How could I use Alexa to grind coffee?

I’m a huge coffee addict and have a nice burr grinder to grind my beans, however the control switch has broken so now the grinder just grinds continuously when I turn it on at the mains. I’ve just been switching it on and off from the mains to grind and I’ve worked that I need to grind for 12 seconds to have the right amount of ground coffee for my morning brew. I have an amazon smart speaker in my kitchen. Is there a smart plug solution that will allow me to say “Alexa, grind coffee” and it turn on the coffee grinder for exactly 12 seconds? It would save me spending £80 on a new grinder and also be pretty cool.
