Yes, the gateway supports cross-gateway linkage. When it comes to cross-gateway linkage, the following conditions need to be met: the devices are located under different gateways, and these gateways are all within the same local area network (LAN). In this case, the Master gateway takes charge of the linkage, also known as LAN linkage. Even in the event of a network outage, the linkage can still be executed.
If the conditions for LAN linkage are not met, the linkage will be handled by the cloud, and can only be executed when the devices are connected to the network.
