I’m about to embark on my first integration - I want to add data from (but not control of) my solar thermal heating controller - it’s a RESOL.
It logs the data I want to a text file on an SD card.
I’ve installed a Toshiba wifi SD card, and have that mounted on a windows PC so that I can read it whenever I want.
I used to be able to code & am now embarking on having a go with Groovy.
I figure that I need to create an app (or possibly just a batch file) running once a minute on the windows PC, that reads the text file, extracts the data from the last line, then uses curl to post the data to smartthings.
I then presume I’ll need a custom handler / smartapp to grab the data and handle/display it.
Is there anything out there already that I might use as a starting point for this, or something similar that I can use to get the basics of getting data / info in from the outside world.
Thanks in advance!
