petfeedd is a daemon for Raspberry Pi that will feed your pets. :)

Well, okay, obviously, it won't physically feed your pets. You'll still have to build the hardware part of the feeder. But it aims to wrap up the common functionality that pet feeders require into a format that can be reused for any number of feeder designs.

petfeedd provides:

  • A web interface for "programming" your feeder, that allows an arbitrary number of feeds of an arbitrary size.

  • A RESTful API that can be used to write third-party clients.

  • An auto-discovery protocol that can be used to find feeders on your network. Useful for writing third party clients.

  • A notification system that supports email, MQTT and Twitter.

petfeedd is implemented in NodeJS with Vue for the web front end.

A Note About Security

Let's have some common sense here. This is a pet feeder. Do not expose it to the Internet. It implements no security on the web interface. There are no users or passwords or API keys. Again, it's a pet feeder, not a banking site. Keep it safely behind your firewall.

If you are truly paranoid about this, you can use nginx as a proxy to add HTTP authentication, or simply not expose the web interface once you have it configured.

Supported Hardware

petfeedd is reported to be working without modification on:

  • Raspberry Pi Zero
  • Raspberry Pi Zero 2
  • Raspberry Pi 3
  • Raspberry Pi 3B v1.2
  • Raspberry Pi 3B+
  • Raspberry Pi 4

I generally recommend not using the Zero for a project like this. The limited onboard memory tends to be problematic.



Patches are always welcome if you have some cool functionality you would like to add.
