make your letter box truly smart

Never miss your mail again with the H2 Letterbox Sensor!

Anyone living on an upper floor or who has to pass through the yard to get to their letterbox will appreciate the H2 Letterbox sensor: The app notifies you once mail lands in your letterbox. This way, you will never miss important letters or packages.
  • Easy operation:

    Hardly any system is as fast and easy to install as the H2 system. The H2 Letterbox Sensor is ready for use in just a few steps.
  • Never miss important mail again:

    Essentially, the H2 Letterbox sensor is a mail carrier who rings your smartphone: Once something is placed in your letterbox, you receive a notification on the app. This means you can get to your important mail as quickly as possible.
  • Indispensable for company letterboxes:

    Registered mail, appointment letters, requests and quote confirmations — it’s important to be able to respond quickly, especially for small companies. With the letter box sensor, you don’t have to constantly look in your letterbox and you won’t waste any time.
  • Small and practical:

    The H2 Letterbox sensor fits to all letterboxes with a flap. In continuous operation battery lifetime remains at about 2 years.
