What you can’t do (yet)

• You can’t read the total power of a furniture grid or list the devices of a grid. (FurnitureManager.NetPower and the per-manager device list are not available to mods.)
• You can’t read a power draw for crafting stations or batteries. The game does not use one. (PowerSource.powerConsumption is not used by the game.)
• You can’t list which items a battery accepts as fuel. A battery accepts fuel by item kind, not by a list of item numbers. (BatteryPowerSource.fuelType is a flag set, not item ids.)
