Customer travels extensively. He has come home more than once wanting to use the hot tub, only to find out that the breaker has tripped and the water is not hot. It is also very important to prevent freezing in the winter. The breaker is a 220 volt with arc fault. The arc fault is the culprit... The electrician does not want to change out the the breaker to a non-arc fault which is understandable. I can monitor the breaker for power with a relay and a wireless alarm transmitter. Homeowner would like to monitor water temp as well.

Anyone done this before?
