Samsung Smartthings Outlet drops off network

General Discussion
1

I have a Smartthings setup at my house that uses a Smartthings V3 Hub (before Aeotec). I have a few door sensors, Buttons, motion detectors, and several water sensors. They are all the original Samsung brand with the addition of a couple Aeotec water sensors. I have a Z-wave water shutoff valve and a GE light switch. There are several Phillips Hue bulbs that are controlled by Smartthings and bridged through a Philips Hue bridge.

When I first set up the configuration several years ago, I had Zigbee devices that would drop offline. I ended up adding a few Samsung Smartthings Outlets around the house to act as Zigbee repeaters. This set up worked flawlessly until a couple of weeks ago.

What is happing is that every few nights the Samsung outlets all drop offline at the same time. Consequently, any ZigBee device that is routed through the outlet also drops offline. All other Zigbee devices, the Z-wave devices, and the Hue bulbs continue to work. If I reboot the Smartthings hub everything comes back online.

I did note that the Driver software for the Smarthings outlet was updated around Oct 27th, 2025, but I have not been able to find any other complaints about this problem. Last night I disconnected all the Smartthings outlets to see if my network will work without repeaters.

Any ideas?

Try power cycling all of the outlets.

There seems to be a variety of reported Zigbee issues at the moment.

The one I’ve been suffering from for weeks is that every now and again I seem to lose my entire mesh. I suspect that actually my directly connected devices are fine, it is just my routers and everything routing through them that lose connectivity with the hub. The devices don’t seem to actually get reported offline unless I reboot the hub or wait a long time (neither of which I tend to do). For me the instant cure is to power cycle one of the routers, though it can’t always be just any one. It is somewhat frustrating to say the least.

Every time I see a new Zigbee issue reported the symptoms aren’t quite the same as I see. Yours sounded promising until you said rebooting the hub helped.

I have done that. I also tried deleting the outlet devices and re-adding them.

Hi, @jdh3rd
I can open a report for the engineering team to check why the devices are being marked offline.
For this, you need to do and provide the following:

  1. Re-connect them to SmartThings
  2. After you do, submit the hub logs for the engineering team to check any events of this process that could be helpful
  1. In the Advanced Users app, enter the “Hubs” section
  2. Enter the corresponding Hub and click on “Dump Hub logs”
  3. Confirm the process by clicking on “Dump Hub logs” again in the pop-up.
  4. You’ll get a green box at the top confirming the Hub logs were requested.
  1. Then, when the device becomes offline, take note of the date and time. If they go offline while you’re sleeping, provide a time range when it could’ve happened, including your timezone. For example: November 4th at 16:20 CST or from 22:00 to 5:00 am the next day
  2. And also, send the hub logs as soon as possible (same steps as above).
  3. Finally, open support access to your account:
