SunSprite Calendar View web service
Install on a local server (adjust the IP address in the Template node under "A web service") and run this to display a calendar view of your SunSprite-based light exposure.
This is an example for several things:
- shows how to deal with web forms via Node-RED.
- shows how to deal with the lack of a http response object (not copied across like most other msg properties).
- shows how to interact with the Kinvey API (a commercial PaaS MongoDB)
- shows to dump data into the Google Charts API to plot the graph.
