OptoTutorial 2232: Creating a Weather App with groov and Node-RED (Quick-Start)
2232_OptoTutorial_groov_Node_RED_Weather_App_Quick_Start
With this quick start OptoTutorial, you’ll create a fully-functioning weather app by using groov, Node-RED, and the Weather Underground API. You don’t even need to know groov—this tutorial walks you through the process, step-by-step.
The tutorial’s zip file contains code for a groov page, prebuilt with gadgets to display weather data. It also contains code for Node-RED flows that get, package, and send data from the Weather Underground (wunderground) API to groov.

OptoTutorial: Using the SNAP PAC REST API with Excel
2229_OptoTutorial_SNAP_PAC_API_Excel.zip
A great advantage to getting data from a PAC controller into a Microsoft® Excel® worksheet is that you can use Excel’s features to analyze the data.
This tutorial walks you from the beginning—setting up the Web server in a SNAP PAC controller—all the way through creating an Excel worksheet with Visual Basic® for Applications (VBA) macros that:
• Read and write to input and output points
• Parse JSON text strings
• Check for input and return errors
• Collect data on an automated interval and display it in an Excel chart
