I should point out that I’m willing to add code. I looked at the instructions at the OLA “adding sensors” page https://github.com/sparkfun/OpenLog_Art … SENSORS.md; however, the repo for making updates has no place for sensor library to go – at least I didn’t find one.
The sensor has an Arduino library for the AS7331 https://github.com/sparkfun/SparkFun_AS … no_Library
The OLA is a much better solution than the one I made with an Arduino UNO and a data logger shield back in 2012 or so.
