Does this device work with the WD iDrive system? All the options are wirelessly connected (light, keypad, door opener,etc.)
Yes, but if there are no terminals for the wired button, you will have to use a spare wireless remote to setup Garadget (or any other aftermarket controller). See examples how it’s done with security+ 2.0 openers.
Feel free to post the pictures of the both sides of the remote’s PCB if you need help figuring out the correct connection.
