LELLKI WP35 Matter Power Strip

Device

LELLKI WP35 Matter Power Strip

I would like to request official support for the LELLKI WP35 in the SmartThings matter-switch driver.

Matter identification

• Vendor ID: 0x1400 (5120)

• Product ID: 0x03EA (1002)

• Tested firmware: 1.10

• Outputs: 4 AC outlets + 1 USB output

Verified Matter endpoint layout

The device exposes five OnOff server endpoints:

Matter endpoint | Physical output | Suggested SmartThings component -- | -- | -- 1 | Outlet 1 | main 2 | Outlet 2 | switch2 3 | Outlet 3 | switch3 4 | Outlet 4 | switch4 5 | USB | switch5

I have verified on a real SmartThings Hub that On/Off reads and commands work correctly on endpoints 1-5, and that the corresponding component states can be updated independently.

Suggested fingerprint

A fingerprint entry could identify the device as follows:

matterManufacturer:
  - id: "5120/1002"
    deviceLabel: LELLKI WP35
    vendorId: 0x1400
    productId: 0x03EA
    deviceProfileName: <supported 5-component switch profile>

I noticed that drivers/SmartThings/matter-switch/profiles/switch-5.yml already has the same main, switch2, switch3, switch4, switch5 component layout, but that profile is explicitly marked:

Deprecated: do not use this profile for device fingerprinting.

Because of that, I am not proposing that the deprecated switch-5 profile be used directly.

It would be helpful if the maintainers could advise whether the WP35 should use an existing supported dynamic profiling path or whether a supported five-component switch/power-strip profile should be added.

Current community driver / reference implementation

I created and tested a dedicated Edge Driver that presents the WP35 as one SmartThings device with five switch components:

https://github.com/leathersocks/lellki-wp35-edge-driver

Current mapping used by that driver:

LELLKI WP35
├─ main    → Endpoint 1 → Outlet 1
├─ switch2 → Endpoint 2 → Outlet 2
├─ switch3 → Endpoint 3 → Outlet 3
├─ switch4 → Endpoint 4 → Outlet 4
└─ switch5 → Endpoint 5 → USB

The implementation has been runtime-tested on a SmartThings Hub.

Refresh successfully reads the OnOff state from endpoints 1-5, and independent On/Off commands have returned successful Matter command responses with the corresponding OnOff state reports.

Requested change

Please consider adding the LELLKI WP35 Vendor/Product fingerprint to:

drivers/SmartThings/matter-switch/fingerprints.yml

together with an appropriate supported profile/profiling configuration so the device can appear as a single multi-component SmartThings device rather than requiring a separate community driver.

I can provide additional SmartThings Edge Driver logcat output or device endpoint information if needed.

Thank you.
