We will begin rolling out Samsung SmartThings Hub firmware version 0.61.6 starting on June 15, 2026. This will be a phased rollout, so that we can keep a close eye on any issues that arise, so your hub may not be updated immediately. Once downloaded, your Hub will briefly go offline as it reboots and applies the update; most customers will experience less than one minute of downtime. We will update the status page when the release is complete.
Hub Target
Samsung SmartThings Hub 2015 (Hub v2)
Samsung SmartThings Hub 2018 (Hub v3)
Aeotec Smart Home Hub
Aeotec Smart Home Hub 2
ThingsOne Smart Home Hub
Release Period: June 15th, 2026 ~ June 26th, 2026
Note that this release will be spread out over the course of a week, so you may not see your Hub update on the first day of the release period. This release period is an estimate, so the rate of hubs updated and final completion date may vary slightly within the timeframe. Please check the status page for more up to date information on this release.
Release Notes
Hub Firmware
Improved Device Health Algorithm for Zigbee Devices
Zigbee device online/offline status will now be determined more accurately based on each device’s reported communication interval.
This feature will be rolled out gradually after the release is complete. Once enabled, Users should see a more accurate representation of their Zigbee device status. The new mechanism inspects each device’s configured reporting interval to determine how long to wait before considering the device offline.
As part of this improvement, Button and Remote devices will now be individually tracked. Previously, these devices could appear online as long as the Hub’s Zigbee network was functional.
Improved reconnection time for Matter devices following power cycling or battery replacement
Various bug fixes and optimizations
Edge Drivers
Matter 1.5 Device Type Support
Closures support added to matter-window-covering driver
Soil Sensor support added to matter-sensor driver
Irrigation System support added to matter-switch driver
Latency Improvements for Knob-controlled bulbs
Allow Zigbee and Hue lights to be controlled by Knobs
Just came home from work to find all of my local (Zigbee & Zwave) devices and hub offline with light a solid blue. Mobile app notification reports that hub went offline at 1:25PM ̶E̶S̶T̶ EDT, which is more than two and half hours ago. V3 (2018) hub firmware version is 000.060.00012. Performed normal routine of disconnect/reconnect hub power, restart modem and router did not help. What is it this time?
I posted in this thread because I believe that my hub tried to update its firmware but did not successfully complete. Yes, I’ve checked the Web Dashboard but everything is blank (no idea if that’s normal, or not).
Got up yesterday morning to find the majority of my zigbee light switches offline. Turned Smartthings hub v3 off and on, same result. Turned the light circuit off and on and the switches worked manually then froze again.
Restarted Modem, did not help.
Logged on to advanced web app and can confirm Hub is running 0.61.6
Two of my v2 hub updated to 61.6 earlier today and now I have about 10 zigbee devices offline. They are mostly Tuya battery powered sensors (temperature/humidity, leak, contacts and motion) using @Mariano_Colmenarejo’s drivers. Rebooting the hubs has not helped. Some of the devices have come back online only to go offline again.
Three of them are temperature and humidity sensors with child thermostats used for heating, so I can’t switch to a different driver without loosing the thermostat capabilities. Fortunately it summer and there is time to find a solution.
I thought v61.6 was supposed to minimize Zigbee offline problems, not create them.
Yep, I had similar experience here, on v4 hub. A range of tuya motion and temp/humidity sensors went offline. I got most back by taking out batteries and replacing them, but then they dropped off again.
So last night I rebooted the hub again, and thus far they have stayed online, but it’s too soon to say if that’s sorted it,
@Declankh, I checked your account and also see the devices are online. When this kind of event happens, it is important that you send the hub logs before resetting the hub so they get saved in the server and the team can check what happened.
Account access has been granted and email address is the same as used on forum.
Both my Home and Cabin locations are affected. The problem v2 hubs are called Home and Cabin.
At the Cabin location 4 devices are off line because they are turned off for the summer. They are heat tape plug, bathroom heat, dining room heat, and living room heat. So ignore these devices.
All other offline devices are both locations are new problems since yesterdays firmware update.
Update: Conditions have at least temporarily improved.
Home location: 2 leak and 1 contact Zigbee sensors continue to go on and off line. These sensors have never been a problem before.
Cabin location: Only 1 hard wired Zigbee switch is currently off line. It will not come back on line until I visit and cycle the breaker feeding it. This switch does this a couple times a year.
After weeks of trouble-free operation, I suddenly lost half of my battery-powered Zigbee sensors right after installing the new firmware. I had to re-pair all of them. Other devices are also reporting as offline after months of flawless performance. Let’s see how things go from here…
Asked him for more details (vendor/models), waiting for a response.
Edit: 8 devices offline, all of them are Aqara Door and Window Sensor T1, DW-S03D, Zigbee model ID: MCCGQ12LM.
The Zigbee channel on my Home hub was manually set to Channel 11 on Sept. 21, 2021 and it still on Channel 11 today. So that didn’t cause my problems at this location.
The Zigbee channel on my Cabin hub is currently 20, but I don’t know what it was prior to the update.
