Hi,
I added the component into my custom_components folder and I add my Tapo credential into the configuration.yaml but the device is not there.
The error is:
Questo errore ha avuto origine da un'integrazione personalizzata.

Logger: custom_components.tapo_p100_control.switch
Source: custom_components/tapo_p100_control/switch.py:41
Integration: tapo_p100_control (documentation, issues)
First occurred: 17:57:01 (1 occurrences)
Last logged: 17:57:01

Could not connect to plug. Possibly invalid credentials

My tapo firmware is: 1.4.5 build 20210122 rel 57265.
Hardwere verion: 1.20.0
I used a psw with only 8 chars.

Please, could you help me to solve this issue?
