Usage

Configuration

Configuration is stored in JSON format. A minimal configuration to send iSpindel data to an http service would look something like:

{
  "serverPath": "/mySpindel",
  "services": [
    {
      "type": "http",
      "url": "http://example.com/endpoint"
    }
  ]
}

In this example the server would listen on the path /mySpindel and forward the iSpindel data to http://example.com/endpoint.

See config.example.json for reference.

By default, the server will look for a config.json file in the root of this project to configure the services to send your iSpindel data to. This can be overriden by setting the CONFIG_FILE_PATH to the full file system path of your configuration file.

Primary Configuration Options

serverPath (optional) - the path for the server. If ommitted, the server will listen at the root.
services (required) - an array of service objects (see config.example.json):
- type (required) - one of:
  - http - the main service which can be used to send data over HTTP or HTTPS:
  - ubidots - Ubidots
  - homeassistant - Home Assistant
- url (required) - the URL to send to
- deviceLabel (optional) - rename the device from what is configured in the iSpindel. Used for services like GrainFather and Brewfather which require a specific string in the name when using SG instead of Plato.
- headers (optional) - a key-value object of headers and header values to send with the request
- token (optional) - the API token to send in the request for supported services (currently only used for ubidots and homeassistant)

Using Environment Variables in `config.json`

Since the configuration may store sensitive information, it is a good idea to use environment variables for this info instead of storing it in config.json. This allows you to version control your config without worrying about leaking keys or secrets.

To allow this, we use envsub for environment variable substitution using the ${MYVAR} format. For example, if you were using ubidots as a serivce, and set your Ubidots token in the UBIDOTS_TOKEN environment variable, your config.json would look something like:

{
  "serverPath": "/mySpindel",
  "services": [
    {
      "type": "ubidots",
      "deviceLabel": "iSpindel",
      "token": "${UBIDOTS_TOKEN}"
    }
  ]
}

Running the Server

Deploy to your favorite node.js hosting service (see guide for deploying to Render).

yarn
yarn start

The server will listen on the port specified with the PORT environment variable or 8080 if not set.

Running the Server for Development

git clone https://github.com/chrisscott/iSpindel-multiservice
cd iSpindel-multiservice
yarn install
yarn run dev

The server will listen on the port specified with the PORT environment variable or 8080 if not set.

FAQ

What does this do?

Provides a service you can point your iSpindel to which then forwards the data to one or more supported services.

Why would I need it?

You have an iSpindel and want to send data to Ubidots, Grainfather, Brewers Friend, a custom HTTP service, Home Assistant or more.
You are on an old iSpindel firmware without HTTPS support want to send iSpindel data to a service that only supports HTTPS.

Which services are supported?

Currently, the following:

HTTP - any HTTP or HTTPS endpoint
