@Kevin_Z Kasa Version 2.15.0 Build 697, there is no error message other than it saying "Please connect your iPhone to your WI-FI network to continue setup", this is the same message you get...

@Octron Same problem here, I have an HS110 and HS105 that setup does not work for in IOS13. Got them setup on an Android device and at least the switch on/off functionality in the IOS app works.
