 -- Monitors TE3 Energy cells and EnderIO capacitor banks and output redstone signals once energy storage drops below set limits.
 -- Will automatically detect direction of adjacent storage device and (optional) Advanced Monitors. If chosen, monitor format should be 1 high and 2 wide. Now also with wired modem support for both storage and monitors. Directly adjacent devices will take priority over any wired devices.
 -- Redstone signal for the engines will be output out the back of the computer.
