I just updated the code in GitHub. The settings are set to required but I don’t have any default values filled in. I tried it with one of my dimmers and it seems to work. You will need to update your local handler (copy and paste or Update from Repo). Let me know if this works for you.
Good work on this and Thank You for the effort!! I am installing the GE 12724 dimmer throughout my house (didn’t find out about the 14294 until after I had bulk ordered the 12724 and was too late to return 
) and was wondering if there was a way to set the default dimming level in the DH? I have some that I want to bring immediately to full bright, some that I want to start at 20%, etc. My wife hasn’t fully grasped the physical switch functions so my lighting levels are all over the place.
Thanks,
Duwayn
Unfortunately the DTH can only control the behavior of the switch when controlled by SmartThings. So it isn’t possible to have the lights always come on at 100% when turned on using the physical switch. It could be possible to update the DTH such that sending the On command from SmartThings always turns it on at 100% but it gets hard to support every possible way people want the DTH to function. I have seen people use CoRE to turn up lights when they are turned on but that always has some lag to it. The other option is to use CoRE to turn the light on to 100% and then immediately turn it off if the light is turned off while at less than 100%, this has the disadvantage of having the light flash after turning it off but does make it so it is 100% the next time it is turned on. I feel your pain on this my wife and my mother-in-law are always wanting to hold the toggle instead of tapping because of the (very brief) delay while the switch is determining if you are going to tap or hold the toggle. I wish dimmers offered a way to set the “last” level without turning the light on both for this reason and so that you can set lights to come on at a low level at night and full brightness during the day/evening.
I am looking for a way for the GE Dimmers to send to CoRE that the device was changed Physically. The default DTH doesn’t appear to be able to tell CoRE if the switch was turned on/off by the Physical Switch…
Also, not having a reference to what the stock DTH setting are, I don’t really know what to change the setting to. Is there some kind of reference chart? Or maybe put (default is “X”)…
Same here - I like the ability to customize the values but I’d like to set them all to default first and then make gradual changes.
Do you @nuttytree have a list of what the default values are? I’ve somehow lost the ramp up/down when clicking the physical switch.
Try this DTH.
Does this allow the LED to be ON all the time instead of indicating the switch status? Thank you for your hard work!
Thanks for mentioning that one!
How the LED behaves is a function of the firmware of the switch and the firmware only allows When Off, When On, and Never.
This may be a newbie question, but changing the device handler on a device is the type option correct? How do I add a custom type?
Thanks for this DTH. Worked perfectly for me. The default handler worked but I kept running into problems when I turned off my LED lights. The light flickered at anything below 15% so as the light turned off the default steps and timing made the lights flicker. I went into the custom DTH and changed those values to “1” and it works amazing now. Thanks again for your work on this!
Does this have the ability to to keep the light on if they are turned on from the switch. I have automation but I would like to by pass it once in a while.
Thanks
I don’t understand the double tap features and how to use them. Anybody have any information on this? When I click on the double tap icon in ST nothing happens. When I double tap the actual switch nothing happens. I assumed a double tap would allow me to go full brightness or some other default level
There is no default action for double tap in these devices. You have to trap the double tap and handle it with a smart app or WebCoRE to tell the system what to do with it.
Advanced Button Controller is a good option if you want quick and easy. Use WebCoRE if you want flexibility. Whatever you use, the double taps for these switches come across as button #1 for DT up and button #2 for DT down.
thank you …
Nathan - I’ve set this as the DTH for one of my GE Zwave + switches (wasn’t sure if that was required or if the double-tap virtual buttons are supported w/the stock “Dimmer Switch” DTH), but I do not see an option to select Button 1 or Button 2 when using the switch in a piston in webCore .
What’s the missing step to enable access to the virtual buttons from the double press on this switch. (I opened up the ST Button Controller smartapp just in case, but it doesn’t see the switch as a button either.)
Thanks!
I use this DTH for my 14291’s:

this one for my 14294’s
https://community.smartthings.com/t/beta-ge-jasco-z-wave-plus-dimmer-switch-with-double-tap-associations-and-all-configuration-options
Once installed and associated, you will see the double tap buttons on the device page and Button 1 and Button 2 will show in WebCore like this:
Absolutely perfect, thanks!
Hmmm…completely odd. Last night after switching to the jasco-ge DTH I could see Button as an option in webCore for the switch.
However, this AM, even though I still see “NumberOfButtons: 2” in the IDE for the switch, webCore is back to only showing Indicator Level, Status, and Switch options, the Button option has disappeared from webCore. As Spock would say, “Curious.” 
NVM…not sure what I was smoking last night, but I went into webCore Settings and added the switch to the “Buttons” section in available switches, and now the buttons are showing up in webCore. Could have sworn I saw the buttons in webCore last night, but it was late and I’d had a beer, so who knows.
i just installed this and set up webcore to use a switch to turn on a pendant light using the switch for my recessed light, love that i can do that w/out adding another switch in the box. However something odd happens. Whenever i turn the light off, the dim level changes to some random level (34%, 66%, 72%) no rhyme or reason for it. Any idea why that would change? I turn it back up after every change and nothing seems to make it remember where it was. Any idea?
