I've been a loyal Kasa user for years now. I recently picked up another HS300 as I needed to replace a KP303 that I have tied in for Automations with Home Assistant. I seem to be having an issue where I keep getting the following when trying to connect and login to the device. "Unable to authenticate: Device response did not match our challenge on ip 10.1.x.x, check that your e-mail and password (both case-sensitive) are correct." I have confirmed they are 100% correct as I can log into the web portal just fine. 

Reading it says I can uninstall and reinstall but I simply cannot accept that as an answer and have to rebuild 10's of my Automations, also I don't want to rely on the cloud access to the devices for my local Automations as I segment my IoT VLAN to not have any internet based access for security. Is there a way to get this working?

I'd really appreciate any assistance.
