Applicable scene Suitable for large-scale networking in home scenarios, it can realize local mobile control, remote control and cloud connection, which requires network access nodes Suitable for individual products, needs the cloud For point-to-point connections between local mobile and devices It is suitable for small-scale local networking applications, and a gateway is required to connect to the cloud Local networking suitable for traditional Zigbee scenarios, requires a gateway to connect to the cloud
Underlying support metrics
Network topology Mesh network: decentralized design, each node role is equal, can achieve fault-free operation, any node added will automatically join the network, fast convergence and networking Point-to-Point single-hop network: used between routers and devices Point-to-Point single-hop network: cannot be expanded with distance Mesh network: It requires a variety of node forms, such as Relay node and Gateway node, and the network convergence and stability time is long Mesh network: It requires a variety of node forms, such as Relay node and gateway node, and the network convergence and stability time is long

Configuration and networking indicators
User experience The mobile phone Bluetooth can automatically discover the device, without relying on the Bluetooth connection: that is, scan and use, what you see is what you get, one-click scene saving, no need for professional installation and maintenance; up to 90 pairs per minute Complex user use and poor usability: APP download, wireless router SSID/PWD input, router connection and cloud connection; Long time connection of mobile phone's Bluetooth is required: the connection time is long and the experience is poor Nodes that require the phone's Bluetooth connection to the network: The connection time is longer and the experience is poor Mobile phone cannot be directly connected: You must connect to the gateway node through WIFI/LAN to control the devices in the network
Networking Building Level Large-scale networking : there is no central node mechanism in the whole network, so there is no limit on the number of hops for network extension, and the network scope can be expanded to the entire office building (5 floors) N/A N/A Small-scale networking: depending on intermediate nodes, with more hops between the gateway and edge nodes, the more stable connection decreases, so it does not have the ability of large-scale networking Small-scale networking: depending on intermediate nodes, with more hops between the gateway and edge nodes, the connection stability decreases, so it does not have the ability of large-scale networking
Certification and connection control indicators
Certification and security High security: supports the public and private key license mechanism of devices, dynamic key production mechanism, and two-way authentication between the two parties Low security: The key input of SSID/PWD in standard WIFI is easy to leak Low security: no authentication capability, or only single password level authentication Low security: no standard security certification, or only supports single key level authentication Low security: no standard security certification, or only supports single key level authentication
Connectivity and control stability The adaptive network is immune to the impact of individual node anomalies: through an adaptive deployment method, connections can be established between any nodes without relying on any intermediate routing node. As a result, the network can achieve delay-free recovery when any node fails, thus demonstrating high stability in deployment. A single stable network connection supports up to 4096 nodes Relying on the router, due to the limited number of router connections (generally 10-20), it is easy to drop the line in the whole house when you have multi-devices scenario Relying on the mobile phone Bluetooth connection: if the device uses different Bluetooth chips, there will be compatibility problems Network congestion and disconnection: The protocol adopts a flood-based broadcast mechanism, along with control and heartbeat mechanisms, which is easy to cause network congestion, disconnection and other problems, affecting the stability of the product; a single network with stable connection supports about 50 nodes The impact of a single node is greatly affected: based on the routing connection mode ( between the router and the node, and between the router and the router), if a node (device) is abnormal, the network recovery is slow, resulting in poor control stability; a single network supports about 200 nodes
Connect the linked scene indicators
Scene and linkage support No gateway is required, and problems with a single node do not affect the overall network: distributed scenario design, execution and triggering devices are distributed to relevant devices without relying on the gateway; any abnormal node does not affect the operation of other nodes in the network Relying on the gateway, the response is delayed: it is necessary to standardize the cloud or gateway to collect device data, and the response delay is high. Highly dependent on the gateway: the gateway is the central node, which collects data from each node of the network and performs scenario and linkage control. If the gateway node is abnormal, the whole network cannot work normally Highly rely on the gateway: the gateway is the central node, which collects data from each node of the network and performs scenario and linkage control. If the gateway node is abnormal, the whole network cannot work normally Highly dependent on the gateway: the gateway is the central node, which collects data from each node of the network and performs scenario and linkage control. If the gateway node is abnormal, the whole network cannot work normally
