Emoncms on pi, power down external drive

[boelle (Bo Herrmannsen)]

it seems that this post is my best bet for moving things to hdd

EmonSD save data to an external HDD/SDD instead of SD

Hi, is there a way to change the location of EmonPI SQL database? I found some info in this thread that suggests to use the script /var/www/emoncms/scripts/usb_hdd/usb_hdd, unfortunally seems that this script just moves root partition to an external hdd and database is still stored in the SD card. Any suggestions? Thanks

or are there better methods?
