I realize that my last message is absolutely incomprehensible…
But while reading the topic about the possibility for integrations to declare their own widgets, I already found an answer to part of my questions.
If I understand correctly, today, we cannot really « plug in » information or actions into Gladys that do not exist in the Gladys core. And, consequently, we cannot really display them in the dashboard or use them in scenes either.
This is exactly where I agree with the topic of widgets: if, in the future, an external integration could declare its own data, actions, and possibly triggers, we could then have an integration capable of filling in any gaps in the Gladys core, without necessarily having to add each specific feature in Gladys.
So, I think that it is rather this interaction between the core and external integrations that I was trying to understand in my previous message.
