Shelly Wall Display and BLU H&T
Shelly Wall Display is a wall-mounted smart home control panel with a 4-inch touch-sensitive colour display, designed to provide centralised room control, monitoring, and automation. It includes an integrated 5 A relay for appliance control, room-level power consumption monitoring, and built-in temperature, humidity, and light sensors to support advanced automations.
When paired with the Shelly BLU H&T sensor, the Wall Display can function as a room thermostat, enabling temperature-based control scenarios. The device connects via Wi-Fi with no hub required and also supports Bluetooth. It is intended for installation in a wall box and is suitable for residential, commercial, and institutional environments where a fixed control interface is preferred. A neutral wire is required for relay operation.
