ioBroker.shelly [Bug]: Wrong MQTT authentification of client

I'm sure that

[X] There is no other (open) issue with the same topic (used the search)
[X] This issue is not described in the adapter documentation / FAQ

Shelly device

shellyplus1pm 1.0.8

Protocol

MQTT

The problem

It's my first device on this adapter. I make this connection with an easy password '123456789' without some special characters. I setup this username and password to the mqtt settings fom the adapter.

i found the problem. i change back the username to "admin". i see the this in the code

lib/protocol/base.js:

i think the problem is at line 125 for gen2 devices. const username = 'admin';

for gen1 you take this at line 86: username: this.adapter.config.httpusername,

You've mixed two topics in this issue

Authentication against the Shelly (see restricted login documentation)
Authentication of MQTT clients against ioBroker (see mqtt documentation)

i found the problem. i change back the username to "admin". i see the this in the code

As documented, Gen 2 devices don't have a username. The username is always admin. So you don't have to change anything in your configuration "back to admin". The username (for restricted login) is just used to authenticate via HTTP against Gen 1 devices.
