Thanks… I checked the docs, but can’t make sense of them.
It says: Profiles can be specified as a parameter for a given Channel on the Item configuration
There is neither a profile option in the item config
… nor is it in the thing config.
Given the example, which is for a text-based config:
<item-type> MyItem { channel="<bindingID>:<thing-typeID>:MyThing:myChannel"[profile="system:<profileID>", <profile-parameterID>="MyValue", ...]}
This implies some sort of template needs to be created for the profile… and then applied to, presumably, ‘thing’?!
Configure thing does not have an option for profile in the UI.
Sometimes I doubt moving to UI config was the right thing to do (as in moving away from text-based config).
[edit 1]
Rereading the items doc page, I found this:
DateTime Bedroom_Light_Updated { channel="hue:0210:1:bulb1:color" [profile="system:timestamp-update"] }
This is probably what you were referring to. So where do I add this in the UI?
[edit 2]
I found this post, which at least describes how to get to the profile assignments.
I have never been there; Model that is.
It looks like this:
I see only 5 “Last update(d)” points, but have probably 50 of them; where are the others?
This screenshot also shows a date item linked to a number channel, which is what I cannot do anymore on newly created (MQTT Generic Thing) channels.
See here:
WHAT?!
Now it lets me!!!
Dang.
Did I make to many change and the JSON db had to catch up?!!!
What is going on here?
In any case, let’s forget how to link a date item to a number channel. But finding an answer to the question on how to do the profile, ideally at a different place than the Model page would be great.

Sometimes I should look better 
It is right there…
