Hi Lew,

When I am home, I can easily continue to do what I do now:

The power goes out (often ice storms, but about a week ago a
fellow drove into a pole), and I fire up my portable Honda
generator, connect it up, and rest easy.

The issue is that we are often away from our home...

I am trying to find a reasonable way to protect our place
from freezing, and flooding, in that situation.

See my post SCADA
