and it uses a program called catt which I can use to cast my Openhab screen to a chromecast device that has a screen. E.G my TV has a chromecast plugged into it.
I can get the Openhab screen to display no problems and it even worked first time I did it BUT how do I get the web UI not to show the side panel (the panel that has the log on thing on it and menus)?
I’m rooting around for the same solution. Suspect you found it. Can you post if you did for future reference? I’ll do it too if I find the answer…
The only way I have found is to cast the screen to the device and then press the small pin icon to remove the side menu.
Then I stop the casting and when it gets cast again it seems to “remember” the setting so it displays full screen.
My screen is a touch screen.
Can you cast it to some other device and then set the screen and then cast it to the device you want to use?
That may work?
Just tested that theory as I have 2 google displays but it looks like the screen is per display.
I set one screen with the menu showing and then stopped the casting and then cast to the other display but it didn’t have the menu showing on the side.
I think I need to install VNC or something, which isn’t really worth the effort for what I’m trying to do at the moment. Maybe I’ll try another kiosk app on this Pi at some point. Thanks for the tips!
