Do you have a smart things hub? If so, you could use CoRE and create a piston where you can set it to turn off X minutes after it turns on. That way you make sure its only on for a few minutes.
If Coffee maker switch turns to on
Then using Coffee make switch
WAIT X MINUTES
TURN OFF
For your post lunch case, If you have an Amazon Echo, you could say something like “Turn the coffee maker on” and that should switch it on. Once again, the CoRE piston in place will make sure it turns off after X minutes.
I do have a smartthings hub, why would I be here if I didn’t? Lol!
About the CoRE… I’m not much of a programmer so you kinda lost me there… but it sounds like what I need!
And about the Echo, yup, that could be it, if Amazon would start selling it in Europe! Lol!
EDIT: How about a physical switch like the Hue Tap to turn it on/off? Would it do? I refer to the Tap because that one doesn’t require electricity… as far as I know…
