I am trying to repair my VZW dimmers using smartstart to take advantage of ZW Long Range. When I use my Hubitat Zwave tools to scan the QR code, I get an error that says the QR code is invalid. I use this method to pair my Zooz devices. Am I using the QR code wrong? Is there a different way to pair for ZW LR?
You mentioned re-pairing… Is the switch confirmed as successfully excluded from your mesh?
I’ve been using Jeff Page’s Smart Start app to manage my LR pairings, but I don’t have any Reds.
In the second post of that link, he has basic Smart Start pairing instructions.
Yes, the switch is removed from the ZWave radio, no longer included. I use the Smart Start app to confirm settings and inclusion, but I use the Zwave tools tab in Hubitat to read the QR code.
The QR code on my switch claims the code is invalid.
Instead of using the built in Zwave tool, I tried scanning the QR code and pasting the data into the Smart Start App.
Scanning the QR code gives me this string:
Z:943469FFFE05C61F$I:AE4ECD1E8DFD3E0649EB689F8D0226BB6917
When I paste this string into the DSK field in smartstart manager, it greys out the SAVE button, indicating this is not a valid entry. Do I need to trim the string or reformat it?
The QR code contains the device’s DSK. In addition to the QR code on the switch, a second copy is on a piece of paper that was included with the switch, so try that one.
Also, if what you are doing allows you to enter the DSK manually, the DSK is printed on the piece of paper that shipped with the switch. If you don’t have that paper and can enter the key manually, so can obtain the DSK by adding it the the Zwave PC controller on a PC with a Zwave dongle.
I don’t have any of the papers or packaging that came with my switch, so those aren’t options.
You said, the QR code contains the device’s DSK. When I scanned the QR code with my phone, it gave me the string above. The string above is the DSK?
It does not appear to be in the correct format, or has addition characters?
I am prompted to enter a DSK with this format:
ppppp-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx
this is the raw text from the QR code:
Z:943469FFFE05C61F$I:AE4ECD1E8DFD3E0649EB689F8D0226BB6917
I’ve never decoded a DSK from the QR code, so I can only get you part of the way.
The format you posted is correct. A DSK is 8 sets of 5 digits.
DSKs are coded in hex. 2 bytes are used to represent each 5 digit value.
What I am unsure of is if you decode what you posted 2 bytes at a time, you get more than 8 sets of digits. There are 4 in the Z and 9 in the I, and I don’t know what Z and I refer to.
I converted the two bytes pairs as follows. Did this quickly so you may wish to double-check my calculations. Maybe start with the Z and use some of the I, or ignore the Z, start with the I and ignore the last 2 bytes. I just don’t know exactly how this is coded. I’m guessing they’ll be in sequence but I’m not sure where to start.
Hopefully someone can add to this.

Bry, thank you for going out of your way in helping me decode the “DSK”. I quoted “DSK” because it turned out that wasn’t the DSK. I had the wrong driver applied to that switch, and it was actually a Blue series Zigbee switch. I didn’t realize until hours later when I gave up trying to decode it and pulled the switch out of the wall, installing a brand new Red series I had on hand.
The new Red series, along with the rest of my existing Red series pair right up using the QR code on the front of the switch. I’m also making a spreadsheet to keep all the DSK’s in case these QR codes get damaged in the future.

You’re not alone… I just made the move from SmartThings to HA and went around exluding and adding my zwave switches. I got to this one switch in my kitchen that I couldn’t for the life of me get it to pair. I went online to search for what to do next and found this post… “You’ve got to be kidding me”. I pulled the switch off the wall… sure enough, “Zigbee”.
