But if I use the HomeAssistant .. in this case I would prefer an cheap Xiaomi Smartphone to use the HomeAssistant App in my Szenario .. and it´s another device consuming power.
In my case it´s in an CamperVan and less power consumtion would be nice and Shelly has already everything but not in the Wall Display 
The only way is to use a button and rename the useless button to show up on the screen like "Volume 15 L". But this is less beautiful and there isn´t also a solution for controlling something.
Hi, I tried the Shelly Wall Display and there are many good things already implemented. But there are many things still unsolved.
One thing is the missing virtual component support for text and other useful types.
I have some information I want to display there from other devices by REST or MQTT. As simple text would be a bare minimum to use ist in my Camper.
Is there a way around or is it not possible at the moment and also not in the near future?
