ACPIPMTR(4) BSD Kernel Interfaces Manual ACPIPMTR(4)NAMEacpipmtr — ACPI Power Meter
SYNOPSIS
acpipmtr* at acpi?
DESCRIPTION
The acpipmtr device driver provides support for “power meters”. These
are sensors that approximate the current power consumption of the system.
Alternatively, a power meter may measure also the power gain when the
system is connected to an external power supply.
The available information (namely, the power consumption) is made avail‐
able through the envsys(4) API and the envstat(8) command.

The acpipmtr device driver appeared in NetBSD 6.0.
