Complete frustration with my system

I really have to wonder what SmartThings Support is able to do about such relatively complex environments.

It is estimated (based on hints here and there, though I wish the industry did more research) that most of SmartThings’s million customers have 15 devices or fewer. If you take that into account, then both Support and Product management would not be getting an impression that the issues you are experiencing are common.

The recommendation I have is to meticulously isolate the issue or issues. A single misbehaving node in the ZigBee or Z-Wave mesh can mess up the entire mesh, in completely non-deterministic ways.

As can a bug in the Hub firmware (which, unfortunately, is a variable outside of the Customer’s control).

To isolate? Well… Disconnect everything. Everything. Then add one device at a time. Just a few devices. Wait, if no problems, add a few more. You can perhaps do the distinct RF’s in parallel (i.e., Add a couple ZigBee and a couple Z-Wave at the same time, since these meshes don’t overlap); but don’t get rushed or cocky.

And … ditto, ditto, ditto to this:


If you are using the Classic app, then don’t forget to turn off Device Health (under the hamburger More tab) which ironically seems to cause more problems than it solves.


What system are you using now?

I have the same tplink setup outside my smartthings just in case it needed to be rebooted. I’ve shut it down for about 15 minutes early in the morning and by the time I get home most of the devices are back online… but there are always around 8 that need to be reset and readded. I have waited three days just to make sure and they never become active until after a manual reset.

Interesting… I know I have at least one repeater in every room. Some have two. Maybe I have to turn everything off, start with repeaters first and branch out. What a PIA but I’m willing to try anything at this point.

I’ve read about not having a wifi router next to smartthings which it’s not… should I move the hue hub since it is nearby? The hue system has been rock solid. In fact, the Hue hub is upstairs and all my hue bulbs are downstairs… still I have had no problems at all with it.

Thank you. Yes I made sure I did this. I read about it in many many posts lol.

Yea that’s nasty… I have switched to Hubitat.
It’s not perfect, and it’s missing some big things that that “normal” users might find as a deal breaker. BUT it’s very stable once you’ve set it up.

I feel your pain. :disappointed_relieved: unfortunately, many people have gotten to this point over the years. It’s up to you whether you want to try to continue with SmartThings or move onto another system, but although they have continued to promise better reliability since the summer of 2015, they still have an MFOP (Maintenance free operating maintenance free operating period) of about two weeks.

That’s worth it to many people in order to get the flexibility and power of a SmartThings operating system, but not to everybody.

In my own case, because I have to pay someone else to do any maintenance, even just changing batteries (I am quadriparetic), I need an MFOP of at least six months and preferably 12. I don’t expect any system to be perfect, but I do need my home automation critical systems to hit this target. I get that pretty easily from a number of HA systems, including the hue bridge, Amazon echo, Logitech harmony, Lutron Caseta, apple’s HomeKit and even wink these days. But not ST. :disappointed_relieved: So I have moved all of my critical systems off of it for now.

I do continue to use ST for convenience notifications like a reminder that the guestroom window is open when rain is expected and the guest is away from the house. It just does that much better than anything else in its price range.

So different things work for different people. If you want to, you can start trying to diagnose some of the issues and work through one at a time, but While you can make some improvements, most of the issues are not local problems. They just have to do with the fragility of the platform design And the very high rate of change introduced.

But there’s definitely no point in raising your stress levels over it. Smartthings is what it is, and it is a fun and exciting system for many people. And if you want to build a Jetsons house, it definitely offers a huge amount of Power for relatively small investment in money. But, as you’ve noticed, it does require a significant investment in time, including time spent troubleshooting problems which mysteriously appear without warning.

There are lots of alternatives out there these days, just depending on your own needs, preferences, and budget, so it all comes down to what you need. Different things work for different people. :sunglasses:

Unfortunately, I don’t have much personal experience with this kind of issue.

All my zigbee Xiaomi sensors talk directly to my hub without a repeater and have been flawless. I even have a few outside. I assume I have less than 32, but getting close.

I have 2 Ring doorbells, and a couple of ESP2866s and a couple of Kasa wifi plugs and a Harmony. Everything else in my house is zwave (switches, outlets, schlage locks,etc.)

I have plenty of devices… IDE says over 90, but probably only 50 to 70 are physical. My two story floorplan is compact and no larger than 2000 sqft. My v2 hub sits right next to my wifi access point on the second floor. I have a wifi extender access point on the first floor to help the Rings. I do occassionally need to run a zwave repair when I notice one of the schlage locks failed to report an event. It’s usually a nearby switch or outlet in the mesh that is the culprit. But sometimes it’s just time to swap the batteries.

It is not very clear which one of your mesh networks is having issues. You likely have:

  • Zigbee network for your Hue bulbs
  • Zigbee network for your Osram bulbs (I believe it has its own little hub, right?)
  • Zigbee network for devices connected directly to SmartThings hub
  • Zwave network for devices connected directly to SmartThings hub

The first 3 all share the same band with Wifi. Might be worth trying to figure out what Zigbee channels your 3 networks are using to see if they may be causing interference to each other. I would also check your wifi settings to see channel bandwidth and power. Since 2.4GHz is so crowded I only use it for low bandwidth devices therefore I keep the power quite low and the channel bandwidth is at the lowest 20MHz setting. All my high throughput wifi devices are on 5GHz ISM band where they can get a bit more of my 1Gbps ISP speed.

