Gledopto GL-SD-001 Zigbee 3.0 Triac trailing-edge dimmer for 230V lamps

The wireless link or network the device uses. Wi-Fi connects straight to the router; Zigbee, Thread and Bluetooth Mesh work through a hub or gateway.

Whether the device needs a separate hub, gateway or coordinator to work in a smart home. If so, it is sold separately unless stated otherwise.

How the device connects to Home Assistant: a built-in integration, a Zigbee coordinator, Matter or the maker’s cloud integration.

Whether the device keeps working over the local network or through a hub when the internet is down. Cloud features (remote access, voice assistants) need the internet.

The maker’s app used to set up and control the device.

The stated radio range, usually in open space. Walls and floors cut it noticeably.

Total LED lamp wattage per channel that the maker allows. Add up the watts of all lamps on that circuit and compare; for dimmers only dimmable lamps count. If the maker gives the figure in VA or as a total for all channels, the note says so.

Power of incandescent lamps, 230 V halogen lamps, heaters and other resistive loads per channel. For LEDs, motors and power supplies the permitted power is lower — see the separate figures.

The highest current one channel handles with a resistive load. For LED lamps check the separate “LED load” figure, which is usually noticeably lower.

The supply voltage (and current, if stated) as the maker gives it. It must match your mains or adapter.

Whether the wall box needs a neutral wire. Older wiring often brings only the live wire to the switch; then pick a model that works without N.

How and where it is installed: in a wall box, on a wall or ceiling, on a DIN rail, on a table or in a socket.

The device’s size in millimetres as the maker states it. Check that it fits the wall box, niche or shelf.

Protection against dust (first digit) and water (second). IP20 is for dry rooms only, IP44 resists splashes, IP65 and up handle water jets and outdoor use.

Standards and certifications the maker lists for this model (for example CE, RoHS, Zigbee 3.0, Matter).

How the dimmer cuts the mains sine wave. Trailing-edge dimming usually runs dimmable LED lamps more quietly and with less flicker; leading-edge is designed for incandescent lamps and conventional transformers. Universal models pick the mode themselves or let you switch it in settings.

Whether you can set the lowest and highest brightness to suit your lamps. This helps remove flicker or buzzing of LED lamps at low brightness and avoids the dead part of the scale where the lamp no longer lights.

Whether you can keep an ordinary wall switch or push button and wire it to the module, so the light works from both the switch and the app. Shows which switch types are supported; on dimmers a momentary button usually also adjusts brightness when held.

How many separate loads (light circuits, appliances, motors) the device controls independently.

The air temperature range the device is rated for. The lower limit matters outdoors, on balconies and in unheated rooms.

The warranty period the maker states. Confirm warranty terms in Moldova with the seller.
