Hi Ed,
I am able to override and read it back but not seeing any change in pwm data as well as fan speed. I have swampd running.

    Assuming you’re using dbus-sensors (which I’m pretty sure you are):
    Support for overriding sensor values was recently landed in this commit:
    Overriding a sensor value with a "fake" sensor reading should be as easy as simply calling SetProperty on the dbus interface.
    Example as tested on my system (your path names may vary)
    dbus-send --system --print-reply --dest=xyz.openbmc_project.CPUSensor /xyz/openbmc_project/sensors/temperature/Core_1_CPU0 org.freedesktop.DBus.Properties.Set string:xyz.openbmc_project.Sensor.Value string:Value variant:double:1.0
    and verify by reading it back out:
    dbus-send --system --print-reply --dest=xyz.openbmc_project.CPUSensor /xyz/openbmc_project/sensors/temperature/Core_1_CPU0 org.freedesktop.DBus.Properties.GetAll string:xyz.openbmc_project.Sensor.Value
