The LAN’s instability causes frequent changes in its topology, leading to control failure.

For example, node [%s] ip[%x] leave, where the content enclosed in [] is the node and IP address of the gateway. If this message appears in the log of the main gateway, it indicates the node leaves the LAN.
When the gateway and the central control are in the same home, the central control serves as the main gateway for LAN linkage. However, if the central control is not using the latest firmware, it cannot deliver LAN messages to the gateway. Contact the central control manufacturer to update the central control.
