With python-kasa 0.5.4 installed (part of Home Assistant 2023.11), I'm no longer able to connect to my HS103 devices. I installed the package on my local machine, and I can reproduce the issue. I saw #543, but it seems like a different issue for me, since I am using the IP address and not hostname.

With 0.5.3, "kasa --host 192.168.40.5" finds the device and provides the device information. With 0.5.4, I receive "Got error: SmartDeviceException('Timed out getting discovery response for 192.168.40.5')".

As mentioned previously, the device is on a separate IOT subnet for me. Perhaps that is making the difference? Please let me know what I can do to help troubleshoot!
