Hi all,
I thought I would share something I figured out when attempting to add a camera stream to a picture_elements card when the view is in panel mode.
It turns out that you can’t add a picture-entity card into a picture_elements card - you can only use an image element. The problem there is that the image element is mostly a static image and not a live viewing of your camera stream.
As a little work around to have a LIVE stream from your camera, I found you can use a custom card called layout-card (thanks @thomasloven) and with this card, you can insert a picture-entity card for your live camera stream.
- type: 'custom:layout-card'
column_width: 100%
style:
left: 80.5%
top: 42%
width: 33%
cards:
- type: picture-entity
entity: camera.indy_s_room
camera_view: live
show_name: false
show_state: false
↑ This gives me the following output: ↓
SIDE NOTE: If you are using a Windows tablet/PC and you want Windows to turn the screen off after X minutes you will have a few issues as the browser detects the video is playing so it prevents Windows from going to sleep…
Not sure if this affects Android/IOS as well.
Let me know if anyone needs any assistance with solving this issue
