Hi!

Sorry for the delay.

Please refer to the following link to change the device name：

1. on the overview page of the APP, choose the target client;
2. on the next page, there would be a pen symbol where you could click and change the name;

as for the indirectly way,  I guess you could change the device name on itself, such as the device name of your smartphone;

Thank you very much!
