How many Bluetooth sub-devices can be connected in terms of the central gateway function of the Xiaomi Mesh System BE3600 Pro?

It can connect 100 Bluetooth sub-devices and 200 Bluetooth Mesh sub-devices.
Note:
1. Increasing the number of gateways does not increase the number of sub-device connections. An account supports up to 100 Bluetooth sub-devices and 200 Bluetooth Mesh sub-devices in a physical space (for example, home is a physical space and company is a physical space). If you need to connect Bluetooth devices in other spaces, you need to connect the Xiaomi hub gateway in other spaces as well;
2. For example, in the house with four rooms, use two Xiaomi Mesh System BE3600 Pro to build wired Mesh, up to 100 Bluetooth sub-devices and 200 Bluetooth Mesh sub-devices are supported. In the same space, the number of Bluetooth sub-devices does not stack.
