After having sought information on the syntax of the MQTT configuration I submit my research and results to you
with the correlation between the text mode declaration in Thing-items-sitemap and the visualization in PaperUI Items:
I you had configured your channels in the paperUI directly instead of a things file you would never have had to worry about the syntax and got it right the first time.
True, the mistake was in going with a things file in the first place which is not recommended (and documented as such).
Then again, I just tried looking this up in the docs and found there’s no (complete, understandable) syntax definition with the binding docs and NO examples. @Confectrician I’d call that a docs bugs, wdyt ?
In fact it is simply because I like to get to the bottom of things and understand very exactly what I do, actually I first used the declaration under PaperUI but I did not understand the information given and often very different in the various subject posted and therefore it is for the sake of clarity that I studied the real syntax and the relationship between manual declaration and PaperUI and I posted it to benefit others
Mqtt Binding Docs were written with UI focus iirc. The binding author doesn’t use textual configuration at all as far as I know.
But I have not looked into them for now.
Of course any clarification in the binding docs can be helpful.
The correct place for this would be the add-ons repository.
I agree with the others about using PaperUI to avoid mistakes but I’m bookmarking this topic so I can reference it for all the hardheaded files only users.
This should help to reduce the amount of post needed to get someone up and running.
