Wall tablets

A tablet on a wall shows the house all day, often on a weak device. Since 2.13.4 the card has a kiosk mode and a quality profile for it, in the Wall tablet and Rendering sections of the editor.

kiosk: yes
kiosk_tour: 20 # seconds of each view
kiosk_idle: 60 # seconds after a touch
quality: auto

Kiosk mode

kiosk: yes hides the header of the card and all its menus and buttons: the views menu (or its buttons), the levels, the Map menu and the button of the cameras. The boxes, the markers and the icons of the cameras stay, and a tap on an object still runs its action.

Option	Default
kiosk	no	yes: no header, menus or buttons.
kiosk_tour	none	Every so many seconds the camera flies to the next view: the initial view, then each view (zoom_areas) with its level, then the initial view again.
kiosk_idle	60	Seconds after the last touch before the tour goes on from the initial view. Without a tour, the camera goes back to the initial view. 0: never.

A touch on the card (the model, a box, a marker) stops the tour, so that the camera doesn’t fly away while someone looks around. With alarm_view: yes the camera stays on the room of an alarm while it is on, and the tour goes on after. The tour doesn’t run in the preview of the card editor, where the camera is where the editor puts it.

The card hides only its own menus: the header and the sidebar of Home Assistant are hidden by a panel view with an integration such as kiosk-mode from HACS, or by the browser of the tablet (Fully Kiosk Browser, for example).

Quality

The card draws the model as sharp as the screen allows and with all the shadows the GPU takes. A weak tablet then turns the model slowly and gets warm. quality: low asks less of it:

• the canvas at 1 pixel per pixel of the screen, instead of up to 2 (max_pixel_ratio wins when set);
• at most 4 lamps casting a shadow at once, plus the sun (max_shadows wins when set): the first 4 lamps in the order of the entities, or with extralightmode: yes 4 of the lamps that are on;
• a smaller shadow map for the sun: a quarter of the memory, with softer edges.

quality: auto is low on a device that looks weak: 2 GB of memory or less (Chrome and the Android browsers tell it, Safari doesn’t), 2 cores or fewer, or a touch screen with 4 cores or fewer. Elsewhere it is high, so the same dashboard is sharp on a computer and light on the tablet.

Option	Default
quality	high	low or auto.
max_shadows	as many as the GPU takes	Lamps casting a shadow at once, the sun aside. With any quality.
max_pixel_ratio	2, 1 with quality low	The highest resolution, in pixels per CSS pixel.

Other options that help a weak tablet: shadow: no (no shadows at all), log_depth: no (the default), and extralightmode: yes, so that only the lamps that are on cast a shadow.
