just very basic stuff here but I havent seen one yet, so here I go with a dashboard with sensor data. I just followed this (amazing trick! HOW-TO Store data in Google Sheets directly from RM5) and then shared the image right from the google doc, then I created a new tile with Template as Link and background image with the given URL.
note to the reader
not an NCSA agent here but dont use it for confidential data !
