Frequently asked questions

• Can the two lights run separately, each on its own schedule?

  Yes — that is the point of the Duo: outputs L1 and L2 are fully independent. Each line gets its own schedules, scenes and voice commands, while the wall keys keep controlling their own circuits.
• How much load can each channel and the whole module take?

  Up to 10 A per channel and 16 A combined, rated for resistive loads. Keep headroom for LED fixtures with drivers, and fit a 16 A MCB or RCBO ahead of the module.
• Will my existing wall keys work, and how do I set their type?

  Rocker (latching), momentary and SPDT switches are all supported. The factory default is rocker; to change it, press the on-case button three times in a row — the LED blinks three times to confirm.
• What does Detach Relay mode do and where is it set?

  It decouples the key from the relay: a press no longer switches the load but fires a scene instead — handy when smart bulbs that need constant power sit on the line. It is configured in eWeLink only; Matter ecosystems do not expose it.
• What has to be present in the wall box before installation?

  Live, neutral and both load lines to the fixtures. In older buildings the neutral often does not reach the switch box — then it must be pulled in, or the module goes at the fixture instead. S1/S2 terminals take live only; never neutral or ground. Box depth: at least 60 mm.
• Do I need a hub to add it to my smart home?

  Not for eWeLink — the module talks straight over 2.4 GHz Wi-Fi. Matter ecosystems need their platform controller: a HomePod or Apple TV for Apple Home, a Nest speaker for Google Home, a compatible Echo for Alexa, the Matter integration for Home Assistant.
• Why one MINI-2GS instead of two single-channel MINIR4M units?

  Space and wiring: one body in the box instead of two, a single live and neutral feed, and one Wi-Fi client on the network instead of two. For a single line the MINIR4M is enough; the wall-panel alternative with its own keys is the MINI-2GS-E.
