Power & Electrical System

Overview

The Power section of the cee API manages electrical power, voltage levels, current limits, and device states across pins and networks in CC: Computer Energetics.

Calling Conventions / Prefixes

Power utility functions and measurements are accessed through the global cee namespace:

local volts = cee.getVoltage(1)
cee.setMainBreaker(true)

API Reference Table

Method Signature	Arguments & Types	Description
`cee.getVoltage(pin)`	`pin` (number)	Returns the average voltage on a pin over the last second.
`cee.getCurrent(pin)`	`pin` (number)	Returns total current flowing through the pin.
`cee.getPower(pin)`	`pin` (number)	Returns real power in watts on the pin.
`cee.getApparentPower(pin)`	`pin` (number)	Returns VA (volt-amps) on the pin.
`cee.getReactivePower(pin)`	`pin` (number)	Returns VAR (volt-amps reactive) on the pin.
`cee.getPowerFactor(pin)`	`pin` (number)	Returns the power factor on the pin (-1 to 1).
`cee.getFrequency(pin)`	`pin` (number)	Returns frequency in Hz of the pin's AC wave.
`cee.getPhase(pin)`	`pin` (number)	Returns phase offset in degrees.
`cee.getMainBreaker()`	None	Returns whether the computer's main power gate/breaker is up.
`cee.setMainBreaker(bool)`	`bool` (boolean)	Trips or resets the main breaker.
`cee.getBreakerReason()`	None	Returns why the breaker tripped, as a string table.

Lua Code Examples

Example 1: Checking Pin Voltage and Power

local pin = 1
local v = cee.getVoltage(pin)
local w = cee.getPower(pin)

print("Pin " .. pin .. " Voltage: " .. v .. "V, Power: " .. w .. "W")

Example 2: Managing Main Breaker State

if not cee.getMainBreaker() then
    print("Breaker tripped! Reason:", textutils.serialise(cee.getBreakerReason()))
    print("Attempting to reset breaker...")
    cee.setMainBreaker(true)
end
