..... without using the browser back button.
Background : I created a link to my camera stream which works fine (I got tired of seeing a 1 second update via the normal image tile) but now that I've got my nice 20fps video showing how do I revert back to the dashboard without using browser controls?
I'm casting to a Nest hub so everything has to be done on the dashboard itself. I can't create a link back, or can I?
Create a tile on the dashboard and choose the type "Dashboard link" then choose the dashboard you want to link to.
Click the small + sign in the top right corner of your dashboard.
Select the Dashboard Link as your type.
Select the dashboard you want to link to.
The link to camera stream (say 192.x.x.x:xxxx) pops the stream into its own dashboard with no apparent way back.
If I create a new dashboard instead how do I show the live stream in that dashboard? Do I use iframes?
You cannot use 20fps with dashboard they do not refresh that fast (would crush your hub). You have to use 1 sec. If you have PTX you can add preset using my post here.
EDIT: you could possibly do it in an iframe window, but not 100% sure on that.
That's what I'm doing at the moment. I wanted to see a stream with more that 1fps when I click on the image tile so I was going to overlay a link to the mjpeg stream on the image tile.
Which works but as I said I can't get back to the original dashboard.
PS : I'm not wanting to have a permanent 20fps video (or even 10fps) on the dashboard (the stream bandwidth would be too much), just to have the ability to view it when I need to. No big deal if it isn't possible 
EDIT: Just tried this Putting live video from (almost) any web/ip camera into your dashboard. Seems to work fine for just on demand viewing.
