Home Assistant Firefly Budget Alerts

Goal

My spouse asked me the other day if I could set up real-time notifications for our Firefly III budget status. As a satisfied user of both Firefly III and Home Assistant, a combination of the two seemed like a natural fit, given Firefly's extensive API and Home Assistant's flexible notification capability via the companion app.

Turns out it's not hard to accomplish the goal via a Node-RED flow.

Setup

1. Import flow.json into your Home Assistant Node-RED as a new flow.
2. Set the global context value fireflyUrl in your Node-RED config to the base URL of your Firefly install, i.e. https://firefly.example.com.
3. Set up a localfilesystem context storage module named store in your Node-RED config, for instance as below:
   1. You can name it something other than store, but then you need to replace all the references in flow.json.

  contextStorage: {
    store: { module: "localfilesystem"},
    default: { module: "memory" }
  },

4. Profit.
