Virtual Switch that follows the state of Physical Switch

[JDRoberts]

You would install the Big Switch smartapp from the mobile app, not the IDE. It works just fine with one master and one slave, it can be one to many but doesn’t have to be.

As long as the On/Off tile is a virtual Switch that has a device ID and is recognized in your network, it should work.

However, you have to first create the virtual device so that both the physical switch and the virtual switch are known to SmartThings. Then you can slave it to the other switch using the Big Switch smartapp.

FAQ: Creating a virtual Groovy Device [OBSOLETE]

Need a FAQ for the simplest version of this: a virtual on/off switch. Maybe even two FAQs, one for why you would want one with use case examples and one step by step how to for creating one in ST. Thanks! 2023 Update Since groovy will be going away soon, so will groovy virtual switches. See the new FAQ for on the replacements: FAQ: Creating Virtual Devices Without the IDE
