Can you please post all the parts of the config that are related to showing camera feed on a google home device? (so far you’ve just shown the switch, right?)
there is actually nothing more
its indeed a template switch
i am using google cloud nabucasa, so i just expose that switch to google
in google home, instead of a camera, i see a switch that i can turn on/off
ok, i see in RC release notes for 110 release , that we can now configure 2 base urls
internal + external
maybe that helps for the slow camera streams! 
Did the internal_url and external_url addition fix it for anyone? It didn’t here, same “Smart Home Camera” screen-only issue.
