The devolo Magic 1 WiFi, including the Mini Starter Kit, uses Powerline technology to transmit data via the electrical wiring in your home. This technology is designed to work even when the adapters are connected to sockets in different parts of the house, including through electrical panels.

In general, electrical panels should not interrupt the Powerline signal, as the G.hn technology used by devolo operates on the low and medium frequencies of electrical cables, allowing reliable transmission through most domestic electrical installations.

However, it is important to note that specific conditions, such as particular switches or fuses, could potentially affect signal quality. But in most cases, the devolo Magic 1 WiFi system should work fine even with an electrical panel between the two sockets.
