Moved my EmonSD over to an APU4 and EmonCMS to have a bit more horsepower. In this process I am going through and cleaning up some things. One thing I was starting to think about was trimming old feed data that is >5 years. Was thinking maybe a cron job for it might work, but wasn’t sure if time could be triggered outside of the Emon interface. I had a cron job for backup which worked well before.
Edit - changed topic name to avoid confusion with the SSD function
