I have a really smoothly running OH2 installation and would like to store some charts on a routine/recurring basis - i.e. every hour.
My intention is to have the chart images sent through FTP to an external server where I host a homepage. This way, I can i.e. expose my temperature readings to friends and family without needing to have them access my LAN or the OH Cloud service.
How do I do this ? (saving chart images)
