What does the "Link+" feature in the HUAWEI SmartHome app's router management page do?

The Link+ feature allows you to view the topographical structure of your SmartHome network (including main and secondary routers and connected devices) as well as performing the function of a H button by allowing you to add HiLink devices to your SmartHome network at the touch of a single button.

If your router supports the Mesh feature, a Link+ diagram will be displayed. The following diagram uses the HUAWEI WiFi Q2 as an example. Actual image may vary based on your router model.
