Make ZFM-80 switch act like a momentary switch without a scene

I’ve read through this thread (two or three times, actually) to learn about how to get my ZFM-80 to behave as I wish. I’ve got this unit soldered into the controller on my wife’s electric blanket controller. It works fine when I turn the switch on and use a scene to wait one second and shut it off (the behavior of a momentary switch). However, the Vera UI then says that the switch is off.

It dawned on me that the documented values for Parameter 1 are only changing the behavior of the actual button on the unit, not the zwave switch (mea culpa).

So is there a way to make the switch keep track of its own state and behave in a momentary fashion? Ie: Turning it on-off (momentary press) shows as ON in the UI and turning it on-off again (another momentary press) shows as OFF in the UI.

I’m new to this and hope I’m using clear terminology to describe what I’m asking. I have a Vera Edge, if it matters.

This switch has a fail safe feature that will automatically turn it Off, as describe in its manual. To enable this feature set both the following parameters:

Set Parameter(variable) 2 one byte hex value to 1 - Timeout in minutes. AKA failsafe after 1 minute.
Set Parameter(variable) 4 one byte hex value to 0 - Turns the ZMF-80 Off after timeout(parameter 2) has expired. 1 = turn device On. 0 = turn device Off

The problem that you will face is that the fail safe feature can only be set in minutes, not seconds. So, while you should configure the fail safe feature to turn the switch Off at the shortest possible interval(one minute) for added safety, you will also still need to use a scene in order to try to get the one second turn Off that you seek.

I made up a simple Arduino nano and relay for this. Very simple code to delay 2-3 seconds upon startup, then close contacts of relay and 1 second later open contacts back up. I use it to open garage door(s).
