I realized my long-time dream :)
The BBB?
Aaa: The light was cut off all over the house.
Did you have UPS?
A: It will happen to a neighbor - to find out if there is light or not.
I open... in one room music is played (on the notepad) from another room - light (the child's lamp is connected to the UPS) from the kitchen clearly heard TV - news is broadcast (from the iPad to 3G). The question is, do you have the light? The answer is NO! I close the door... I look in the eye – standing in the shower – trying to understand what it was...))))))
