I'm researching how to create a file of attic temperature history.
I'd like to set a variable each hour of the temp of the attic: Attic01 at 1am, Attic02 at 2am, etc. at the end of the day (23:59), write a history record to a file with the variables and the date.
Is there a similar WebCore piston/app I could use for an example?
You could use the graph function of webcore to track attic temp.
Below is my graph that shows temp, humidity and when the attic exhaust fan goes on and off.

Another option would be using the Quick Chart app.

Not worried about charting, I asking how to capture the information to be charted.
How did you capture the information and where did you store it to be charted?
Well you can use webcore's long term storage capability, also under the graphing function of webcore. It will create a text file on your hub that will contain the sensor data for up to several years.
Below is an example of the format. "v" is the value, "t" is the epoch time the data was captured.
"v":"118.9","t":1692464401100},

You can also use InfluxDB Logger to write to a local DB on a always on computer or a free InfluxDB CloudDB

Quick Chart will actually automate the saving of the temperature data to a text file on your hub accessible by File Manager, as well as generate a graph/chart for you.

That's exactly what I was looking for and more!
Thank you
