Method: CurrentCost::Meter#latest_reading

Defined in:
lib/currentcost/meter.rb

#latest_reading ⇒ Object

Get the last Reading received. If no reading has been received yet, returns nil. If you have registered an observer with add_observer(), you will most likely not need this function as the reading will be delivered automatically to your observer’s update() function.
