WiFi Temperature Monitor - Part II

Since writing the first WiFi temperature monitor post, I’ve implemented retrieving temperature values on a schedule, to generate a real-time dashboard. I came across this Gadgets Apps Hacks Post, which utilizes Google Apps Script’s ability to connect to External APIs and record stock ticker values over time in Google Sheets. The method I used in the first part to write the temperature sensor value in a Sheet is more suited for a single import of a larger data set in JSON format. There is also a tutorial from Particle that uses IFTTT to log the data in a Sheet.

I’ll use WeatherUnderground for the outside temperature and Nest for a comparison of inside temperature from another device.
