littlebits-cloud-http lightweight wrapper for littleBits Cloud HTTP API
In a function node (triggered by Blynk-ws read event node),
// "access_token" and "device_id" are acquired from littlebit cloudcontrol setting page
var api = require('littlebits-cloud-http')
.defaults({ access_token: '**jfslf478jliwt9s**' });
api.output({device_id: '**slkjfie**', percent: 50, duration_ms: 5000 });
Create a new subscription for device_id.
// "access_token" and "device_id" are acquired from littlebit cloudcontrol setting page
var api = require('littlebits-cloud-http')
.defaults({ access_token: '**jfslf478jliwt9s**' });
api.subscribe( {
subscriber_id : 'https://immense-garden-*****.herokuapp.com/bits',
publisher_id : '**slkjfie**',
publisher_events : [ 'amplitude' ]
});
NOTE Cloud Control and littlebits Invent App worked as advertised. However, the sub/pub model doesn't ( littlebits/cloud-client-api-http has no updates over 3 years.) I didn't find any suitable working example yet. subscriber_id was assgined with the public URL (Node/Express on Heroku Platform) but Express /bits POST handler received no request.
