Smart Start process

[georgeinva2004]

This is where my ignorance of ZWave is going to show. I apologize in advance if this is a dumb question.

I successfully integrated the new version of ZWaveJS.NET into my app. I can capture the QR Code on a ZWave device successfully. Unfortunately, when I pass the code to the ProvisionSmartStartNode method, I get an error back saying that the QR Code needs to begin with a "90". The QR Code on the device (Sengled light bulb) seems to match the serial number on the box. Is there a step I'm missing?

Hi @georgeinva2004,

This error is from the driver.
Smart Start QR Codes don't actually have the serial number of the device in them - they contain a large amount of information, but not the serial number to my knowledge.

a Smart Start QR Code will usually have a 5 digit number printed along with it.
below is one from one of my devices - I have changed the Security data inside of it (DSK) - for obvious reasons 😅

Use the below, and you should see it will be accepted (if I haven't messed it up)
900143493001111112222233333444445555566666777770089900100179303072022000881000020000700256

The 5 digit pin (that may also be printed) is the first 5 digit segment. of the 5x8 digit DSK (highlighted below)

900143493001111112222233333444445555566666777770089900100179303072022000881000020000700256.

Its very likely the QR code you're scanning is not a smart Start on, S2 support is needed on the device for Smart Start

Once a QR has been accepted - the device will auto pair the next time it is powered on (and not already attached to a network of course)

I apologize in advance if this is a dumb question.

and don't apologize 😉

A couple of things. Came across this post from Sengled saying that the QR code on the box may have been misprinted, so I used the QR Code on the bulb itself. https://support.sengled.com/hc/en-us/articles/360001982014-I-scanned-the-Element-box-QR-code-and-it-said-it-was-not-a-Sengled-product-What-do-I-do-

The QR Code on the bulb is this(X's added by me to obfuscate the actual code):
. It kinda matches the code in the docs, but not exactly. I don't see anything on the bulb that specifically says it's a "Smart Start compatible device". I'm thinking that this isn't truly a Smart Start device, or I need to adjust the QR Code somehow...

My Thought on it, is that it is not Smart Start capable 😞 - Or they have really!! messed up the QR code 😬
The Smart Start QR codes are numerical only and should contain no special characters and of course start with 90.

A Smart Start QR example is below.
Code blocked numbers are changed for security - as this range is the encryption key (The DSK)

I think I figured it out (and the reason is embarrassing). I took a look at the packaging on the light bulbs and discovered that they were Zigbee not ZWave. So, a very rookie mistake on my part...

[marcus-j-davies]

They both begin with Z - so only a little mistake 😉
