This question had my girlfriend several times to move to go back home. I wanted her soul now to do something good and wanted hattte weeks for a solution, I wanted a wake Switches / Relays buy and build in a more or less fancy housing. But then I found this great specimen. There are 2 setting switch with which one: 1. Adjust the length of the delay (1/2/4/8 Hours) 2. set whether it should after the time on or off We use now since over a month as follows: One of us is on tapping with your finger on top. You can hear a clunk from the relay and a green LED indicates the switching status. The coffee maker will heat going. We make coffee. An hour later, the unit switches off the coffee machine.
"Have I turned off the coffee machine?" - "Nope Nevertheless from it." My only gripe with the device that could light up the LED bit brighter. Especially with very bright lighting conditions, the switching state is difficult to detect.
