Snarky Doorbell

Snarky Doorbell is an IoT doorbell with an attitude. Instead of a monotonic "ding-dong", it responds with a snarky voice comment whenever our office doorbell is rung.

Read a longer blog post on how this was built, or watch a project build video from YouTube.

Features

• Several custom voice personals ("Easily excitable manager")
• Settings (voice, language, volume) can be changed via buttons on the front panel
• Built-in WiFi HTTP RESTful API server (statistics on doorbell rings)
• Open source project plans
• Non-intrusive integration with the existing doorbell system (uses the same doorbell button)

Project Structure

• ansible/ - Ansible playbook for installing and configuring the Raspberry "brain"
• doc/ - Misc documentation files (voice persona lines)
• firmware/ - Arduino firmware for the doorbell RF receiver module
• hardware/ - Hardware schematics
• src/ - Python daemon (doorbell controller) and webserver code for the Raspberry
