Dear Esteemed Wrenches,
This issue arises periodically, and I'm hopeful someone in the group has
devised a cost-effective, low-power solution.
For a whole-home backup system, how can we best alert homeowners that they
are operating on battery power? These homeowners do not use smartphones and
won't receive push notifications. Is there a simple solution to activate a
single light or audible alarm exclusively when the grid is down? This
particular instance involves a FranklinWH system, but the same challenge
applies to any battery with a whole-home backup and "instant-on" transfer
switch.
Thank you in advance for your insights.
Sincerely,
Nicholas Ponzio
