Hub V2 and a new home


Long term V2 Hub owner, and now moved house. I lived a set and forget attitude to smart homes. I built the thing years ago and never really looked back - until I moved.

Now I’m in a different country and in a bigger concrete house. My hub alone isn’t going to cut it.

I’ve read there’s new tech these days with Thread and Matter. And I’ve also seen new competition with Aqara and Homey.

I wanted to know of any thoughts on how to bring my V2 into the new era - or if I should just bin it off and get a cheaper Aqara hub?

As you can imagine, nothing works here, signal is too weak to make it out of the concrete room the hub lives in.

tldr - Do I have matter and thread? Is v2 dead? how can I extend the signal of my hub? I like Aqara

The issue you have isn’t the hub, regardless of brand. Your issue will be adding as many zigbee/zwave/matter/etc. routing capable devices to your mesh to make it strong. I have a large home, and my v2 hub was most recently at the furthest corner of the house inside a cabinet with a mirror in front of it. It was also far away from any wifi router or access point.

I never had Zigbee/Zwave mesh issues until I started to reduce my Zwave devices. I eventually got to the point where my last two Zwave devices were so far away from the hub that they stopped responding. All I did was relocate the hub closer to those Zwave devices and they started communicating again. I did have to rebuild my Zigbee mesh, but to this day I’ve not had a Zigbee mesh issue since the hub was moved.

tldr; You need more devices that can route the bigger your house gets.


The V2 hub is a matter controller, but not a thread border router. So with just the V2 hub, you can use matter over Wi-Fi devices. If you also want to add matter over thread devices, you would also have to add a thread border router, but there are many of those these days, including some of the Amazon echo models, the HomePod mini, and some of the Google home devices. So you may already have one. :sunglasses:

FAQ: What do I need to add a Matter device to the SmartThings app? Do I need a bridge router device?

Is v2 dead?

It’s not being manufactured anymore, but it’s still a very popular hub, and in fact has more memory than the newer hubs. Most people who currently have them are keeping them.

Yeah, concrete buildings are always a challenge. But the advantage of both Zigbee and thread is that they are “mesh networks“ which means pretty much any mains powered device can pass along messages from other main powered devices of the same protocol. So you pass the messages along rather than making the hub do all the work.

In the case of Zigbee, The profile that SmartThings uses can handle up to 15 hops into the hub and then another 15 out again, so that’s usually enough to get a message from one side of the house to the other although you may have to be careful about placement of the repeating devices. There are some people in concrete or Adobe houses who end up putting a hub on each floor just because it’s too hard to get signal from one floor to another, but that’s just something you have to try and see.

Start with post 11 in the following thread (I will link directly to that post), read that, then go up to the top of the thread and read down, and you should learn a lot about how to set up a strong network.

But as long as you have wooden doors or fabric curtains on the interior doorways, you’ll probably be able to make it work. If you have metal doors, it could be a problem.


I personally use both an aqara hub and a SmartThings hub right now. My aqara hub is one of the models that can act as a “matter bridge,” so it can bring many of its devices over to my SmartThings account. That way I get the best of both worlds: I get additional features and excellent reliability in the Aqara app, but I can easily use my aqara sensors in particular in my SmartThings routines. And the connection is local. So that’s another option that only recently became available. :sunglasses:

new country

If you use any Z wave devices, then, of course, there is the issue of whether you stayed in the same zwave region, but it didn’t sound like that had become an issue for you.


That’s awesome JD. Really appreciate the response.

Which Aqara hub did you get? I like the idea of running both and sharing Aqara devices into STv2 using Matter.
I’m looking at the M2 Hub… I’ve read it will act as matter bridge, but nothing on the Aqara material.

I’ve also found these little things… $6.50 each… Seems like a quick win for repeating the signal?

Thanks again

Those repeaters are probably tuya specific, they may not help you with either aqara or smartthings. You can try one and see. But you shouldn’t have to worry, there are a lot of Zigbee devices you can find that will work.

I have several aqara hubs that I use with HomeKit. The only one I’m using with SmartThings is the M2, as a matter bridge. It’s working well for me and was really easy to set up. I only set it up about 10 days ago, so I am planning to add more devices to it.

Aha! so does that write off all Tuya device, as I was next looking at these:
$7 each. I figured if I’m paying $6 then might as well add a dollar and make it more useful…

Also, love that M2 integration! ordering!

Tuya uses a LOT of proprietary code. So their devices probably won’t work out of the box with SmartThings at the time of this posting.

In the future, they have announced that they are also going to make a matter bridge like aqara has done, and in that case, you would be able to add their devices to their own hub, and then bridge them over to SmartThings via Matter, for an easy, reliable, local connection. But we aren’t there yet. So far the only tuya matter bridge which has come out is the one being sold under the zemi smart name, and it’s early days on that one still. It only supports a few models so far.

For now, you may be able to get to Tuya devices to connect directly to your SmartThings hub, but many will require custom code, and it can be a lot of trial and error to get them to work. Also, very few tuya devices have the same safety certifications as aqara or some of the other Zigbee manufacturers. They are definitely cheap, though, but sometimes that’s for a reason. :wink:
