One thing I haven't seen directly confirmed - can you pair w/out security using a Z-Wave 700 series secondary controller, or do you have to have a 500 to avoid security?
I just re-paired my sensors to verify my process. Here were the exact steps:
- Include the Z-Stick (mine is the Homeseer SmartStick+) as a secondary controller using PC Controller software (I'm using version 5.39). When including to Hubitat include in unsecured mode (uncheck any security boxes that Hubitat prompts)
- In the PC Controller software click on the secondary controller line.
- Click the 'Add' button.
- Push the button on the ZSE40 2-3 times to wake it up and get into inclusion mode. (Have the logging screen open and you will see activity including an 'Add Node completed' message)
- Go back to the Z-Wave details page in Hubitat and check to see that it's there. There should be "None" in the Security column.

Here it is: Z-Wave Embedded SDK - Silicon Labs. You have to sign up for an account to download the software. You also need to have a USB Z-Wave stick of some sort. As I said I have the HomeSeer version. Amazon has several that work fine. Nortek, Zooz, Aeotec, etc.

I found that but i didn't think it was correct so thanks 
. I'm assuming i download the embedded SDK then PC controller?
Just PC Controller is needed to work with the USB stick. If you need more info on how to get the secondary set up, the directions in this post are pretty thorough

@agnes.zooz Ignorant question on my part... But, would it be possible to add S2 support to the existing HW?... I mean if it's "just" FW, 1's and 0's right? Should be easy enough 
We'll definitely consider it. That may require recertification which will affect the product price but we're not ruling this out. I'll post here if we end up introducing a new firmware version for S2.

seems like a lot of work to pair in non s0 mode. i tried in hubitat no choice .. so or hit the hiway.. anyway i am scrapping mine for this reason
Another vote for S2 support for the ZSE40 v2! Sure wish I'd found this thread before purchasing 4 of them... days of agonizing over poor mesh performance finally pointed to the ZSE40s. Fun fact: if you include more than 2 of these units in a network with 40+ devices your HE z-wave radio will simply quit working! Full radio reset is the only thing that brings it back.
Putting my ZSE40s in storage in the hopes that a FW update will be made available.

Had mine paired without security and it still took down my network with a storm of repeating messages.

I'm about at my last try with these. I have 4 of them I was using on ST and every time I get to the 3rd one set up on Huibitat all my Zwave switches stop working. I've already ordered a zwave stick to try the no security work around. While waiting for it I decided to try again adding them with the default S0. Everything had been working fine for a couple days, One added, all still working, 2 added, still working. 3rd added boom all zwave switches not responding again. I can see status changes when you turn them on and off and I can see motion activation but the switches no longer respond to commands.
Removing the 4 in 1s again. I'll try one more time once the zwave stick arrives and if they bring everything down again they go in a box and I'll order something else.
(Just removed 2 and everything starts working again with only one connected.)
(Also note it is not a bad device because I've done them in different orders each attempt.)
I swapped mine out for some Fibaro motion sensors. They do illuminance, motion, and temperature, which is really all I need. They work well, and the cats-eye blinks can be disabled (not popular in my house).
I just bought a Fibaro and like it, too! Do note that if you're trying to avoid S0, it's the only security these devices support, and as far as I can tell they (like the Zooz but unlike some others) don't have a separate pairing procedure for S0 vs. non-secure pairing. So, you'll still need the stick or some other workaround to avoid that here. But aside from the usual S0 overhead, I'm not saying it will cause the same problems you may have seen on other devices.

I have 4 of the Fibaro motion sensors connected with S0 and it's been fine... not as chatty as the Zooz and my mesh has been very stable.
Thanks for the recommendations. I wish the Dome motion sensors were still around. I have 3 of those that just plain work.
One option I really like is the NYCE ceiling mounted motion sensor. It does motion, temp, humidity, and doesn't look offensive. It's Zigbee and super-fast. The downside is the very high price... I could only bring myself to get 2.

Me too! They must have been discontinued, since I can't find them anywhere (except The Smartest House had a small number of refurbished ones a few weeks back that sold out). They were reasonably fast for a Z-Wave sensor (not exactly a meaningful achievement, but still notable...) and reported usable lux values, one of which I'm using to tie into rules for my mode changes (eventually going to write an app to get all my mode stuff in one place, but that's another story).
But the good news is that the Fibaro motion sensor is very similar. From pictures, I almost wondered if they were the same OEM/whitelabel device. They're not quite, but they're pretty close: around the same size in nearly identical round cases (Fibaro's is just smoother and shiner rather than intended) and with a different mount (Fibaro uses the latching C-shaped mount, whereas Dome has the magnet with the round surface you can move/adjust the sensor around on, but both allow nearly as much flexibility--and the Fibaro doesn't stick out as much this way). The Fibaro, of course, also does temperature. Its lux readings seem to be a bit higher than the Dome for me, even when pointed at the same location, and the max readings for me (bright sunlight) seem to be about twice as high, but it's equally usable. It's a bit more expensive, but I guess I'm willing to pay that now that Dome isn't an option.
tl;dr Fibaro also good. 
I got my zwave stick today and was able to add all 4 of them and still have everything work. First time I've been able to achieve that.
A couple additions to the instructions in this thread for adding them without S0. First the PC Controller software no longer appears to be available for separate download. You now have to download Simplicity Studio 5. Once it downloads you choose to install by technology and select zwave.
Once it installs you select "tools" and you'll find PC Controller under that.
One of the posts say to click "add" to add without S0. For me that still added with S0. Instead select NWI and wait until it fully adds in Hubitat before hitting abort to stop the NWI. This got them added with none for security.

Good job!! You can also use the secondary controller to update the firmware as well. I think it's a bit faster than the HE method.
