Hmmm. Not really the most useful topic, is it? It’s 22 pages of back-and-forth about various products; I’d have to do quite a bit of detective work to extract what I needed from there.
Have you considered something more like a simple list, perhaps? A feature matrix?
Well, I never thought being in the UK would have any advantage!
Apparently Fibaro are global though, and it looks like it operates from 110 to 240v. The only thing remaining is type approval and frequency, I think you should see them soon enough.
Yeah, we really need a wiki. It would make all these information searches way easier. 
@ben ? Any chance of getting an officially hosted wiki? The forums are great, but they serve a different purpose.
We have looked at it. These forums can create “wiki posts” has anyone ever tried that? Not sure 
Ther GE 45631 stick-on-the-wall controller works fine - you just have to set its lighting Scenes at the switch - outside of ST.
I was looking for a battery powered z-wave input module and found this discussion.
I agree with Graham Charles totally.
Looks like no one has an answer - as there should be one!
And there is one - but why so rare I don’t know

or this might work mounted along side a conventional wall switch with the wire from it going behind the face plate into the mains free switch contacts of a conventional wall switch.

Let me know if the latter set-up could be used to generate z-wave on and off commands to z-wave power switch. I’d like to know.
Found this at Home Depot yesterday: Lutron Connected Bulb Remote
Says Wink Hub required, but the package and Lutron indicate it’s Zigbee (not on the web listing). The description says it controls Cree and GE Link bulbs directly, and the spec sheet says the same generically – I didn’t know Zigbee could do that, can someone explain how to set that up - maybe that’s what you need the Wink hub for?
Previous Lutron products used their proprietary Clear Connect system, which Wink had support for, but this one seems to just be Zigbee, so it seems like it should work with SmartThings. My current use-case is well-served by the controller I hacked together from a key-fob and mechanical buttons, but I’m tempted to get this if it can provide easier dimming control.
I am late to this thread, but couldn’t agree more with grahamcharles. This would be very useful piece of hardware since it allows people that aren’t as interested in using the apps or even Alexa to use a good old fashioned switch in an old house with no neutral.
Just basically be able to trigger a scene in ST. So keep the ideas coming cause i am still looking for a good solution to this.
There is now an official integration with smartthings and Lutron Caseta. These are wired switches that do not require a neutral. However, you will need the Lutron smartbridge as this is a cloud to cloud integration.
There’s also a Leviton zigbee wall switch which does not require a neutral and is on the official “works for SmartThings” compatibility list, but I haven’t heard of anybody actually using one and it’s an expensive switch, around $85 each. But it is another option and it doesn’t require an additional bridge device.
If you were looking for a battery powered switch to communicate with a smart bulb or a micro relay at the ceiling fixture or to create a virtual three-way with another smart switch, see the following:
So there are now several different ways to address the issue of a switch box that doesn’t have a neutral.
Just ordered one!
Ooops, missed the part about needing a Lutron smartbridge. Not a great solution still then!
Works well, people like it. One Lutron SmartBridge can handle several dozen switches. So it does meet the need for many people. It would be expensive if you only needed one switch, but once you get up to four or five it’s comparable to other choices.
