I think most pieces of this may be done.
The motion sensing outdoor commercial flood lights stink. I had one for several years and it died. Three replacements later, I'm dissapointed with the new versions. The new ones don't last, they stay on durring the day, trigger with no one around ...
Moteino to the rescue. I've collected a tiny 120VAC to 5VDC supply, IR detector, CDS cell, opto triac driver and triac. Soon I'll have Moteino looking at the amount of light, sensing motion and listening for my RF commands. I can have it turn on/off at radom times when I'm away...
I think adding a camera would be nice too.
