Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(name, *args) ⇒ Object

Invokes event(_at) for any sensor

Raises:

  • (ArgumentError) —

    unless sensor exists

#sensor(name) {|sensor| ... } ⇒ Object

Returns previously initialized sensor by name

Parameters:

  • name (Symbol) —

    sensor name

Yields:

  • (sensor) —
