Problem adding Sunricher SRP-ZV9105-75CC (Z-Wave Dimmable LED Driver)

Devices

Hi everyone,

I’m trying to add a Sunricher SRP-ZV9105-75CC Z-Wave Dimmable LED Driver to my Homey (EU frequency, 868.42 MHz), but I always get the same error:

“Unable to connect — Something went wrong while adding the device.”

I’ve tried multiple approaches:

  • Using the Sunricher app, ROBB Smarrt app, easylighting app and Generic Z-Wave device

  • Factory reset of the device before each attempt

  • Adding both secure (S0 / S2) and non-secure

  • Creating my own custom app using the correct manufacturer and product IDs

  • Even forcing "secure": [] to disable security completely

In every case, Homey shows “Unable to connect” (sometimes request_timeout) and the app log shows no activity — meaning the pairing never actually starts communication.

What I’ve verified

Using Silicon Labs PC Controller (Simplicity Studio):

  • The device includes successfully and responds to commands normally.

  • Here’s the information from the Z-Wave log:

Manufacturer ID: 0x0330  (816)
Product Type ID: 0x0200  (512)
Product ID: 0xD002  (53250)
Z-Wave Plus Version: 2
Role Type: Always On Slave (AOS)
Node Type: Z-Wave Plus Node

So my driver.compose.json looks like this:

"zwave": {
  "manufacturerId": [816],
  "productTypeId": [512],
  "productId": [53250],
  "secure": ["S0", "S2_UNAUTHENTICATED"]
}

Still, Homey always fails with a timeout before reaching the onMeshInit() in the device driver.

My suspicion

It looks like Homey can’t complete the secure inclusion (S2 negotiation), or the product ID is not matching internally.
Interestingly, the same device includes and works fine through the Z-Wave PC Controller, so the hardware itself is okay.

What I’m asking

Has anyone managed to include Sunricher SRP-ZV9105-75CC or a similar Z-Wave dimmable driver with Homey?
Is there any known issue with S2_UNAUTHENTICATED negotiation or Z-Wave inclusion timing on these devices?
Would forcing Homey to include non-secure only be possible through the app manifest?

Thanks in advance for any help — I’ve spent quite a few hours debugging this one and would really appreciate any insight.
