Yes, the LFM-20 can be used with Vera. Similar to HomeSeer diagram above the LFM-20 is installed parallel to the door switch, and can be activated via smart phone, main control, sub-controller, etc.
* * * * WARNINGS * * * * Be careful you understand this device before installing it!!
-- Warning #1 -- Remote = Danger: Remotely controlling a garage door can be a safety risk. As with all such devices, be careful not to override any safety devices like door motion reverse; bump reverse; line of sight sensor or other safety triggers. You don't want to trigger the door from 100 miles away, only to find out that Gramma or little Joey was walking under it taking out the trash and you remotely hit them on the head.
-- Warning #2 -- Ensure Device = PushButton: Take care to install a SCENE EVENT to activate/deactivate the door controller rather than expecting to control it via the LFM-20 device ON/OFF directly. Otherwise, if you end up with the LFM-20 left ON inadvertently, it can hold down the garage push button and can disable other garage push buttons, so could lock you out of your garage!!!! Not good.
Assuming you're comfortable with the risks, let's get on with doing this.
Let's now add the Scene we'll use as push button controller for LFM-20 and a state-sensing event trigger:
- Create a new Scene
o Call it DOOR.Button (or something similar)
o Add to room GARAGE (or whatever your Vera "Room" section is called)
o Click on the COMMANDS tab
o Room: GARAGE (or wherever you put it)
o When you click the Room, you should see your Device
o Choose and Check your device from the list
o Choose ON from the state drop-down
o Change the "And leave it" to "AFTER 5 SECONDS" a new drop down appears
o Choose "OFF" (you want a hard OFF here; not just go back to previous)
This forces the switch OFF anytime it is turned on by anything, including manual, console, remote, smart phone, etc.
Then it would be a good idea to add a second scene to force the "Off after 5 Seconds" in case someone forgets and triggers directly.
- Create another new Scene
o Call it DeActivate.after.5.Secs (or something similar)
o Add to room GARAGE (or whatever your Vera "Room" section is called)
o Click EVENT tab on the DOOR.Button Scene
o Click "Add Event" button
o Choose Device (Look for device you added for LFM-20. If it was the last device you added, it will be at the bottom. Hopefully you called it LFM-20 or Garage Door or something useful so you can find it here)
o Type of Event - "Device is Turned On or Off"
o Name for this Event: "Garage Door PB ON"
o Which Mode? "ON"
o ( Optional alerting on this mode... let's leave this off for now, unless you want an email every time the event triggers )
o Click Save
This scene will function as a sensor to turn OFF the device anytime it's turned on, like the "PushButton" scene does. Anytime the LFM-20 device is turned on, it will be turned OFF after 5 secs (i.e. like a pushbutton) When the scene is used on the controller module wired parallel to a door opener (or any other momentary contact type switch) it functions as a replacement for that push button.
