Some time back, I created a couple of pistons for writing to and reading from google sheets. As a simple use case, below is an example I created using these two scripts for monitoring rainfall in my area. If you want to implement this, first create your google sheet and scripts as described art the links above. The pistons below assume that is complete and the URLs for the two scripts are stores in global variables @URLWriteScript and @URLReadScript. Both of these are declared as strings. These pistons also take advantage of another global variable I have @@myLocationName. This is a string with the name of my city. You can chose to hard code this or use your own google sheet tab name. Just be sure the tab exists in your google sheet document.

Now I can look into my log and see/plot the history of rainfall in my area and the second piston will tell me if I should turn off the sprinkler system.
