Z-wave Plus Support

Does Smartthings / Aeotec Smart Home hubs natively support Z-Wave Plus, or are they just backwards compatible (I need the extended range.)?

For years I have been using the V2 hub, and am thinking of upgrading to a ST3 or ASH hub. Pros, Cons over each other, and also the V2 one.

Beginning with V2, all smartthings hubs with zwave are Z wave plus so you already have that.

There was just a discussion last week about the V2 vs V3 in the following thread.

V2 vs V3 hub


I read at a few places that the V2 is software compatible with Z-wave Plus, but lacks the extra transmit / receive power, hence the claimed 80 to 100ft for the V2, and 100 to 130ft for the V3! Any truth in that?

I hadn’t heard one way or the other. :thinking:

@posborne might know.

I have 87 devices connected to my V2 hub, and wondered how difficult it would be to migrate everything to the new Aeotec one if I got one?

Smartthings just recently released a new hub migration tool, which is supposed to help with exactly the situation, but some users have run into trouble, because the V3 has less memory than the V2, and it wouldn’t let them complete the migration. :man_shrugging:t2:

NEW Hub Replace Feature for SmartThings Hubs!

So it might work for you, it might not.



As JD said, it’s iffy. The only way to know for sure would be to buy one and try the Hub Replace Feature. If you encounter a memory error, you could always reset it and return it. Keep in mind that the V3 hub has half the memory and half the CPU of the V2 hub. With 87 devices, you should be fine, though. If the Hub Replace Feature works, you could always go back to the V2 if you experience performance issues by using the feature again to switch back to the V2.

I’ve done both a migration from a working hub to a different hub and a test when the original hub fails.

Hub Backup and Restore from a Dead Hub


Thanks for the info. They must be really stingy with RAM on the new hubs as it must have saved them literally a couple of cents only. I really wish they had made USB dongles for V2 hubs, for extended antennas, Thread and so on.

Did you have any issues with V3 with transferring Rooms, Scenes (I have about 20), Routines (I have about 25) and Smart Lighting (I have about 30)?


So how far is the run? Honestly with walls and trees and people and dogs and whatever. No matter what, range is reduced. Usually 1/2 to 2/3 of theoretical range. That’s why I use 25ft. between repeaters as the planning distance. I don’t change that for my 700 series plus gear as I’ve not really seen it do anything for range except make existing connections more stable.

If you’re between 25-50 ft then using plus on the hub may help. But it won’t be nearly as efficient or effective as two brand new 700 series plus smart switches parked right next to the hub repeating for you. If you’re over 50 ft. Then switching to 700 prob won’t help either. (because of noted cuts to range in real world above you’ll be out of practical range for that too.)

In that case now that st supports multiple hubs in a location just install a second hub in range of the location to cover it and call it a day.


Maybey 50 cents!

No issues at all. I posted a link to the walkthroughs in my last post. I went from a V3 to a Station and a V3 to another V3.


I thought about repeaters or a second hub, but I do not have any plugs or buildings between the distance that I need. Interestingly ZigBee does reach the distance fine (I am guessing as I have ZigBee bulbs outside my house), but I cant find a ZigBee Contact sensor that has Reed Switch and ideally AA batteries. It seems that most ZigBee contact sensors use hall effect sensors, and they will not work for what I need. On a different forum someone talked about using a ZigBee water sensor, well for the range it worked, but for one trigger (2 seconds) it literally sent hundreds of notifications. Thanks for the info though.
