Sonoff DUALR3 Wi-Fi 2-gang smart relay switch with power metering

See what each of two loads really draws: the DUALR3 meters voltage, current, power and accumulated kWh independently per 10 A channel, with overload cut-off.

Sonoff MINIR4 Extreme Wi-Fi smart switch relay module 10 A

Lighting a whole flat takes a relay per light point, so unit price decides: the Wi-Fi MINIR4 Extreme keeps 10 A and Detach Relay while costing less than its Matter sibling.

Switch a boiler or heater from your phone and watch its real power draw: Smart Plug 2 meters consumption live and handles loads up to 3680 W.

The extra money over the white B02-BL buys exactly one thing — a 16-million-colour palette on top of the same 9 W, 806 lm tunable 2700–6500 K white.

When an ordinary bulb burns out, screw this one into the same E27 socket and the room gains scheduled warm-to-cool white, a gentle wake-up light and phone control — no hub needed.
