HS100 Hardware V4.1 Firmware 1.1.0 - No Detection Even When IP Manually Specified
Maybe a duplication or similar to https://github.com/plasticrake/homebridge-tplink-smarthome/issues/153

All HS100 Hardware V4.1 devices suddenly stopped working (work fine from Kassa App).  Have reset them, have tried different versions of plug-in and config settings.  Even manually specified devices.  I have also reset homebridge.  They now do not discover or show up.

I think this is possibly due to a firmware update from TP Link.  I have a selection of HS100 devices some on hardware 2.0 and hardware 2.1 (these are all working).  

### Expected Behavior
The device appear in discovery or when manually specified

### Current Behavior
Device does not appear

### Steps to Reproduce (for bugs)
Setup a HS100 with hardware V4.1 and Firmware 1.1.0 device will not appear.
