Smarthings issue with Zigbee after power failure


each time we have a power failure, the charging station can’T reconnect automatically with my 3 zigbee system, Power controller, 2 thermostats.
i found tonight the charging station have now value after the power failure (see below the pictures)
if you have an idea, i will try it.

after power failure

before the power failure

note : the only way to make it work, is if i reset the chargong station (Hub)

Best Regards

Since the web interface is showing that using the Station’s Zigbee radio is off-line after the power outage, it looks like a defect, but I don’t know whether it’s in that specific hub or in the model line. I think you’re going to have to contact official smartthings support on that one. :thinking:

I’m also tagging @Automated_House just because I know he has at least one station in case he has seen any similar behavior. :thinking:

Hello JKP

No battery only Electricity.

Hello i found this not into the support page. it’s sounds like it’s normal for Zigbee systems

Best Regards

Two separate issues.

It’s true that setting “unsecure rejoin” to “true“ might make it easier for some of your zigbee devices to re-join the hub after they’ve lost connection.

But the screenshot that you posted has zeros for the hub itself in all the identifying fields, and says that your Zigbee radio in the hub is turned off. That’s not normal for Zigbee as it indicates that the hub itself failed to recover after the power outage.

It was seeing these entries that caused me to suggest contacting support.

Hello Jd

thanks for the quick response, i already send it to the supports 4 days ago like you suggested to me. still waiting. i guest the are very busy.
i will let you know soon i have an answer.

Best Regards

I think I have the same problem
I’m using one hub and two devices

Hub is a SAMSUNG SmartThings Station EP-P9500 received new December 13, 2023

Firmware is up to date
See Screenshot_20231214-104209_SmartThings.jpg for the firmware version.

The Zigbee devices connected to the hub are:

One Aqara Door and Window Sensor T1
One ThirdReality Smart Button

If I unplug the hub power and after a minute I reconnect the power, all Zigbee devices will be defined as offline. If I try to add a nearby device to the hub, the hub cannot find it. The only solution I found is to reset the hub. But doing so I will need to reconfigure the hub, reconnect all Zigbee devices and reprogram all automatic routine.

Do you think there is a solution to this problem? Or should I return the hub and declare it as not working?

have you tried other things before resetting the hub? like rebooting the hub through the Advanced Web App or removing battery from zigbee devices?

Before 1 minute power off
Advanced Web App > Hub > Zigbee > Functional: true

After 1 minute power off

removing battery from zigbee device
did not fix the problem

Before Advanced Web App > Hub > Reboot
Advanced Web App > Hub > Zigbee > Functional: false

After Advanced Web App > Hub > Reboot
Advanced Web App > Hub > Zigbee > Functional: false

Zigbee devices are still Offline

Something strange happen yesterday, during the night i lost the wi-fi connection of all the switch but not the zigbee on’S (for the first time since i have them).

the only difference is i give them a reserved ip adress, sounds like it’s working for the zigbee but not for the kasa switches, tonight i need to remove the reserved ip on the switch but i will keep it for the zigbee switches only.

Reserving the IP address did NOT fix the problem. All my Zigbee device are offline after power failure / reboot of the hub.

Reserving the IP address did NOT fix the problem.

Still not fix

ughhhh I have been having the exact same problem with my Station as well. I am thinking to just ditch the station and go with the Aeotec hub. Unless you’ve managed to resolve the issue??

I have exact issue and still waiting for updates from smart things support.

Finally i fix the issues with the zigbee systems i have, controler and thermostat.
I BUY the GT130 bridge from Sinopé.

Sorry Smarthing, you can controle the rest of the house but for those zigbee system you don t have it any more.
I can sleep well now :relieved:

I am having the same problem. Is there any solution available? @SmartThings ?

P.s. My station is on the latest firmware available.

Have you tried rebooting the hub using the Advanced Web App or by pulling the power cord.

I have tried multiple times! I also tryed to turn on or off the zigbee rejoin and i have tried to change the zigbee channel but it doesn’t seem to work.

I am still trying my best to get the hub working again. Unfortunally it wont activate the zigbee radio…

Could it be possible that it is officially unavailable to use the smartthings station from outside of the USA? (I am using it in the Netherlands) I just thought about that possibility.

No, Zigbee is The same frequency all over the world and many people are using it in the Netherlands.

Your smartthings account shows that your Zigbee radio is broken. That’s what the “false“ means under the “Zigbee functional“ field in your first screenshot from

It can happen, just as a television, or a refrigerator or a microwave oven can have a functional breakdown.

This forum was set up several years ago so that customers could help other customers with the SmartThings platform. But for a problem like this, you have to contact official support, they may be able to see more from their side, but it may just be that you would have to get a new hub. :disappointed_relieved:

How long ago did you buy your hub and where did you buy it from?
