Failure including Leviton fan controller via SmartStart QR code

kccricket · December 2, 2022, 10:13pm

Controller: Zooz ZST10-700 v7.17.2
Integration: Z-Wave JS 0.1.74 addon
Home Assistant: 2022.11.4

I have a Leviton ZW4SF-1BW 4-speed fan controller that includes an identical Smart Start QR code on both the packaging and switch body. If I use the Home Assistant companion app (2022.10.1) and scan either QR code to include the switch into my Z-Wave network, the QR code scanner displays an error:

Z-Wave error 1406: Invalid QR code: contains invalid characters (ZW1406)

If I read the QR code with a different app and parse it manually, it appears to be well-formatted when compared to the specification. Is HA not supporting Smart Start codes currently?

Their QR codes are broken. Check the scanned text code again and you will find a trailing white space character. I would complain to their support, after all they are part of the “Works with Home Assistant” program. It’s an easy fix for the Z-Wave driver, but it’s annoying it should have to workaround such an issue.

Receiving QR code Error when trying to add Leviton Outlet (ZW15R)

question investigating

Good afternoon, I'm trying to add a Leviton Decora Smart Outlet (ZW15R) to my Z…-wave network. This is a 700 series Zwave plus outlet, supposedly with S2 support. When I attempted to add it to my mesh through scanning the QR code, I received the following error: "Error while calling api parseQRCodeString: contains invalid characters (ZW1406). I purchased 3 of these switches, and I've tried it on two so far, and zero luck. I tried to add them the old fashioned way, by putting my Z-wave network into inclusion mode, and then held the inclusion button for 7 seconds, then pressed it once more after the light started flashing amber, to put it into inclusion mode per the manual, and it was found and recognized by HA, however, it did not prompt me for a PIN for the S2 security. I've attempted to contact Leviton nad I was met with perhaps the dumbest Tier 1 I've ever spoken to, and then the rudest Tier 2 who didn't understand or care about the QR code issue. He said, "well t's included, so that's all I can help you with." So my questions are: 1) is this QR code a problem with Z-wave-js-ui, or with the manufacturer? 2) Is there a way to get the prompt for the PIN on this device?

Trim SmartStart QR codes

. I noticed however, that the QR cod text copied from the camera included a tra…iling space after the last digit. When I backspaced, the QR code was accepted. ![IMG_0040](https://user-images.githubusercontent.com/13274413/202519522-ab3209e0-be43-460c-903a-18e3cf26c336.PNG) I checked the other two outlets, and they all had the same trailing spaces. The only thing I could say that the app could do is do a sanity check when it scans the QR code with the camera, look for trailing spaces, and delete them. I would think that would avoid this problem in the future. __Originally posted by @tamorgen in https://github.com/zwave-js/zwave-js-ui/issues/2766#issuecomment-1318990038__

That’ll do it. Thanks. I checked the HA issues and the forum here, but didn’t think to check the zwave-js-ui repository for issues. That’s a lot of places to check…

I can’t figure out how to include my newly-installed Leviton ZW4SF switch. When I use the Home Assistant Zwave JS UI “inclusion” mode (and put the switch in inclusion mode, obviously), Home Assistant either never ‘finds’ the switch, or else it doesn’t like it - there is no error message. I attempted several times (including reboots), and tried specifying S2, S0, and no encryption. Results were always the same.

A couple of days ago I was able to successfully include a different Leviton switch using the same method, and it worked fine.

I’ve never been able to use the QR code to add a Leviton device, so admittedly I never tried that method. If there is a workaround, I am very OK with that.

Any help would be appreciated. Thanks.
