Local and Remote JSON data to Justgage Gauges.....
Posted: Sat Jun 24, 2017 8:35 amThe displaying of real data from local & remote ESP8266 sensors using very simple CSS/JS/HTML, with CORS (Cross Origin Resource Sharing).
The data is being presented via a client.print() but easily adapted for server.streamFile().
The required Justgage files should be downloaded and compressed with GZIP for uploading to the SPIFFS to save space. Only the 3 files declared in the webpages need to uploaded to SPIFFS.
https://github.com/toorshia/justgage
The links in the files are actively presenting data, so the Webpages will work without editing if you have downloaded the files from the Github.....
The Sketch snippet presentation of the JSON Data...(Not using JSON Library as it is too Slow)......
Data here from ESP8266 with DHT22....
The Webpage for the snippet above presenting DHT22 data.
This Webpage is for a WH1080 Weather-station to be hosted either from SPIFFS or elsewhere........
The Webpage Data is from an ESP8266 relay that is pulling the data from my weather-station.......
