Imagine a beautiful, high-quality wall switch that perfectly complements your interior design, but it isn't wired into your Plejd smart lighting system. The Plejd EXT-01 solves this by turning any existing switch or push button into a wireless trigger for your Plejd devices. It connects up to two potential-free contacts and communicates over Plejd's Bluetooth Mesh network, all from a compact unit that hides behind the switch plate. Powered by a CR2450 battery with up to 10 years of life, it requires no mains wiring and no electrician.
