Re: Smart streetlight? FFS, why?
Lots of things :
1. Potential failure of the light, current consumption too much
2. Actual failure of the light (no light coming when there should be a light)
3. With a small battery failure of power.
4. meshing together @night to only come on when there is a car /person near the road
5. Placing a pollution monitor on the light, and use this for active traffic management.
