Leviton decora smart Fan Speed Controller ZW4SF

I bought a couple "Leviton decora smart Fan Speed Controller ZW4SF" devices (Z-Wave) to control some ceiling fans. These are not on the supported hardware list and I did not find the model number (ZW4SF) in any posts.

I am able to include the device with my controller (I'm told on subsequent attempts to include that there is already an ID for it), however when I request Indigo to then "sync" with the device, the sync times out and I'm told that the device is unreachable or has fallen asleep (as if a battery powered device). I suspect that it is reachable because is in within a few inches of another included device.

Because Indigo cannot sync with it, I cannot get any information from the device settings. How should I proceed? I'm hoping that the best answer is not "Return them to Amazon". I like the device for controlling fans and would like to see it supported. I searched plugins but did not find anything that mentioned the model number.

Did you sync without encryption enabled? If not, exclude it and re-include it without encryption.

If that doesn't help, then are you sure the model you bought is for your region? Different Z-Wave module regions use different frequencies and sometimes when purchasing from Amazon the wrong region is sent, in which case it won't be able to communicate with the Z-Wave interface at all.

Lastly, copy/paste the Event Log window results (into a reply) of both the re-include and re-sync attempt so we can see exactly what is occurring.

I tried syncing without encryption enabled (and with it enabled). I just tried to exclude it by deleting the device from the Devices, however, when I try to include it again, I get this in the log:

Oct 28, 2022, 7:44:28 PM
Z-Wave started controller inclusion mode

Oct 28, 2022, 7:44:59 PM
Z-Wave stopped controller inclusion mode
Z-Wave Error the node included has the same ID as a node already in use by Indigo
Z-Wave Error to change the encryption state of the device you must exclude it before re-including it

There was nothing prior about excluding the device.

Trying to "include" again, skipping to the sync part:
Oct 28, 2022, 7:54:53 PM
Z-Wave started controller inclusion mode
Z-Wave stopping controller inclusion mode
Z-Wave stopped controller inclusion mode
Z-Wave Syncing - started for "006 - Mulitlevel Switch"
Z-Wave Syncing - retrieved module neighbors list: 2, 3, 5, 7
Z-Wave Syncing - assigning return route to "006 - Mulitlevel Switch"
Z-Wave Syncing - assigned return route

Oct 28, 2022, 7:55:27 PM
Z-Wave Error Syncing - failed
Z-Wave Error Timeout waiting for "006 - Mulitlevel Switch". Module might be asleep, or is unreachable.

Whenever I try to include the device, I get that same ID message. Is it possible that this device as the same ID (I presume its a Z-Wave address, much like a MAC address?)?

As for the model, the instruction sheet is all English and refers to the FCC and Canada. The complete model number is DI-000-ZW4SF-02A. I tried calling their support line, but they were "in training" and never returned my call.

Deleting the device from Indigo doesn't exclude it from the Z-Wave network. Choose the Interface->Z-Wave->Start Exclusion Mode menu item to put the Z-Wave Controller (Z-Stick, etc.) into exclusion mode then press the button (or do whatever sequence is specified the module's manual) to have it exclude itself from the controller. You'll then be able to include it without encryption and syncing should work. If it doesn't then copy/paste the Event Log contents showing everything (exclude, re-include, re-sync) into a reply.

Also ... I had been running 7.4 and just updated to 2021.1. Reran the add device process, the fan controller was successfully included without encryption, it just fails on the sync process. Tried syncing twice after the inclusion:

The log snipped you posted is not showing that you did the exclusion process. It must be done before trying to re-include it without encryption. Exclude, re-include, re-sync, then copy/paste the Event Log window results of all that into a reply.

My bad - I thought, erroneously, that deleting the included device would also exclude the device. Having formally excluded the device and including it again without encryption, it works now, thanks.

I'm not saying it's necessarily an issue here, but I always exclude every new device out of the box before I try to include it into my Z-Stick or add it to Indigo. In more than one instance I've bought new devices that were already included into another controller. I suspect two possible culprits -- 1) that someone bought and returned the device (with their inclusion still on the device, or 2) that the QA process by the manufacturer missed an exclusion before shipping.

I don't recall having had trouble with a device when I've excluded it first thing. YYMV.
