I’m trying to use proper-case (Off vs. OFF) on HabPanel dummy items tied to groups. Is there a way to transform group items? If so, can you provide the syntax for it please . . .
just tried to achieve this over the MainUI ( 4.1.0.M4), but I dont have an option to select transformation for a group Items via ui. That only is possible when I have linked a thing channel…
You don’t have that option for an Item either. It’s important to understand the parts of the flow:
Thing: represents the device
Channel: represents a single sensor or actuator on the device
Link: connects a Channel to an Item
Profile: works at the Link to modify or otherwise manipulate the state updates flowing from the Channel to the Item and commands from the Item to the Channel
Items: represents the sensor or actuator within OH
The transform Profile can only be applied at the Link. But that isn’t the only place a transform can be applied.
To apply a transform at the Item level you use the State Description metadata’s Pattern field. In .items files you’ll use the label field. See Items | openHAB. This works for any type of Item, inclduing Groups.
You can also apply a transformation on some Thing Channels and within rules.
