Minimserver behaving abnormally

[simoncn]

In situations like this, it can be helpful to set up a minimal test network with the smallest possible number of devices and connections. If discovery works with the minimal network, you can add devices to the network until discovery no longer works. The last device you added is the device that is causing the problem.

In your case, the minimal network could be your router and the AS5402T (cable connected) and your phone running the LUMIN app.
