Never miss important mail again:
Once something is placed in your letterbox, the H2 Letterbox sensor will notify you via 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 letterbox sensor, you don’t have to check your letterbox constantly, and you won’t waste any time.
Small and practical:
The H2 Letterbox sensor fits all letterboxes with a flap. In continuous operation, the expected battery life is around two years.
