The idea is simple

• Print off your doorbell QR code and stick it to your door, gate, or building entrance
• Visitors scan the code with their phones
• You get an alert via email or notification to let you know that someone's at the door - no more missed deliveries!
• Visitors can leave a message if you do not wish to be disturbed, it will be sent to you via email or in a notification
• Privacy conscious - no video stream of you and your home being broadcast online
• Notify up to 3 email addresses or devices for free, or go premium for just $0.5 per month to let visitors leave a message or photo, schedule quiet times, customize your doorbell, and more!
• Support for the ntfy app for instant notifications to your phone, tablet, or PC
• New premium feature! You can now set an access code or schedule do-not-disturb hours to restrict who can ring your doorbell
• Developers can even configure webhooks to build their own custom systems
• Netherlands supported!
