This is not an issue but a question, please use our gitter channel for this.

To answer the question though, you use it like this:

webdriverio
  .remote(options)
  .init()
  .url('some-page')
  .element('#some-input')
  .setValue('some value')
  .getValue('#some-input').then(value => {
    console.log('Value was: ', value); // logs "Value was: some value"
  })
  .end()
  .catch(function(err) {
      console.log(err);
  });

This can be related to the repl interprets the return value. Let's reopen.

@jiangyd note that we are working hard on the new WebdriverIO version so we can't look into fixing a bug of a version that will be deprecated soon. We are happy to accept pull requests that fix the issue.
