Sonoff MINI R2, a reinforced MINI two-way DIY smart switch, redesigned itself to improve safety as well as performance to an optimal level. The old version MINI has an external antenna, but the MINIR2’s antenna is completely hidden in the interior, ensuring you peace of mind when using this device.
Additionally, we colored the S1 and S2 interfaces gray to distinguish them from the other high current input and output interfaces. This helps remind you not to connect strong current to both of these interfaces
Requires a qualified electrician to install
