No machine.wake_reason() for lightsleep?

[railmonitor]

Hi all.

As the topic states, is there a machine.wake_reason() for lightsleep?

I am using lightsleep for my FiPy, which is enabled using:

machine.sleep(5000)

this puts my FiPy in lightsleep for 5 seconds. If i try to get the wake reason using:

print("Wake Reason: "+str(machine.wake_reason()))

the result is: Wake Reason: (0, None). This is the result no matter if i just let the time run out, or if i wake it from acceleromeer which i set up and is able to wake the system up from lightsleep.

What i basically need is to be able to check if a wake_up from lightsleep was triggered by the sleep interval running out, any ideas?

Thanks!
