Help adjusting ramp speed on light switch (GE Embrighten)

I have a GE Enbrighten Z-Wave Plus Smart Light Dimmer (model 14295) with a Smart Things hub. When you turn the light on it takes a couple seconds turning on (from low dim to full light). I would like it to just turn on directly to the previously used dim setting and not fade on (or off).

I read something about using the Sharp Tools manager to do this, but I cant seem to get that to work. Whats the best way to change the ramp rate such that the light turns on and off instantaneously instead of ramping on or off?


I’m not sure which DTH that device is using, but if there is adjustable settings, you can access it by clicking on the device in ST, clicking the 3 dots in the top right corner, and then selecting settings. If there is nothing there, you can try using this DTH and trying it that way.

Yea I checked the three dot settings before and nothing there. I’d like to try the “DTH” but I dont even know what DTH stand for :slight_smile: This is my first attempt at anything outside of the app. Any chance you’d be willing to point me in the right direction for what exactly Im supposed to do with it? Thank you so much!

Edit: I learned that DTH is a Device Handler and I figured out how to log into the IDE and get to the “Add Device Handler” section and add this code. Now what?! :slight_smile:

You’re well on your way! You’re going to want to copy the code for the device handler from the GitHub page, then in IDE, click the menu button, click Device Handlers, click Create New Device Handler, then select From Code. Paste in the code you copied, and hit create. Then go into your devices, select the ge switch, click edit, click the drop down for Type and scroll all the way to the bottom and the very last device handler on the list should say ge jasco zwave plus dimmer switch. Select that and save. And then you should be able to go into the device in the ST app and follow the steps from my previous post and find all the features now exposed. Here’s the FAQ that goes a lot more in detail for you:

Thanks so much Andrew! So I did that but here is what I see when I hit edit in the Smart Things App. I added the “ramp rate” in there because I thought I was just titling something but now I’m not so sure what I was supposed to be doing there and now I can seem to figure out how to delete it. I will read through that link you shared and try to figure it out myself, but figured I’d go ahead and follow up here too in case you had an easy next step for me. Thanks !

You should be leaving that blank and Off. Are those the only settings you see?

They are. I was previously in the new Smart Things app but went back to the classic app and was able to edit that spot and return it to blank and I can also see that I have more options (related to this DTH) but dont see any way to edit any further to associate commands with those additional options.

Options to change the dimming steps and delay (config parameters 7-12) from the main page.

Sorry I’m not following. You’re being so awesome and patient though so feel free to drop off if you cant spend anymore time on this, but I’m not not sure I understand which “main page” you’re referring to. Thanks

Zwave devices (which your switch is) have a set of “parameters” Which can take on different values. These parameters are designed by the company that manufactures the device, and are their way of letting their customers set different options for that device.

The parameter settings are stored in the device itself and control how it functions. If ramp rate is adjustable, you will make the adjustment by changing the values for some of the parameters, however the manufacturer has designed it.

So the first thing you need to find out is what parameters that device’s manufacturer lets you set and what the different values will be for each parameter.

So you will end up with information in pairs: a parameter number, and the value that represents the option you want. The process of changing the values for the parameters is called “configuration.“

In this case, the manufacturer has a page on their website that lists all the available parameters and values. They use two parameters to control the ramp rate: One for the number of steps from off to bright and one for the amount of time the light spends at each step before moving onto the next one.

For an in wall dimmer, this is controlled with parameters 7 through 12.

( just skip the part about association groups, that doesn’t have anything to do with what you are working with right now. You just need to find the parameters that control the ramp rate and then choose the values that will give you the end result you want. :sunglasses:)

Read the examples on the manufacturer page and it should be clear:

So once you know the pair of codes that you want to put in, like

7:1 (parameter 7, value one)
8:1 (parameter 8, value one)

Then you can enter them in whatever DTH you are using.

Different DTHs may have slightly different formats for how you put it in, but they are all trying to do the same thing: save the parameter and the value that you want for that parameter in the switch so it will produce the behavior you want to see.

Thank you so much! This makes sense, but I guess Im still confused as to where I enter that into the DTH. Is there a place in the code that I make that change? If not, where is that located? Thanks!

I’m sorry, I am quadriparetic and rely on screen readers, so I don’t work with code anymore. And the new smartthings app is not very voice-friendly. :disappointed_relieved: Someone else will need to help you with the DTH that you are using. I just thought it might all make a little more sense if you understood the concepts for configuration.

It definitely did, thank you! But just to be clear, the way I would enter the parameters in is somewhere in the code, I just need to find the right location?

Yes, exactly. I believe that’s what @saosinx88 meant by “the main page.“ That would be the first page of the DTH, from which you could select what it was that you were trying to configure. In this case, not “association groups.” But “parameters“ instead.

BTW, If all you want is just to change the ramp rate, I would suggest instead of using the custom GE DTH, just use the Z wave Tweaker. This is a special utility DTH which you can use with any mains powered Z wave device. It is only used for configuration. You temporarily assign your device to it, change the parameters to however you want them to be, then you go back to using the original DTH. Because the parameter values are saved in the switch itself, they will still be the way you change them.

It’s a very cool utility, and it also has very good documentation. If you have any further questions about it, ask in the author thread for that code and someone will help you there.

Awesome thanks! I think I might be able to figure out this tweeker out. I really just want to figure out the ramping settings so I think the tweeker will do it, but after spending hours today trying to figure out the other DTH, I think Im kind of sucked into to playing with it more and figuring out what other cool things I can do!

Thanks again for your help!

You can always use the tweaker just to set the two separate parameters and then go back to playing with the other DTH for its other functionality. :sunglasses:
