I believe this is already supported in the entity-manager/dbus-sensors
stack, with the "PowerState" parameter in the EM configuration;

example:
https://github.com/openbmc/entity-manager/blob/def29274907ef77187b02ae19d55bb9888413892/configurations/WFT%20Baseboard.json#L6

There's also mitigations for the common thresholding issues, like a
power state change coming in during the sensor read.
