A method and system for dynamically controlling operation of a first device, the first device being configurable to respond to receipt of primitive user input (e.g., push of a button on the first device) by carrying out a control action with respect to one or more second devices. An example method includes detecting a context state such as time of day and/or location of the first device. Further, the example method includes, using the detected context state as a basis to control what control action the first device will take in response to the first device receiving the primitive user input, such as which second device the first device will control in response to receiving the primitive user input and/or controlling what operational state of a second device the first device will control in response to receiving the primitive user input.
