I posted this on Discord and people seemed to show interest. Here is the SVG and link to my repo to get an animated Ecobee thermostat on your floorplan, like so:
Note that I have 2 floors in my home, each with an ecobee.
The link to my template is here. There is a thin white box around where the weather icon should appear, this is to make it easier to see in Inkscape only. You should put the stroke-paint to none in your final version on the floorplan.
CSS is here.
Animated weather is credited to @CCOSTAN (as is much of my floorplan success) and is shown here.
Enjoy!
