Ok…there is another post above that may help as well…again, let me know your results as I can certainly put in some code to get this to work.
Also, here is the linear device…it is inexpensive and works great.https://www.amazon.com/GoControl-Linear-GD00Z-4-Z-Wave-Controller/dp/B00M75TEIU/ref=sr_1_3?ie=UTF8&qid=1506980696&sr=8-3&keywords=linear+garage
Oh, neat. That is a nicely packaged solution, and would have even been cheaper than what I ended up doing with the two-device solution. Not sure I want to splurge on a replacement for it just yet, though - if I can’t make this work in software I’ll reconsider that. 
Thanks for sharing!
Hey, another thing. I just noticed that it looks like I might have installed your Ask Alexa app from source rather than a Git repo. So I imagine it’s pretty outdated. Header of the file says the following:
Version 2.1.9a - 11/20/16 Copyright © 2016 Michael Struck
Is there a repo I can update from?
Ouch…you ARE out of date…I have added a lot since then…I actually recommend you follow the direction to start over. If you have a lot of items already set up I think a PM would be a better way to go through an upgrade if you want to retain some items without orphaning others.
Hey, thanks for the tips here. I tried this but it doesn’t seem to be what I want…
Maybe I’m not thinking 4th dimensionally (I have a really hard time with that, Doc) - but after installing that DTH and SmartApp, it seems that it’s just a way to link a switch to a sensor, but I’m not sure how that helps me out. Plus, since it’s a SmartThings Multi-sensor, it now reads “open” no matter what since it’s set up in garage door mode, so no magnetic contact - rather it’s supposed to be in a vertical-vs-horizontal configuration to sense open vs closed.
So, that doesn’t seem to do what I’m after unless I’ve missed something else
ok…have you decided yet on if you are purchasing the full unit? If not I can put it on my list to create a sort of integration within Ask Alexa.
I think it would be awesome to see it there - but it’s not like an urgent ask or anything!
I already mapped out how to do it…but not sure when I will implement it.
Did some research…see this:New smart app to link the virtual/simulated garage door device with two actual devices
Should allow it to work with Ask Alexa…you will need to also search virtual garage door…read through the thread.
I actually set up this one: Ridiculously Simple Virtual Garage Door
And enabled it in Ask Alexa with no trouble at all. Worked perfectly! Thank you for your guidance today, it was much appreciated and very helpful
Exact same problem as you. I’m trying to get this set up. Can you help?
What garage door opener are you using?
In your Things tab, does the garage door show an On & Off button?
If it shows the On & Off then you can do this…
In the Amazon Alexa app set up a Routine:
When Alexa hears: Open the garage door
Alexa will: Turn on garage door
Create a second one:
When Alexa hears: Close the garage door
Alexa will: Turn off the garage door
I’ve been using this for a long time and it works perfectly.
Also, if you are using EchoSistant you can do the same thing.
Thanks.
I already have this working. I’m using an LFM-20 relay switch, set as a Virtual Momentary Switch in the ST IDE. So, when it triggers, it turns on and off again. This opens the garage door. The next time it triggers it turns on and off again. This closes the door. Have the exact thing you suggested also set up in Alexa.
However, I want it to work where the door will only open/close after checking the door’s position. I have a contact switch on the garage door which will tell me if it’s open or closed. I want to set it where I can arrive home, for instance, and if the door is closed, it will open. If it’s already open, it does nothing.
Currently, if I arrived home, the door will simply change states.
This Ridiculously Simple Virtual Garage Door purports to do exactly what I’m wanting, but I"m having trouble setting it up. Any help?
Thanks.

This is able to be done with a piston in WebCoRE.
Just have it check the state of the garage door
If: someone arrives
Do: open the garage door
Only if: garage is closed
Hey, I got the Ridiculously Simple Virtual Garage Door working. 
Seems to do everything I need, except I think I need to install the Ask Alexa smart app to tell Alexa to open/close the door rather than “turn on/off”
