That's was my second idea. The problem is that I read from the forum that there are 3 different models and only 2 models works with Indigo 6.
Two possibilities:
1. Buy Indigo 7, but at the moment I do not have the possibility to do troubleshooting if something goes wrong (and in two weeks I will leave for holidays)
2. Buy Fibaro Wall Plug, I will connect the fridge so that I can control if it goes OFF, but here I have my doubts: I think I am missing something, because if the fridge will shutdown because of power failure (and then also the Fibaro Wall Plug), I cannot get any notification.
And, with solution #2 there is one more risk, that the Wall Plug fails and the fridge goes off
