I hadn't thought about insurance requirements. Guess I should check my
policy. Getting someone to do a regular check is very unlikely. Switch
controls such as Insteon or Z-wave can be signaled by a controller which
can be stand-alone or programmed from a PC or smartphone. A simple
programmable controller can be had for under $100. More sophisticated
ones at about $300.
I've never seen a photo-sensor/timer controller.
