I currently have the Aeotec v3 hub, I only have thread and zigbee or cloud devices, no zwave.
I think I’ll probably upgrade to the new hub if it gets me out of the hub running at soft limit, and maybe performs a bit snappier too.
If I move to the new hub and still keep the v3 hub online can I use it for anything much more than a repeater? If I add some devices to v3 and the rest to v4 will the routines/automations for them run on v3 or v4 hub, even if all devices in the routine are only on the v3 hub?
I do have Z-Wave; 5 light switches, 3 motion sensors and an Aeotec Nanomote Quad.
When the time comes I would have to replace all of them and I would upgrade the V3 to V4 and not keep the V3.
Routines for devices installed exclusively on the v3 will run on the v3.
Routines for devices installed exclusively on the v4 will run on the v4.
Routines involving some devices installed on the v3 and some devices on the v4 will run in the cloud.
Of course any routines involving c2c devices will run in the cloud.

So for those who have zwave devices could they reinstall them on the v3 and run everything else on v4. I appreciate it’s not ideal but would maybe be a compromise for those wishing to keep zwave devices and still avail of v4 hub.
That should work.

Some interesting information from the Samsung Korea ST Hub V4 page.
**If you are an existing V3 Hub user,
you can upgrade without worry.**
Sensors can be moved automatically, and hubs can be grouped to complement each other.

I just don’t understand why Samsung would abandon all the Z-Wave users. Are they being paid by other networks to drop Z-Wave? I just looked at my list and I have 10 or 12 Z-Wave devices, including my very important garage door openers. Oh well.

They already did with the previous SmartThings Station, which didn’t have zwave either.
Samsung did Say at that time that Zwave was not on their future roadmap. They didn’t give a specific reason but most companies at the time were talking about the need to reduce customer service cost, and consumer confusion. so they were hoping Matter would help with that. And at the present time, no one is implementing zwave with matter, although technically there are some options that could allow that. But it’s a lot harder than with an IP based protocol.
On top of that, Z wave has the issue that it uses different frequencies in different regions. That has led to issues in the past with people buying devices which were not compatible with the hub that they had.
I think it really is as simple as Samsung having decided that they don’t need to support the extra costs that Zwave brings.

It is a pity that they decided against Z-wave. Maybe, the thinking was that there will be Z-wave matter bridges in future, which would facilitate integration with SmartThings.
Z-wave is not going away and is a more robust solution for security and monitoring and long range requirements, especially for larger businesses. With SmartThings Pro, aimed at businesses, I cannot imagine that SmartThings would think that there will be no Z-wave solutions in the fold. I assume that SmartThings pro is a cloud based solution and they would rather encourage Cloud based integrations from Solution providers but I see they are marketing the new hub as SmartThings pro compatible.

Hope nobody buys it for lack of Z-wave to teach them to actually support a major thing people want. If my V3 drops dead like my V2 did, off to Hubbitat.
Insanely having to replace my Z-wave switches would be worse in general because most of the light thread/matter switches are WPA2 only, even to this day. Boooooo Samssung really, c’mon what is this.

I would never use anything other than Z-wave devices for smoke and CO detection and other perimeter security sensors. I am already integrating non compatible wifi devices to SmartThings via the Home Assistant Matter bridge and will just move my Z-wave devices to HA when the time comes. It’s just a pain to have to go through re-paring everything again.

WPA2 is a security protocol for WiFi, doesn’t apply to Thread.
WPA3 is mandatory since 2020 for certified WiFi devices and Matter certification also requires a WiFi certification so most Matter over WiFi devices should support WPA3. All my WiZ and Tapo Matter products support WPA3.

I really hope zwave will be supported through the usb port or I guess my days with smartthings are going to end. I have way too many zwave devices, 5 schlage locks, and maybe 15 inoveli red switches. Makes more sense to just go to homeassistant then have to replace all of my devices.

ironically, this was solved by z-wave 700 series and up. But that must not have been enough to lure Samsung back to including z-wave in their hubs.
I think what @JDRoberts points out is not solved, you can change the frequency of the hub/adapter but not the frequency of the end devices. So you still have to be careful where you buy the device or, if it’s an unknown seller, where is it coming from.

The maximum number of devices that can be connected to SmartThings per location is 300.

I see you saying home assistant matter bridge. Can you elaborate on that?
I don’t know how well you know Home Assistant but there are actually 2 solutions avaliable from the HA add-on Store to expose devices, integrated with HA, as Matter devices. I am using one called “Home Assistant Hub”.
I have a few Tuya devices that I integrate to HA for local LAN control using the “Local Tuya" integration which is then exposed to SmartThings as Matter devices via the bridge Once the bridge is connected to SmartThings, one can add more devices and it automatically appear in SmartThings. I also use it in a similar manner for Xiaomi/Yeelight devices, my Boiler and Daikin AC split units. So far it has been rock solid.
