Z-Wave Repair Results

I’ve had some Z-wave connectivity issues crop up during the last week or two (maybe tied to the latest firmware push as I’ve seen someone else suggest, but I also just replaced a device) and I’ve run a Z-wave repair to try and correct it. I’m not seeing any reliable way to view the results of the repair; I’m hoping I’m just missing it, and someone can correct me.

Option 1, run in ST app (android): results are slow to appear. If the screen shuts off during the repair process, when it’s woken back up, any previously listed failures disappear. Given the time it takes for a repair to complete, keeping the screen on throughout is not practical.

Option 2, run from Advanced user web interface: no results are listed, just a confirmation that the repair has started.

The results that I’ve been able to see have also not been that helpful. I recall in the old IDE, you could monitor the results log and get specific errors. What we get now seems to just be “something went wrong”. I hope this isn’t indicative of a lack of continuing support for Z-wave in the hubs that do have it, in addition to dropping it from new hubs.

I worked fine for me. It only took a couple minutes

It found 1 problem a plug that has been unplugged since Christmas.

Interesting that it showed that one three times. That would have been three different errors in the old IDE - something like unable to communicate, unable to set new route, etc.

Hi @MarkTr

The engineering team has requested some additional information to help analyze the issue.
Could you please select one device, reproduce the error, and then send us the corresponding hub logs?

Hub logs

Provide the Hub logs through the my.smartthings.com:

  1. In the my.smartthings, enter “your hubs”
  2. Enter the corresponding Hub
  3. Click on “Dump Hub Logs”
  4. Change the reason for requesting hub logs if needed
  5. Click on “Dump Hub Logs”
  6. Confirm that the request is submitted
    Note: If you have more than one Hub, the name of the one involved in the issue.

Also, please include the timestamp and timezone of when the issue occurred — this will help us locate the exact moment in the logs.

Example: September 30th, 2025 - 9:45 AM (GMT-6)

Also, support access to your account

  1. Confirm the email account registered in the forum is the same one you use for SmartThings. If not, please share it with me over DM.

Spent some time repairing things last night, including a full power cycle on the hub instead of a soft restart. Several items that worked last night show as offline this morning:

Main Bedroom Fan

Molly Light

Main Iris Plug ZW (z wave repeater in a zigbee smart plug, so no control, which means nothing visible in history)

Main Closet Light after exclude, factory reset and include, is responsive to app commands but occasionally flicks on and immediately off in a way that feels like acknowledgement of network inclusion or something similar.

Living Room Scene Controller had included with all zeros on previous attempts, this time it included correctly and picked up the proper driver.

Lots of z wave commands are laggy this morning. I can easily turn a switch off from the app and see that reflected in its status, but it takes 15-20 seconds to turn back on.

Hub logs have been dumped.

Hi @MarkTr
Thanks for the info.

From what you mentioned, it sounds like the following three devices are the ones showing as offline, is that right?

  • Main Bedroom Fan
  • Molly Light
  • Main Iris Plug ZW

Just a couple of questions to better understand the rest:

  • Main Closet Light: you said it sometimes flicks on and off really quickly. Does it ever go offline, or is that the only issue?
  • Living Room Scene Controller: is this one also going offline, or is something else happening with it?
  • About the delay with Z-Wave commands : having a delay is different from devices going offline, so we’d need a bit more detail to check the logs properly.
    For example, something like:
    “I turned on Switch 1 at 1:00 PM UTC, and it turned off at 1:15 PM” , that kind of info helps us line things up in the logs.
    After you reproduce the issue, you can send us the logs and include the exact time the problem happened, just like in the example above. That will help the team match it up in the system.

Also, please make sure to grant us access to your account so we can keep looking into it on our side.

I cycled the breaker for the main bedroom; that seems to have brought the Iris plug back online.

Molly Light was in the ‘offline devices’ list at the time I wrote that post, but I haven’t done anything to fix it and the history shows it being mostly online since then so I’m not sure what happened.

Main Bedroom Fan shows activities in the history last night but is offline currently so I’m not sure if it ever really came online since Saturday morning. I haven’t done anything that would have repaired it.

Since hard resetting the switch and re-including it, it’s stayed online as far as I’ve noticed. I’m going to ask Zooz support for input on the on-off flicker.

This seems to have stayed online since cycling the hub and also the living room breaker; no further issues at this time.

Will try to set aside some time to experiment with this tonight.

Edited to add: I forgot that this was an issue specifically with the Main Closet Light using the Zooz custom driver. Turning off via the app was immediate, but following that by turning it on would just result in a spinning status. Waiting for that to time out and trying again would sometimes work. Using the standard Z-Wave Switch driver eliminated the issue. I don’t need any of the advanced features of the other driver so this is less critical but still odd. I’ve included this with my support request to Zooz and will flag it in the custom driver thread as well.

I think this is already granted without an expiration; let me know if you’re not able to see.

Could you please confirm which email you use for SmartThings and send it to me via DM?
