Shelly BLU Wall Switch 4 - Stand-Alone _MAKE_COMP_OTHER Supports Packet Broadcast Control ChannelThe Shelly BLU Wall Switch 4 is a smart four button Bluetooth control interface. This is the standalone version, intended to be used as a standalone remote control without affixing it to a wall (but feel free to get creative with mounting options!). The switch connects to other Shelly devices on the network through BLE (Bluetooth) technology and contains four buttons, each of which supports multi click (single, double, triple and long press clicks)
