Hi everyone 
I’d like to share my Homey app for the Shelly Wall Display — a touch screen device that can now serve as a full smart home control panel, powered entirely by your Homey.
What is this app?
The Shelly Wall Display Dashboard runs a local HTTP server directly on your Homey. The Shelly Wall Display connects to it as if it were a Home Assistant instance — while all device data and control come exclusively from Homey. No cloud, no external service, no extra hardware required.
The dashboard also works in any regular browser (Chrome, Safari, Firefox) — just open the URL on any device on your local network.
Install from the Homey App Store (LIVE):

Tap any speaker or media player tile to open a full-screen 480×480 px media control panel:

Energy Dashboard
A built-in energy view with two tabs:
Live — animated flow diagram showing solar panels, power grid, home consumption and battery storage, connected with travelling dots that indicate direction and power level. Minimum size 480×480 px on large screens so the layout always has breathing room.
Devices — individual device cards with real-time watt readings for each solar, grid, battery and EV charger device. Devices marked as “Exclude from Energy” in Homey are automatically hidden.
7 Days — bar chart of daily solar production and grid import over the past week.
Options: invert battery sign (for systems that report positive power when discharging, e.g. GoodWe SMILE, some Fronius inverters).

Tap any thermostat tile to open a control panel:
-
Current and target temperature
