Kasa TPlink integration wont authenticate

Configuration
1

My Kasa tplink integration keeps saying authentication has expired. When I try to put in my credentials I get the following message

“ Unable to authenticate: Device response did not match our challenge on ip 192.168.20.179, check that your e-mail and password (both case-sensitive) are correct.”

I can use those exact credentials to logout and log back into the iOS Kasa app as well as to login into the Kasa cloud service. For some reason they will not work in home assistant. I have tried playing with different case in the username with no success.

Any assistance in solving this issue would be greatly appreciated

Thank you

Hi, welcome to the forum!

Have you seen this: TP-Link Smart Home - Home Assistant
I’ve seen quite some topics on this in the past but don’t have any info at hand to help you.
Check Search results for 'kasa tp' - Home Assistant Community

Thank you for your reply.

Yes I have taken a look at that link and looked for other forums detailing the same problem I am having but have not had any luck find a solution.

Thank you for the information

I think at this point I might have to delete all 37 of my kasa light switches in home assistant to fully delete the integration ?? And then reinstall?

Anyone have an update on this? I am having the same issue. Both issues are motion switches. I have probably 15 other Kasa devices that don’t seem to have this issue and working fine.
