Do you mean ZSE40s? And ones that are not brand new? You will be able to pair them with a secondary controller and no security. But they won't work well. There's a possibility to still mess with your Z-Wave mesh. And drain batteries. It's not worth the hassle. You can keep them on your old hub and use the Hub Mesh app to keep on using them if you want.
The newest ZSE40s with the 700 series Z-Wave chip (just released) will work fine with the C7.
I agree with @bill.d, you want to avoid putting those on the C7. I had 3 on my C7 and that (along with some other issues) caused me some major Z-Wave headaches.
I know someone wrote up a nice guide on using the pc controller software. I think in the context of how to remove ghost nodes. I can't find it though. I also can't seem to find the actual software to download anywhere, which is weird. I'm starting to suspect it's bundled in with one of the SDKs or something.
When I get to step 7 where you select the device in the pc controller software, the software just sits there with a green bar going across saying
waiting for completed action
The version populates like your screenshot, but everything is grayed out and unclickable. I've tried it like 10 times now with the same result. I've even tried waiting about 20 minutes to see if anything will happen.
Uninstalled the device through device manager, then installed the newer driver, put zstick back in and it installed the new driver for the device. Rebooted. But I'm still stuck trying to select a source.
I actually got it working by not clicking detect and just selecting the zstick and clicking ok with the version and description being blank. I just joined it to m ycurrent C5 as a test.
Out of curiosity, before I start migrating, is there a way to see the neighbor table like what the C7 can show?
So what do we do with those apps/devices that get migrated over when transferring the database? Delete them off the new hub so they can be re-created new?
It also sounds like my Zen30s won't transfer this way since the relay is a child device.
You could keep your old hub and use that for cloud/network/mobile apps/devices.. then use HubMesh to share as needed. That's what I am doing. Lightens the load off the main hub(s) a bit.
