Countdown timer widget

Otherwise, you’re going to need to use some feature outside of the widget system (e.g., a rule to do the actual timing and change an item accordingly).

OHRT has a countdown timer which populates a String Item or a Number:Time Item with how much is left on the scheduled timer. The value is updated once per second.

For Blockly users see openHAB Rules Tools [4.1.0.0;4.9.9.9] (countdown timer is the first one in the list).

From there I think it’s just a matter of showing the Item which the remaining time on the Timer in a widget and you are good.
