Hello everyone,

I’m a newbie but I’ve already a dashboard working and commanding things with Habpanel.
Anyone can help me please developing a widget to a dashboard that shows if a state of a thing is offline or online and when the last log ocurred?
I trying to detect zigbee things that stop communicating with the gateway and OpenHab.

Thank you everyone in advance

Habpanel is not the correct place for that. For what you want to accomplish, you need to create a rule that updates a DateTime item when your item changes.

Switch mySwitch
DateTime mySwitchLastChanged
rule "Update last changed"
	Item mySwitch changed
	mySwitchLastChanged.postUpdate( new DateTimeType() )
