user name and/or password are wrong? Not much we can say about anything here.
What user name does it need? It's own or the one I login as? I've been using it for 4 years and have never had to configure this addon.
you could add a new user ...depending on your unknown setup. you could try sending mqtt test packages from your terminal or any mqtt tool. that would narrow down the problem a lot.
Here are some more screenshots.
Click the "Documentation" tab and it has instructions on how to get it set up. 👍
This. Basically few addons are ‘fire and forget’, almost all of them need some sort of configuration that’s listed in the Documentation tab, or in the add-ons repo. You’ll need to read up on it and look at the Configuration tab to set whatever you need to allow it to work.
