Delay timer for switch

Also, would be nice if there was a countdown timer visible in the UI with time remaining until the light goes off.

take a look at node-red-contrib-mytimeout that you could feed to a change node to change the time to hh:mm format then to a ui_text node. You could also send it to a ui_guage in donut mode to have a visual countdown. That is what I juse in my Coffee Pot Timer project
