For those landing here looking for a way to add #states to field_groups in a more generic way via traditional form_alter_hooks, the below helper hook works well.

/**
 * Implements hook_field_group_form_process().
 */
function my_module_field_group_form_process(array &$element, &$group, &$complete_form) {
  /**
   * Provides a generic way for assigning Form API #states to field group elements
   *
   * @usage - In a from_alter hook the Group object can be added to include a form_api_states property,
   *          which is picked up here and applied to the field group element
   * @code
   *  $form['#fieldgroups']['group_my_group']->form_api_states = [
   *     'visible' => [
   *        ':input[name^="my_field_name"]' => ['checked' => TRUE],
   *      ]
   *    ];
   * @endcode
   */
  if (isset($group->form_api_states) && is_array($group->form_api_states) && !isset($element['#states'])) {
    $element['#states'] = $group->form_api_states;
  }
}

The hook hook_field_group_form_process works ok for me too.
