Invalid Request or Credentials

[remusgondecjr]

Hi,

I'm trying to set this up for one of my Tapo P100 plugs but I get the following error:
"Exception: Error Code: -1501, Invalid Request or Credentials"

I'm sure that credentials are OK. I even tried changing my password, it works on the Tapo app, but not in home assistant.

Hey, does your password have any special characters in it? And have you tried a password reset in the app?

[remusgondecjr]

Yes, I did try a password reset in the app, but no luck. Tried different passwords, also without special characters but still no luck.

It looks like there is problem with passwords longer than 8 chars.

I also had a problem with Exception: Error Code: -1501, Invalid Request or Credentials with Tapo L510E bulb.

Firstly I got old firmware when I was configuring bulb on Tapo, after configuring it I upgraded to newest one - 1.1.7 Build 20201029 Rel. 40821

With this version I get -1051 error.

After that I changed password to 8-chars (was 12 chars previously) and verified again - nothing changes.
So I removed bulb from Tapo app and re-added it.
After this change the bulb started to work from HA.

I've also been having the same issue with credentials not being valid.

Can confirm that removing and then adding the plug back into the app worked for me (also be careful you don't get yourself locked out of the account)..

The PHP library tp-link-info by jacobkossman doesn't have this issue..

I also managed to get it working after some trial and error. And I think there are 2 issues here.
1 - It won't work with a password longer than 8 characters.
2 - the device needs to be removed and re-added to the app for the password change to take effect. This is what had me so confused!
I verified this by changing my password again, but HA continued to work having the old password in the config file. When I once again re-added the device, HA stopped working with the same 1051 error.

Just did the exact same. Changed password to 8 characters, and readded the plugs. They now show up as entities.
