TPLink/Tapo L530E bulbs not adding to HA after Discovery

[OrangeGitHubber]

The problem

I recently bought four Tapo L530E bulbs. Added them to the Tapo app and can control them from the app. In the same Tapo app I can also control other TP-Link/Kasa Devices.

Once the four new bulbs are added to the Wifi and Tapo app, they appear as discovered in Home Assistant. When I click on Add The username and password prompt comes up. I enter the same credentials I use for the Tapo app but it results in the error message.

I followed the instructions here , but it did not help either. 3rd Party Integration is on, and TFA is off.

Anything in the logs that might be useful for us?

All other original Kasa switches and bulbs still work, just these four new Tapo bulbs.

Could you find the part of the log where the device 192.168.120.107 responds to DISCOVERY? Are you sure you're using the correct credentials (case-sensitive)?
