Describe the bug

Home Assistant recognizes the addition of the H100 hub, however when I try to configue and enter the app credentials it fails with a message of "FAILED TO CONNECT"

email address used for crediatials does not contain any up case characters, but does contain numbers and an underscore.

Debug log

This error originated from a custom integration.

@JimmyKer, thanks for the pointer, unfortunatley it did not resolve the issue. I followed the procedure noted in the post, but received the same error message. My Tapo app pasword does contain alpha and numeric characters, and meets the minimmum character count, however, my app password does not incude any symbols or special characters. The credentials have always worked previousl when adding a P110 smart plug. To check I have added a further smart plug today with out issue, So I figue there is no issue with the credentials themselves.

The issue seems to be limited to adding the H100 hub, would I be better with the H200 hub? is this supported?

I have got around the issue somewhat by linking to the hub, and its linked device (T110) Smart Contact Sensor via Matter. But I would ike to resolve the matter for the Tapo Integration..

Just as a side note, when I changed the password, my existing Tapo smart plugs would not connect, obviousy due to the change in password, how do I update these for the new password? Not a biggy as I have reverted back to my orignal password, but worth knowing for the future. (I did reboot HA after changing the password)

Ad.

Just to update this, I have found I have to change the Tapo password in the Tapo app when I get this error even if the password doesnt contain special characters. After changing password I can connect again from HA

@Adrian281701 Hello Adrian.. How do you do to configure the T110 via Matter? I am having the same problem, that after I add the sensor, HA stops working.

Do we have to keep changing the password in the Tapo app every time we add a device?
