The Sonoff NSPanel (EU) wall box is a practical and smart solution for controlling your smart home system. The wall box has room for thicker cables and larger USB plugs, which makes installation easier. This version has deeper channels for cable routing and a larger opening on the back that allows a regular sized USB plug to be fed through without having to damage the back of the adapter. The wall box also has mounting holes far from the cable routing channels, which provides a cleaner installation.
