Unable to Add Any New Device

A few weeks ago, I noticed that I no longer had control of a Leviton dimmer switch. I tried excluding the device and re-adding it, but that didn’t work. Oddly, I was able to “successfully” exclude the device multiple times through the SmartThings app (Android; have tried multiple devices). Assuming the device was dead, I ordered a replacement. Upon installing the replacement, I experienced the same issue when trying to add it to my network (simply no device is detected). In an effort to troubleshoot, I removed a known working device from the network (GE Dimmer). After removing the device, I am now unable to re-add it. I power cycled the hub and even moved it as close as possible to the switches I’m trying to include. I have also watched the logs for the hub when trying to add devices, but nothing shows up. I am at a loss and would really prefer to avoid factory resetting the hub.

are you using any custom device handlers for dimmers? if yes, login to IDE and open the device handlers and publish for me again. then exclude and try to add your devices

I was just using the generic “Dimmer Switch” device handler for both of the switches I’ve “lost” now. I will double check that and republish anything that might be related. Thanks for that suggestion. I also got a reply from support with some instructions for a power cycle (3-5 minutes!) and exclusion to try.

I had a handful of device handlers (none of which were related to the devices in question) and a smart app that was related to both devices. I went ahead and re-published all of the things, but I’m still unable to add devices. I also followed the support instructions which were just a 3-5 minute power cycle followed by a general device exclusion. One interesting note is that every time I perform the general device exclusion on these devices, I get a success message even though at this point, neither is part of a network.

Looking at the system logs, you are definitely hitting the known issue that jkp is referencing. Make sure to republish or comment out the fingerprint of all matching device handlers as you may have more than one that matches.

Also, that is expected behavior. Any Z-Wave controller can exclude any Z-Wave device.

I tried republishing again with all device handlers that have a status of “Published” (I have one that is Unpublished, and I’m not sure where I left off with whatever project that was). I then did a general exclusion (which succeeded) and tried to add the device back with the same behavior. Full disclosure: the devices in question are just standard Z-Wave dimmer switches (one is Leviton, one is GE), and none of my custom device handlers are for a dimmer switch. On another note, the brand new switch I tried adding yesterday was a Homeseer that had never been included in my network.

I understand that any controller can exclude any device, but it was curious to me that a device would return success even if it wasn’t included previously. If that’s how the protocol works, I’m sure the Z-wave alliance had a reason, and thanks for the info.

*Edited to add info about the Homeseer switch

Thanks for the info. I should have checked sooner but the issue is that your hub’s Suc ID is 00 instead of the expected 01. So your hub likely thinks it is a secondary controller.

I’ll flag this for a Z-Wave engineer to see if we can resolve it.

Brad got me sorted out by correcting the ID issue. Thanks for the help and all of the suggestions.
