I dont think so. The talent doesnt say anything about sharing your senses. Even a familiar gained from (Greater) Elemental Whispers doesnt automatically share senses... it shares emotions, can eventually speak with you, and eventually you can scry on it, but you cant see through its eyes or hear through its ears, etc.
So the way I understand the basic version is, you summon the elemental and then must spend your move action to "direct" it. Directing it probably means stuff like "go to x", "kill this enemy", "come back", and similar. I think even a command like "go to x, kill this enemy, and then come back" would be valid, as long as you keep spending your move action on it every turn until the task is finished. As soon as you do something else with your move action, it collapses on itself and the spell ends. So even if the elemental is out of sight, you can always command it to come back, or to move to a location that is in sight. But you dont sense anything that the elemental does.
If you pour your sentience into it, it acts on its own, freeing your move action. You can probably give it directions as before, and it would probably try to execute them to the best of its ability. It still doesnt say anything about sharing senses though.
