Main change state method

module.exports.change_state = function(state, time, brightness) {
  console.log(state, time, brightness);
  light.send({
    'smartlife.iot.smartbulb.lightingservice': {
      'transition_light_state': {
        'on_off': state,
        'transition_period': time,
        'brightness': brightness
      }
    }
  })
  .then(response => {
    console.log(response)
  })
  .catch(e => console.error(e))
}

Here method to change state by API, take 3 parameters: state (0/1), time (how much time should be a transition) and brightness (0-100)

In server.js in method javascript app.post() big switch case, wich takes parameters from post-request body for find solution, after finding use javascript change_state(s, t, b) or something else
