Zwave - have both ZW and ZY devices, and finding a Zwave device

[ctviggen1]

I upgraded a while back from ISY 994.  I have both ZW and ZY devices.  Should I have both?  If so, what's the difference between them?

I bought a bunch of plug-in Zwave devices to put near one of my doors with a Zwave lock.  Normally, I name my devices so I can find them, but since I bought so many Zwave plug in devices, I didn't name them. So, I have ZW 016, 017, 018, 019, and ZY 002, 004, 005, 008, 012...

One of these is a dimmer that is connected to a lamp but is causing it to flicker.  I can find this one, because it's part of a program.  I removed it and replaced it with an on/off plug in Zwave device that was not controlling anything, just there to help the Zwave network.  How can I find that device?

What did you upgrade to? Are you now on eisy with ZMatter dongle?

If so, no you should not have both. ZW was the original Zwave prefix and ZY is the new prefix for UD's ZMatter dongle.

Sounds like the devices still with ZW did not migrate.

Not sure what you are asking, what are you trying to find?

[ctviggen1]

Yes, I am on the Zmatter dongle.

How do I get rid of the ZW?

Basically, I have a zwave on/off device connected to a lamp.  How do I know which device that is? 

With Insteon, there's a network address you can use that's physically printed on the device. I don't see that for zwave devices.

If you don't use that, when I installed them, I only added a single device at a time.  I would then rename this, eg, "main foyer lamp". This would let me know where it is.

The problem with these zwave devices is I added them for the sole reason of making my zwave network stronger around my front door, which has a zwave lock that wouldn't work .... sometimes. I was trying to strengthen the network, and just blanketed the area.  I just plugged them in and that was it.  I didn't care what their names were or where they were, and I didn't use them to control anything.

Now, I want to control one of them that I moved from an outlet to the main foyer to control a lamp. But I have no idea which device this is. 

Does that make sense? 

[ctviggen1]

I should say that I don't have much "real" zwave.  Three ceiling fans, two door locks, one to control my main foyer lamp (and I could use Insteon to control the lamp, but this plug is close to the front door, so want to use zwave to make the network stronger). 

I could therefore reset the zwave network and re-add everything.  I'd prefer not to do that, though, as then I have to find all the programs that use these and redo those too.

Plug a lamp into the outlet and go through each device and turn them off. When the lamp turns off that will be the one you were looking for...

As I said above, the ZW items didn't migrate over. Not sure if you can rerun the migration tool?

If not, you would need to delete them, factory reset each device, and re-add.

I don't see the need to reset Zwave network. However, part of the migration process is correcting the programs for the change in node address.

If you named your devices ZW xxxx prior to migration, then when you migrate the device name will not change.

When in the device's status window, the device ID should show ZY under the device name.

Are you sure about that?

Zwave devices with the prior Zwave board and Zooz stick were named ZW. If you migrate to ZMatter, the name is upgraded to ZY.

Although I see it has been removed from the migration wiki, this use to be specifically called out in the migration instructions.

I believe it still holds true.

[ctviggen1]

Thanks, all. 

I tried finding the single zwave on/off module by turning it off and then on, and couldn't find it.  The problem is that zwave modules aren't highlighted (relative to Insteon, which I have tons of).  So, if I named something X, and don't remember that I named it that, I don't know that it's zwave.

It's possible I could print out all of the devices and whether they are on or off, with the one zwave module being off, then do the same with the one zwave module being on and find it this way. I just am unsure how to do this.

I have never named a Zwave module anything but a real name, like "main foyer lamp".  So, if these have a name like ZW or ZY, I didn't add them.

And I thought I reset the system when upgrading to prevent this. I guess I didn't.

[Techman]

If you create a Topology report [ TOOLS, GERERATE TOPOLOGY] it will generate a list of all your installed devices.

[ctviggen1]

Thanks, that is helpful. 

I realize that I have tons of ZW and ZY entries and have no idea what they are. ZW16 - ZW 19; ZY 2, 4, 5, 6, 7, 8, 12.  I will have to work on those first, then maybe try to figure out what the reals ones are, one by one. 

[Techman]

Some Z-wave devices tend to install nodes that aren't applicable to UD Controllers. I created a folder and moved those unused nodes into the folder to get them out of the way. When you migrated to the Zmatter dongle the Zwave prefix changes from ZW to ZY.

Hi @ctviggen1.

  It sounds like you're confusing a Z-Wave item's "Name" with its "Address". The address can't be changed, and all nodes for a single Z-Wave item will have addresses that start with the common 'ZY026' and then will have more specific #'s after it, like ZY026_005_315. You are not able to change these, and when you click on a node in the Admin Console it will show this address at the top center under the name. The name can be changed but if you don't change it it will fill in with the ZY or ZW number plus some description. If you migrated, the name should be unchanged and will be why you could be seeing ZW numbers...? Anything added after migration will be ZY in the name.

  I'm kinda unsure what you mean by "real ones" - do you mean the nodes that 'actually' do something when you actuate them? For the most part, the "main" node will be an underscore '1' such as ZY026_1. Either way, all nodes that have the same first five digits of address (ie ZY026) are all belonging to one Z-Wave item. Some nodes do nothing, this is normal. As Techman said you can create a folder and move unused ones there to clean up the view. 

  Hope I've helped. 

OH, forgot to mention, in the Admin Console main view, you can click (or double click) the 'Address' title, and it will re-sort all your devices by their Address, which will naturally group all your nodes together for all devices, which comes in very handy if you've renamed devices from their default name. Please try this, it may save you some work. 

Thanks!

Shawn

Yes, before your note (thank you for it though), I was able to click on the Network folder and then that brings up a "Network - Managed Scene" window.  A view of this:

I then clicked on "Address" and it arranged the addresses so all the Zwaves were together.  I then turned on and off the device a few times until I found the device, which had a name like "ZY 005..." and then I renamed it (as foyer lamp) and used it in my programs, replacing the old "foyer lamp" (now called "foyer lamp (old)").

The problem is that I have ZW and ZY and the ZWs are actually "real", here's a portion of the table:

Should I have all these ZWs?   If not, how do I get rid of them? 

And I don't even know what a lot of these are, no idea what or where ZW 18, 19, ZY 2 even are. I THINK the ZW 16 and 17 are small on/off plug ins that I have turned on and do not control, and are there just because they are within a short distance from my front door lock, which was having issues due to poor zwave strength (I think, anyway).

I will use the folder technique, because for what is now my "foyer lamp", I have five entries, of which only one does something I need it to do (turn on/off).  For my "old" foyer lamp, it was dimmable instead of on/off, it also has five entries.  And I'm only keeping it to make the network stronger, as it no longer dims correctly (it causes the light to flash).  But this shows what's up:

I'll move all the stuff I don't use to a folder.

Zwave can add several nodes, some of which don't work with ISY. To help sort it out, right click on a device and look for group devices. Group only appears for the main node. That will arrange sub nodes under the main node.

From your screenshot, the ZW's are in the name, not the address. The name can be anything you want. Typically, unused nodes can be placed in a folder and labeled so you know they are not in use. If you delete them, they usually return.

[ShawnW]

Yes, you can right-click on any node in the left-hand column of the Main view, on the name you want to change, and 'Rename' will be one of the options.