This may help you with figuring out whether your networks are suffering from interference:

Keep in mind that interference may come from other devices too… your microwave also operates at 2.4GHz and if poorly shielded it can knock your other 2.4GHz devices out while operating. Many years ago my Wifi connection would go out when the microwave was running. I now have 4 Ubiquiti Unifi APs around the house and use all 3 of the main 2.4GHz channels (1, 6, 11) without any perceivable interference.

I’ve read many postings about bulbs either not working well as repeaters and if any of those are used as regular bulbs where power to them is turned on/off then that might be causing issues too as they can only operate as repeaters IF powered. I prefer using in wall dimmers/switches to control lights so I only have Hue/LiFX in areas where I want color otherwise it is all done via in wall dimmers/switches. I also avoid products like Osram Lightify as I do NOT want to add more mesh networks to my already crowded airwaves.

I just had a case of this… I occasionally have very annoying blackouts that last a fraction of a second. Might be brown out but it seems more like a total loss of power. Some random devices, such as Enerwave outlets, tend to lock up totally or partially when that happens. When it is total they are just frozen, while when partial they seem to operate (turn on/off remotely) but they are likely causing havoc on the mesh network causing other devices to malfunction. The latest occurrence was this weekend… I was running network repairs to try to fix issues with devices and very large numbers of devices were reporting issues. While many of those devices were still responding, things were either slow or not working right (sorry for vague description). I used the Zwave Toolbox to troubleshoot the devices and found that many of the devices showing up in the network repair as having issues were marked as “not responding” on the toolbox, or had a high number of failed frames. While I did not figure out what device was causing the issues, my suspicions were with an Enerwave metering outlet that has frozen with momentary blackouts many times before. I therefore resorted to powering down that area of the house (breaker) and powering it back up a few seconds later. When I ran the network repair again, and the tests with the Zwave Toolbox, all issues in that section had gone away and things were responding much faster and reliably.

As many have told you in this thread, turn “Device Health” off. It caused me so many issues that all went away with it permanently off.

I recently migrated to SmartThings Hub v3 and ran into quite a few issues setting the networks back up. A couple issues that caused device reliability issues were due to:

  • botched includes where the device appeared to be working but it was erratic (most common on GE Motion Switch in my home)
  • VERY chatty power reporting devices… the biggest offender is the Aeon HEM that spams my network with tons of messages. It may also be causing other issues, not sure, as once I excluded and reset it, all my issues in that area of the house seemed to go away as well.

While this might be a shotgun approach, it might resolve the issue but I am not sure you would find out what was causing it as you tore everything down. I would first try to isolate the issues to a particular set of devices and network. If the issues are spanning across ALL mesh networks then you either have multiple issues or an issue with the common denominator (the hub). If you can narrow down the issues with a set of devices that share something in common (ie all zwave, all osram, at whatever…) then I would tear down any devices that seem to have the most issues if you want to try to minimize the work and possibly figure out the troublesome device (although if you exclude a device having issues and once re-included it works, it might have been the device or simply it found a more reliable path to the hub…). Another approach is to rebuild the network starting with wired devices closest to the hub and moving out so that you can build a strong mesh network backbone. I would run network repairs to propagate the new routing too a few times during this process.

Good luck!


Osram bulbs Connect directly to the smartthings hub, you cannot use the gateway with a SmartThings system. (It’s a pure zigbee coordinator, not a Wi-Fi/zigbee bridge like hue).

Zigbee bulbs Connected directly to the smartthings hub, including Osram, can mess up your zigbee mesh by losing messages which they are given to repeat. :disappointed_relieved:

Official knowledgebase article:

Note: SYLVANIA bulbs have a known firmware issue that can occasionally cause them to fail as ZigBee repeaters. This can potentially cause other ZigBee devices to fail to update and/or respond.


For the bulbs, are you leaving them constantly powered? i.e. not turning them off at the swtich

Understandably you have a lot of device, but can you share the make/model of all the devices you are using? This could help us to possibly point out any known problem devices. As others have mentioned, there are devices that will act as repeaters in your Z-Wave and Zigbee networks but they can do a fairly poor job and wreck havoc on your home network. When these repeaters ‘malfunction’ the issue can seem sporadic and manifest in ways similar to what you are describing with seemingly random devices dropping off the network.

There are also devices that don’t adhere totally to the Zigbee or Z-Wave spec and they can have poor reliability when connected to a router device. Xiaomi devices are a common example of a device that does not follow all aspects of the Zigbee spec and can struggle to stay reliably connected to the network if it is not connected directly to the hub.


