Aeotec Smart Home Hub/2018/2015 Model Hub Firmware Hotfix Notes - 0.45.11

@Claudio_Garofalo Good afternoon, I was also experiencing this, I removed several devices little by little until I found the problem. My hub started to improve from yesterday to today. The cause of the problem is one of the zigbee or z-wave devices not picking up properly causing the Hub to crash. Another problem that can happen is that the hub has full or almost full memory. I also saw reports from the smartthings forum guys reporting offline status issues on Zigbee end device devices. Smartthings needs to release a new firmware that fixes bugs, crashes of Smartthings and Aeotec Hubs , constant offline that forces you to reboot the hub to get back to normal , problems with hub memory full or almost full (need to optimize this), bugs in drivers. and also unable to know the status of the device. Smartthings needs to improve several issues issues.


I’m glad this just isn’t me…the past week has been crazy. Hub has been going on and offline and then randomly would show offline but automations would work. So odd…but sadly all my zigbee devices would go offline.

I really hope a software update comes out soon to fix this as there wasn’t any issues before


Yes i hope this get fixed soon. I dont know what else to do. Can use anything throught the app or pc portal. What a mess.

Generally this has been a terrible experience for this and related service updates…

As of tonight my entire ST zigbee network of 60+ devices that had been functioning for a better than 2 1/2 years is completely down. The hub is up and has been PORed… But ALL devices as of this afternoon are showing offline. There have been zero config changes to the system.

It is clear that that since your service and hub software changes to support the new Thread standards, the ST zigbee experience has become a non starter from a real product point of view. Just an unusable mess.

I have a conversation going with ST 1st tier support and the ticket # is [1427874]. And this is being escalated to you guys.

I have a strong technical background and would be willing speak with your ST engineers.

Just so you know… Your are forcing your base to move to other solutions like Home Assistant. Very bad business look.


Good morning, My Hub has stabilized, after removing several devices until it stabilizes, I am adding it little by little to find the possible hub crash that caused constant offline (find the problematic device that knocked out the entire zigbee mesh and the z-wave mesh). For now the last devices I removed I didn’t re-add back, but I’ll do the test to find the real problem. Another problem that has been happening is in the Smartthings application, when you click on a device, the following message appears: It was not possible to know the status of the device. This bug is annoying, they need to fix this bug. And also solve the problem of HUB with full or almost full memory. Another thing that needs to be added after the End of Groovy IDE, how much in the samsung account/ smartthings account that accesses the drivers and/or how much in the Smartthings application the utilities options of the HUB Smartthings the HUB Reset option, Change the Zigbee Channel , Repair Zigbee network, repair Z-Wave network. These Utilities need to be added in the Smartthings App, they are still missing. I hope they release firmware updates for the HUBs that fix the flaws left by the 0.45.11 update and also update the Smartthings app by adding these options after the Groovy IDE is gone.

Having the same issue as a lot of the others with “Memory” issues and frequent Blue lights requiring a reboot. Removing a lot of devices has only helped temporarily. But within 24hrs it back to Memory full and back to blue lights. Something isn’t quite right with the firmware.

This is such a joke. Devices keep droping off. Can’t control the light,lock and thermostat correctly. When are they going to get a fix for this issuse. Its going on several weeks. Try the app and theres issuse try the pc app and theres issuee. FIX the zigbee issuse guyS. Wake up and smell the roses. If you watch it you see when the apl goes offline you loose the zigbee controler on the app.


Having many of the same issues reported by others. I primarily use 5 devices attached to my smartthings hub.
1x Multipurpose sensor
3x bulbs (all Sengled)
1x Samsung Stove

With the exception of the Stove, all of these devices have been a nightmare over the past couple months, requiring me to reboot the hub very frequently in order to retain functionality. To the point where I considered attaching a smart switch to its power supply and rebooting it periodically which is excessive.

It frustrated me enough to have me start digging in again this evening. I am watching my devices periodically shows a offline and then sometimes online in the ST app.

Is there a more obvious way of looking @ logs and debugging this from the user end? The events listing for the hub does not seem to be of any real value.

Do you have any repeating Zigbee devices? The stove might. But the others do not. A strong Zigbee mesh is best when there is a repeating device for every 4-6 non repeating devices.

I don’t have any repeating devices. If it’s possibly signal strength, maybe it would make sense for me to move the hub though that would require figuring how to switch it to WiFi from Ethernet.

There is nothing wrong with your system/setup, I bet you everything was working fine until 2 months ago. Same here, my ST was working very well for almost 4 years, until about 2 months ago. They “updated” the hub firmware to support Thread/Matter (which right now btw it’s just vaporware) and by doing that they broke Zigbee functionality. Every other day I see tweets from Smartthings bragging about how great Matter is and how they are one of the first companies to support it. Clap clap.
2 months are years in IT, you cannot keep a platform basically useless or with limited functionally this long. Big mess. At this point I don’t think they know what they are doing.

If you only have 5 Zigbee devices, you probably don’t need any repeaters, unless your devices are too far away from the hub. The hub itself can parent several dozen battery powered devices. It’s not necessarily the best way to set up a network, but it should work again, if everything is close enough together, physically.

FAQ: 32 Zigbee direct connection device limit?

That timeframe sounds about right. I mean I periodically had issues before that where I would have to reboot devices (which I chalked up to being normal) but now it’s constant. Devices stay online for 45min to an hour and then go offline.

The release notes for firmware 45.9 mention that they “upgraded the ZigBee stack” for the V3 & Aeotec hubs.

Then 45.11 had ZigBee fixes.

While not everyone is including that info, it seems that most of the ZigBee issues are with the newer hubs.

I had disconnections with zigbee channel 18, now I am using channel 20 and no disconnections.

I agreed - it was the first Thread/Matter firmware (the one before 45.11) and related service updates. Total mess.

My system is composed of 54 or so GE Zigbee in-wall dimmers and a few switches - all Zigbee repeaters.


Please add ticket # 1427874. Highly impacted - entire - once stable system - is completely down. 60 devices.

My V3 ST Hub is running firmware 000.045.00011.
Is this the same firmware that everyone is referring to as 45.11?

yes, they’re the same

It happened again, 3rd time since I got 45.11.
first two times were a week apart, the third time was after a further 3 weeks.
This time most devices went offline apart from temperature sensors.
After a reboot not all devices came back.
Currently my kitchen multi gang zemismart switch is unresponsive.
I had none of these issues until 45.11 arrived (Aeotec hub v3).

It would be really useful if Samsung could post an update on investigations here or any tips to diagnose or work around the issue.

Hub instability just coming up to Christmas is really bad timing.

Update: I had to power cycle the circuit to get the zemismart switch back, pushing the touch sensitive panel didn’t even turn the lights on or off.
