Habpanel - make it read only

I’m thinking about using a real old iPhone as an information only screen for showing the state of the central heating (at this stage).

Our central heating can be scheduled, on or off. And based on that selection and Te,p + time of day, a switch is thrown to turn it on.

What I’d like to display is the schedule state (the tri state) and the state of the switch. But I don’t want it interactive.

Is there a widget for thud, or do I need a new item updated by rule….though if I dud that and then in the habpanel the switch was set off, how dies it get updated back to the true state again?

I can’t answer the question but I’ve moved the thread to a more appropriate category.
