I have a coffee machine that uses a significant amount of power and is often not switched off. Therefore I'm looking for a device that is able to switch off the power after a certain amount of time (say 30 minutes). I found some countdown timers, such as
However, they all have the same problem: they require interaction to be activated.
Ideally, I would like to set the countdown time in advance, turn on the coffee machine (and have no interaction with the countdown timer), have the countdown timer start as soon as the coffee machine starts, and then kill the power after the programmed time.
I was wondering if anybody knows a device that can do this, or has a solution for this kind of problem?
