Samsung SmartThings Hub (2018) discussion (Model GP-U999SJVLGDA aka V3)

Assuming you have a convenient Ethernet port 10+ feet away from your WiFi router, I’d get V2 for the extra computing power. It looks like they killed local cameras already even for V2. Battery backup is :man_shrugging:t2:

At launch all devices will be joined with the ZHA key and the Secure Mode setting will control whether or not unsecure rejoins are allowed. In a future release users will be able to join Zigbee 3 devices with the install code or ZHA device with the ZHA key.

You’ll need to use the new SmartThings app to claim the hub but once claimed you can use the Classic app if you’d like.

I’m getting closer to just dumping ST and moving to OpenHAB (https://www.openhab.org/).

Any progress on backups? Anyone migrating from one hub to another needs backup capability (as well as anyone else wanting to protect their hours of hard work)

Remember when the V2 was announced and people were saying “what’s the point?” And I kept saying “zwave plus, zwave plus, zwave plus”?

We’ve got the same situation here, in that the V3 will be capable of supporting significantly better technical security features than the V2. It should be S2 certified for Z wave, although admittedly we still have to wait and see on that. And it will be zigbee 3.0 certified, although it won’t enforce all of the advanced security features on the zigbee side in order to allow for compatibility with legacy devices.

All of that gets into super technical details that you won’t notice necessarily on an every day basis, but it does mean that those who are concerned about security issues should find that the V3 scores notably higher on those factors than the V2.

For this reason alone, I think it’s justified in calling it a new generation.

A lot of people won’t care about the differences, particularly if they have already been operating a home automation network based on the previous generation, but I do think there are people who will care. :sunglasses:

Bestbuy had these in stock yesterday. I tried to buy one but they told me it didnt come out until today. Today there is no sign of them on BestBuy’s website. Anyone know what the deal is?

I think they plan on updating the V2 hub for zigbee 3.0, too. Not sure about S2. @posborne might know more about that. Still, definitely should be considered a new generation.

I’m a ST v1 user and currently in the market for a mesh wi-fi system. Was favoring the new Plume Superpod bundle (also considering the Orbi). This new Smartthings Multi-pack seems to kill two birds with one stone.

Is the Plume Cloud the magic, or is it the hardware

Z-Wave S2 support is in development and definitely considered a priority. For V3 at launch, we received an exemption on the S2 features based on the migration path forward and status of current development efforts (which have involved both parties).

@Kianoosh_Karami may be able to answer any more detailed questions you may have.

For Zigbee 3.0 and Z-Wave S2, I believe both the V2 and V3 support the required hardware to support the required upgrades. Although these updates may not launch for all hub targets at the same time, it is certainly our desire to support new version of these core protocols on all platforms that Work as a SmartThings Hub. To the extent that the V2/V3 are both platforms fully managed by the core SmartThings team I would expect to eventually see these platforms come close to converging on the software they run over time.

With that being said, with the chance to manufacture a new version of the hub we had the chance to improve security of the core software platform in several ways that would be impossible (or inadvisable) to do for units in field. Most of these are not noticeable to a user but the high-level bullet points are:

  • Traffic between host process and Zigbee chip are now encrypted using a key that is unique per device.
  • ARM TrustZone features (via OPTEE) are utilized to provide a strong, isolated environment for storing/accessing auth keys and other sensitive data. This gets technical quick, but basically this means that even a root compromise of the main OS (Linux) would not compromise items owned by the “Secure operating sytem.” This is another security layer we are using (and can expand) to protect users from attacks (or limit the damage caused by a successful attack).

The lack of these features on other platforms do not make them “insecure” but we certainly took the opportunity to make core improvements to add additional layers of security.

Thanks for the information Paul. Not gonna lie, if there was a migration utility, I would invest the $70 for a more secure hub.

Can the V3 HUB be on both wired network and wifi? It would be awesome if I can have it wired into my network (and if it goes down) it can connect to a mobile hotspot over wifi…so basically cellular backup.

See discussion of new Wifi feature used to connect hub to internet. Can it also we used to integrate wifi-based switches and outlets?

Isn’t WEMO wifi based and is supported already? They are connected through your home network anyway, wired or wireless.

I think it’s the difference between local and cloud execution. With Wifi built in the execution can be local, otherwise it has to be cloud to cloud

No, not exactly. I have plenty of WiFi connected devices that could have local execution if ST allowed me to run my custom device handlers and apps on my v2 hub. They work great connected via WiFi to my Cat5 connected Hubitat hub, with everything running locally! :wink:

The WiFi in this new hub is most likely only there to allow users to place the hub conveniently in their home, without needing a Cat5 connection. I strongly doubt the hub will support WiFi Direct connections from client devices or even your phone’s ST App. WiFi devices and this new hub will connect to your home’s WiFi Router.

A WiFi connected device is not different than a hardwired connected device from the perspective of the hub. They are both LAN connected devices. For example, the Philips Hue bridge is actually discovered by the hub as a LAN device, and does not need cloud to cloud communications to work.

Honestly, I don’t see any advantage of 2018 hub over Connect Home, particularly when it is running in mesh network.

If nothing else Samsung have got everybody speculating about what the new hub will or will not do.
TBH I’m sick of it already. :wink:

I have a Synology router (RT1900/2600) at home and it can failover automatically to a USB dongle (Cellular dongle).
If the main WAN is cut, the dongle kicks in automatically !.
