The Shelly Wall Display XL builds on the concepts of the Wall Display and Wall Display X2 by offering an option for centralised touch-screen smart control; the Wall Display XL features embedded relays able to control appliances up to 1500W as well as integrated Bluetooth and WiFi modules to communicate with other Shelly devices, and can be installed in a standard EU switch box. The Wall Display XL makes a number of improvements on its predecessors; it features a larger screen with an HD colour display, and includes integrated 2W high-quality stereo speakers. The Wall Display XL also includes four physical buttons that can be customised to trigger anything from a single relay to a coordinated scene involving multiple relays. The Wall Display XL also includes built-in proximity and brightness sensors, and is capable of monitoring the power draw of any Shelly relay to which it's connected.
