Sonoff ZBBridge-U Zigbee Bridge Ultra gateway with Matter bridge and Ethernet

Via the built-in Matter bridge, Zigbee sensors and relays show up in Apple Home, Google Home, Alexa and SmartThings; Ethernet RJ45 or 2.4 GHz Wi-Fi, up to 256 sub-devices.

When the enemy is dust — traffic outside, a wood stove, fresh renovation — this AirGuard is the one: SAWF-07P reads PM2.5/PM10 every 2 seconds and alerts by light, sound and push.

With an IC behind every one of its 150 LEDs, the Sonoff L3 Pro shows several colours at once and runs chasing gradients along all 5 metres — the 5V adapter is sold separately.

Evenings at a soft 20% and mornings at full power happen behind your existing switch — the MINI-DIM hides in the wall box and keeps the wall button working.

One stop by the front door switches off the whole exit route — three independent channels drive the hallway, kitchen and bathroom lights from a single 3-gang plate.

To guests it is just a wall switch — the key travels with the same mechanical click they expect, no touch glass or screens, while schedules and voice control work quietly inside.

A glance at the relay tells you watts, volts, amps and total kWh on its built-in LCD — no phone required, with six months of hourly history kept in eWeLink.

Sonoff's screen sensor enters a new generation: the AirGuard TH fits daily highs, lows and a second sensor's readings on its 3.6-inch LCD, and Proximity mode needs no hub at all.

Sonoff moved its strip line from the L2's 12V brick to USB Type-C power in the L3 — no adapter ships in the box, so plan on your own 5V/2A charger or a power bank.

POW Origin turns electricity-bill guesswork into hourly kilowatt-hour records — a week of eWeLink charts shows which appliance leads, with six months of history kept.

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.

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.
