I sure wish there was a wireless way to monitor multiple circuits for outages. The one's I glanced at were worth more than my car. :( My son-in-law has about $8,000 worth of lobsters and red snapper stored in the three freezers.
There's a little gem called the ESP8266, hot item right now from China. It is a microcontroller with a WIFI radio built in. The tools to program them are a $5 USB serial cable and a free download from the Internet. Best thing? They're about $3 each at qty 10.
Connect to the N/O contacts of a line powered relay and presto, chip turns on when the power goes out. Have one more back at the ranch listening, with a big buzzer connected.
Excellent share there, Gordon! Thanks again!
