Easy Dashboard Graphing issue

Two issues:

  1. EZ Dashboards does not offer a graph tile type option for the Zen 16 relays. The only options for the Zen 16 relays are Switch and Light. I'd like to use a bar chart to visulize what how often and when a particular device is on vs off over time. I'm guessing Hubitat needs to add the graph functionality to the relay type device, but it is just a guess...
  2. EZ Dashboards offers a graph tile type for plug in dimmers. I selected such for an older Jasco device. When I clicked the save button the entire dashboard disappeared. I've refreshed, gone into the EZ dash add/delete devices and saved, but no matter what I do, I get a blank page instead of this dashboard. What should I do?
    ETA: I deleted the specific device tile on which I had selected graph from EZ Dashboards, then saved and then the dashboard tiles reappear. However, the tiles are all rearranged and the helper tiles are all renamed to repeat the name of one of them....and these duplicate helper tiles are uneditable, so still don't know what to do short of rebuilding this particular EZ Dash in its entirety
