Great project. I recently bought an Amazon Fire 7 (7th gen). Just trying a few things out for the time being. HA front end (HASS) loads fine in Chrome, and I am able to view my floorplan, etc.

I installed WallPanel but then my floorplan no longer displays. No idea what the difference is between Chrome and the browser engines within WallPanel, as far as loading the floorplan goes. Anyone else tried getting the floorplan working with WallPanel?
