Power Outage Notification Device ?

[Robert Posta]

I was not sure where to place this post.   I figured property management may be best . 

Does anyone use or know of a reliable device that would send notification when power went out to a certain outlet ? 
Mainly trying to monitor refrigerators.   Had an instance on a vacation home where the circuit breaker tripped and the fridge smelled really bad  when we finally had someone go look at the home.  The fridge was out for 2-3 weeks. I did some research on Amazon and found a few products that had "OK" reviews.  Would love to hear if anyone on BP has a device that works well for them.  THANKS.
