Hi,
I'm finally getting my items moved over from SmartThings to Hubitat. I have several of my zigbee items moved and that went fine (once I read that it helps to change zigbee channel to 20). But I have several Zwave items that I cannot seem to get to pair up. I've read through the Hubitat Zwave wiki and the individual devices as well. I also excluded them successfully from the previous hub before trying.
When I put Hubitat into pairing more for Zwave, I then press the button on the item, nothing happens. It's just never found. I've tried this for my August Lock, Aeotec 6 multi sensors, and my Iris/Centralite smart outlets. I can't get any of them to pair. I've moved the items to within a few feet and still no luck.
Any ideas for what I might do or try to get this working? I'm not sure what else to do. It's frustrating and sort of feels like a magic trick that one hopes will actually work this time. Any help would be amazing. Thanks so much!
Been a while since I made the leap from ST, but want to say that there were a few of the zwave devices that I had to factory reset and then exclude using the HE before they would pair successfully.

What country are you in? It’s possible that the Z-Wave radio is set for the wrong region, and can’t talk to your devices, or that the Z-Wave Radio is not enabled. See the Z-Wave Details page.

Check your z-wave table for ghosts (just in case) If none, shutdown your hub from the settings menu. Unplug power from Hubitat (from the wall, not the hub itself) for about 5 mins and power pack up. If your device still doesn't pair, factory reset the device and pair. (Click pair on hubitat before you do on the device)

Before trying to pair your Z Wave devices with Hubitat, make sure your old Smartthings device is turned off completely. If you have the version 2 hub like I did, it has battery powered backup, so it is not turned off until you remove the batteries as well. That may make pairing with Hubitat easier as both hubs won't be emitting the same frequency causing interference.
Then factory reset each of your Z-wave devices and start adding them one by one. Be sure to start with any mains-powered devices that are closest to the hub as they will serve as repeaters. Finally, once they are all included in the network, you can start adding the battery powered devices.
Most of my devices are Zigbee, but I am also starting to add some Z-Wave devices. My Aeotec doorbell and Schlage Connect door lock are Z-Wave devices, so adding Z-Wave repeaters and outlets makes that mesh more robust. I have a couple of new Z-wave sensors to add later today.
I just got my Hubitat a couple of weeks ago. The transition from SmartThings for the Zigbee devices overall was not that difficult. My biggest issue was that most of my lighting is controlled by Lutron Caseta and my old Caseta bridge would not work with Hubitat. Once I replaced the old Caseta bridge with the new Pro2 version, I reset each of the switches and Picos and paired them with the new bridge.
Good luck!

THANK YOU so, so much!! Seriously, I didn't realize that setting was there (I guess I thought it came with the settings for the country it was shipped to - my bad, not the hubs). When I checked, I found it was set to Australia (and I'm in the US). I looked up the Zwave specs for each country and they are entirely different spectrums that don't match up.
When I switched to the correct country (I rebooted, for good measure), I was amazed at how well it paired my Zwave devices. It is so much better than previous hubs I've used. The general exclude feature saved me, too. I have of the finicky Iris/Centralite dual band zigbee/Zwave repeater outlets. I've not had those setup correctly with the repeater working for a few years now. I couldn't get them paired again and couldn't get them excluded, no matter how hard I tried. I tried to pair them, and the first time it didn't work. So I used the general exclusion for one outlet putting that outlet in the Zwave pairing mode and it almost immediately found and excluded it. I unplugged it, plugged it back in, started the HE in Zwave pairing, put the outlet in Zwave pairing and boom - found it! I did this with each one in turn and it worked.
I'm so, so grateful for your help. It felt like something was wrong because I had less finicky devices that weren't found at all. Clearly, that setting was it. 
Thanks again so much. I'm really excited to have nearly all my devices over in Hubitat. Once I started in, the process wasn't that difficult at all.

That's an excellent suggestion! I hadn't even thought that SmartThings might be competing with the Hubitat. I don't mean this to bash ST but I'm amazed at how much better the HE is at pairing both Zigbee and Zwave (once I had it set to the right country!). It got to where I hated, hated adding things to ST because it was always like "pair MAYBE!". I literally NEVER knew when it would pair, when it would find things, I'd have to move the ST hub to a completely different location and pair any devices in less than 12 inches - often trying 3, 4, 5, 8 times to get it find the devices. Hubitat is so much less screwy to work with. It's how I originally thought smart home devices would be - and many of my sensors are several years old - so it's not the newest versions. I'm really grateful that I found it and that it's such much more stable. It's like what we all hoped ST would become - and more.
