Module: Check Status via JSON API Calls (MMM-JSONStatusChecker)

This is a module for MagicMirror.

MMM-JSONStatusChecker will periodically call a URL and display a "true / false" (or "connected / disconnected) status based on the results of a value in a JSON response from the API call.

Multiple instances of the module can be used to call different URLs/APIs using the same background helper. Each instance has it's own configuration and refresh time.

Example:

The AirVPN service provides an API which can be called to check service status and if a user is connected or not from an external source. This module was originally created to periodically verify that a NAS was still connected to the VPN.

2. Execute git clone https://github.com/shbatm/MMM-JSONStatusChecker.
3. Add the module to your MagicMirror's config.js file (see next section).

Using the Module

To use this module, add it to the modules array in the config/config.js file:

modules: [
    ...,
    {
        module: 'MMM-JSONStatusChecker',
        header: 'JSON Status',
        position: 'top_left',
        config: {
                // See Configuration Options below
                }
    },
    ...
]

Note: Multiple instances of this module can be added to the config and the node_helper.js will manage the multiple calls to various locations.

Configuration options

Option	Description
name	Required - The name for this instance of the module. This is used to allow multiple instances of the module with only one node_helper.
apiKey	Optional Your API Key from the service to be used. Will be injected into the url provided.
urlApi	Optional - The URL to call to get the connected status. To inject your API into the URL, add {{APIKEY}} into the URL where the API key goes. Example: https://airvpn.org/api/?service=userinfo&format=json&key={{APIKEY}}
updateInterval	Optional - The interval in ms for updating the information Default: 60000ms (10 minutes)
keyToCheck	Optional - The dot-separated path to the key in the JSON response that will be checked. The JSON Response will be recursively checked for the key. Default: user.connected
keyValue	Optional - The value for which to check the keyToCheck. The module will evaluate if JSONResponse[keyToCheck] === keyValue to determine what status it should show. Default: true.
trueString, falseString	Optional - The values to display if the keyValue is true or false, respectively Default: "VPN Connected" and "VPN Disconnected"
icon	Optional - The Font Awesome icon to use (omit the fa-). Default: plug. Set '' to not show an icon.
trueClass, falseClass	Optional - The CSS classes to add if the keyValue is true or false, respectively. Default: None.
