Hi, Question: Is there an existing way to wire up a switch device like the ZME_WALLC or an Aeon Labs key fob to the vDev interface, such that you can see button presses or state changes, without it controlling an actual, physical device? I had previously assumed that the switch itself would show up in the Home Automation interface somehow and therefore in the vDev interface...but instead it seems that a switch device like this is usually (exclusively?) intended to send messages directly to other devices or perhaps "activate a scene".

Neither of those really gives me a way to see button presses, unless I hook it up to an actual switch or dimmer. At first, I thought I'd create a "Dummy Device", and make the switch control that...but since that's not a true Z-Wave device, I can't add it to the switch's association groups, naturally. And I could put a Dummy Device in a scene and have the switch activate a scene...but I don't see a way to do that either, there are no scenes in the Home Automation interface where the Dummy Devices live.

What I want to do is be able to see the button presses through the vDev API, so I can wire that up to an external interface/software and do stuff based on the button action. Is this possible? I can write a code device, but before I start from scratch I wondered if I'm missing something, or if someone else has already accomplished this.

My thought is that I would try to make a code device that would increment the value each time the button was pressed, or set its value to the current timestamp when pressed, or something like that. Then again, I'm not absolutely sure I can see the button presses even through the Z-Wave devices API, either...

Any hints?

If you want to catch events from buttons, attach a hook to vDev created for buttons and make actions depending on this.

It is not really clear what you want....

If you need to control something, just bind this vDev to a switch/dimmer suing Bind Devices or If->Else.

Note that to have vDev generated for a button you need to have SwtichControlGenerator enabled

I have a very similar problem with the wall mounted switch from Devolo . (I think it bases on the ZME-WALLC-S) I can include the device in the expert UI but it will not recognize correctly. I have to choose it manually from the device list. After doing this everything works fine and I can configure the device. Until here everything is ok.
Now comes the problem. Within the expert UI the device is shown as unknown device type 24 and within the smart home UI the device does not show up within the device list. The only thing which is shown is the battery status of the device. Therefore I know that the switch is recognized by the smart home UI. But I can’t neither configure it with the smart home UI nor am I able to use the device to connect it to a vDev device (it does not appear on the list). It does not appear within the list if I create a virtual switch for instance.
I think this is nearly the same problem S'pht'Kr has.
So has anyone solved the problem or has the same trouble?
Thanks in advanced

Unknown 24 dev problem should be fixed in recent versions (does not affect anything but correct label, so ignore it).

As for vDevs not created, you need to run SwitchControlGenerator and check box "create new vDev automatically on new events from remotes". This should autocreate vDevs.