Sorry for the delay in replying. I do not have any Xiaomi devices, even though I was looking at them because of the price… I just heard way to many things about them to deal with them.
Same thing with the GE Link Bulbs. I took them out because of people saying they flood the network with garbage. I also just decided to remove every WeMo bulb (I had six scattered throughout the house) this past week and replaced them with Hue bulbs since it was long overdue.

I did the Z-Wave repair which found orphaned modules and I was able to delete those manually, so now that is clear. Thanks for everyone’s help and input. I will say, after replacing those Wemos the system does seem better…

Thanks again.


I would just like everyone to know that it has been about two weeks now since I replaced the WeMo bulbs with Hues and I can report I have not had one problem. The WeMo bulbs were my longest “running” devices in my home so basically, it has been causing me issues from the start, I just didn’t realize it. The more devices I added the more problems I had. I figured by adding ZigBee plugs that I could strengthen my network and fix it. Well, it seems that whatever devices used the WeMo bulbs as a repeater then it would just drop. I do wish there was an app that allowed us to see what devices were piggybacking off of the repeaters. I also wish there was a way to turn off repeater mode on devices. Oh well.

I would like to thank Broderick for his help. Now, as I hit reply I’ll be anxiously hoping my system doesn’t start crashing lol. Thanks everyone.


Although relatively more expensive, I do find that Hue bulbs seem to be the most reliable. I replaced 10 of my Ge Link bulbs with Hue and Sengled bulbs. The Sengled bulbs are better than the Ge Link bulbs but even they have dropped off my network occasionally. The Hue bulbs, however have been rock solid.


Hues are the best. Spend a few dollars more, hit the bar on Fridays, WAF goes high, allowed to get more hues! Life is good! Use the native app or Alexa darling. Life is much better. :wink:


Long-time IRIS User, just started with ST last Sunday (2/3). I had about 75 devices with IRIS, including ~35 GE zWave plugs (12721) and paddle Switches. Using the ST V3 hub. I used the new ST app to reset the devices and then pair to ST, and was amazed at the ease of this without moving the Hub. Located centrally in a 2 story home, connected to my 5G Wifi.

Everything was good, good bye IRIS. Next day (2/4) Started moving the KwikSet Locks, Smoke & CO2, Siren, etc, and while these battery operated devices were a bit more problematic, eventually got them connected. Moved on the IRIS Gen 2 Smart Plugs (3210-L) and following this forum, paired both the outlet as Zigbee then the zWave which function as a repeater. Ran the Zwave repair after each step. Noticed on 2/5, 3 previously connected devices were off-line. followed a support thread to Edit/Update which had no affect. This morning, noticed another device OFFLINE & started a zWAVE and after 4 hours, ALL zWAVE devices are off-line. I know this can take awhile, but my experience with IRIS was devices would pop in and out during the utility, but never saw a complete drop of every item. Scrolling through the EVENTs on the hub, seeing “Network repair for xxxxxxx [0B]: Did not finish updating mess Information” for each devices. The GEN2 plugs on zigbee appear to still be functioning.

Perhaps it will clear, but given the number of devices, is there a more reliable solution to provide basic functionality to control groups of plugs, switches, door & wind sensors?

That’s the million dollar question - You’ll find a couple dozen threads on this topic throughout the forum with varying recommendations and conclusions.

SmartThings is the #1 option in this particular space: multi protocol, growing device list, somewhat open (custom device handlers and SmartApps), no recurring costs, very inexpensive hub, and the largest active peer-support groups (this, and SmartThings Users Group)

There are a quite a few customers with 75 to even 300 devices (inadvisable) who somehow have achieved stability and satisfaction.

Every other platform will either have just as bad issues in one way or another, or require compromise in flexibility and/or cost.

The prevailing theory is that SmartThings is “breaking things fast” in order to try to achieve stability as quickly as possible, even while inconveniencing current customers.

A popular suggested alternative is the startup Hubitat because it was based on SmartThings design but runs locally. But such a young small company comes with different risks.

Spend some time exploring this Community Forum. You may find easy assistance to your specific Z-Wave issues (or the current status of remediation) as well as the “alternatives” Topics.


Thanks and as an update, finally rebooted the Hub and immediately reran the zWave Repair. Ran for about 2 hours, and most of the items came back on-line. Currently have 3 generic GE devices off-line, all close to the hub and literally less than 10 feet from other devices that are online. I also have noticed the zWave Repeater device included in the IRIS 3210-L Smart Plug are now all off-line. The logs are throwing the following error for these “3:30:06 PM: debug Parse returned ManufacturerSpecificReport(productTypeId: 1, manufacturerId: 582, manufacturerName: null, productId: 1)”. The forum indicates there needs to be a piece of code for this device to be added to the IDE file, but do not currently have any clue how to do this.

As far as the other 3 GE devices, I assume I can just Delete, Exclude and Repair?

I’m glad to hear you are having some success. The IDE is the web based programing interface. You can program device handers and apps to add in to ST. You can access the IDE here:

There are instructions for how to add a device handler (DH) to the IDE and publish for use by yourself. JD has some good information here:

I would expect that you will be able the re-add the GE devices.
