I just upgraded to EISY and Kasa is one of the first node servers I have installed, although I had WeatherLink running on Raspberry Pi earlier. I have been having similar problems as above with the HS300 power strip, with the admin console showing Kasa connected, but no nodes appeared. I have Iox 5.7.1, Kasa 3.1.4, PG3x 3.2..16, udx ?.? (don't know where to find that one). I finally installed the Dev packages, reinstalled Kasa node server, restarted everything, and the power strip appeared in the admin console, so now it is working fine. Thanks for all the background and answered queries above.
