That is blatant false advertising. This is a very good case of bait and switch advertising. I built my entire lawn’s watering system around these devices under the assumption I could add a hub later since the box clearly indicates that is possible. If your company does not intend on releasing the hub individually, then you pulled a bait and switch on your customers. That type of practice is illegal and I intend to report it. Please have someone in your support department contact me as soon as possible.
