GE Zwave Dual Control Dimmer 28175


#1

Has anyone been able to get independent controls to work on a GE 28175?

It should be possible, but I think someone would need to write a custom device handler to expose both outlets for independent control. Not sure if anybody has yet.

The endpoints should be exposed to ST. Then use this app to create the virtual switches and keep them in sync.

It would be much better to use a Composite Device Handler design, which is a Parent / Child set of Device Handlers. This eliminates any SmartApp in the solution and follows the preferred ST Architecture for Device Handlers.

Take a look at how ST added support for this multi-outlet power strip.

I remember trying this method out. In particular with the Zooz Zen20. I ended up loosing functionality vs gaining.

I believe that you stated then that there just needed to be some modifications in the code to allow the master switch and the 5 sub switches to all read as separate devices in the ST app.

Either way, I have a total of 6 power strips and I use the linked app for all of them and it works pretty darn good. But you are right, we should all try to simplify things as much as possible.

What’s the best way to start learning about working with device handlers?

Had anyone made progress on a composite device for this?

Eric,
I tried using your Dual Relay Switch to control the GE 28175 Plug-in Dual Dimmer Switch, but when I try to add the virtual devices it is telling me:
“Device Handler: Dimmer Switch Detected
Number of Endpoints: 0 Recommended Type: Dimmer”

Is there a different Device Handler that can be plugged in with your SmartApp to control this device?

Hmmm, no one has made a composite device handler yet?

My SmartApp was written before child / parent handlers were a thing. It will only work if the device handler you are using is written a certain way.
