So do you have to use the Virtual Device Creator App to make a virtual switch local? Or will the virtual switches weā€™ve created through the IDE automatically become local? Iā€™d assume anything using the Virtual switch DTH would be local, but thatā€™s usually when I get myself in troubleā€¦ Iā€™ve seen a few references in the beta discussions, but I wasnā€™t certain how all of that would work. ---

There are two new device types that runs local, whether you create a virtual device from the app or in the IDE doesnā€™t matter. The confusion will be for years people created ā€œvirtual devicesā€ which used the ā€œsimulated switch/dimmerā€ device type. Well the new ones that run local are appropriately named ā€œvirtual switch/dimmerā€. ---

Point taken. I havenā€™t been in the IDE in a while and assumed that the dth I was using was the virtual one. (Remember what I said about getting myself in troubleā€¦ šŸ˜‚) Now, that you mention it, I do remember it being a simulated switch, not a virtual one. Good to know! Thanks! ---

@Automated_House is correct. However, one gotcha that comes from creating the device directly in the IDE is you have to specify the hub field when creating the device otherwise it wonā€™t run locally (because we donā€™t know which hub should run it). By default that field will not be filled in and itā€™s easy to miss when creating one manually. ---

Iā€™m surprised the Hub and Location fields arenā€™t required. ---

Iā€™ll also use this opportunity to share another new feature that actually just came out today: ![Screenshot_20180404-152149](https://global.discourse-cdn.com/smartthings/original/3X/f/3/f320b7de8a36c59750e488eb13f1c572aa11de4b.png) ![Screenshot_20180404-152154](https://global.discourse-cdn.com/smartthings/original/3X/1/4/14ecb805543d3ef0a76dcfbba24dd2bae003bbc9.png) You can now set a SmartLighting rule to only trigger if a switch is in a specific state. This is an added use case for the locally running virtual switches, but it can be used in the cloud, or with any other switch device as well! ---

The reason would be that there could be some cloud to cloud integrations that arenā€™t tied to any hub or location and could be used across all your SmartThings locations. ---

Ah, some good stuff in here. Excited about the local virtual switch and the SmartLighting switch condition. Kind of worried about the Z-Wave protocol update. No clue what that actually entails. . . .but makes me worried about network gremlins coming to my house on Thursday. ---

@farlicimo I will fight off any network gremlins coming your way on Thursday, a personal guarantee. ā€œNetwork gremlinsā€ is the best I have heard so far. Kianoosh ---

Very nice! Also a good time to remind people of the other new feature: mirror behavior. (apparently titled by a Canadian or UK dev šŸ˜‰ ) ![image](https://global.discourse-cdn.com/smartthings/original/3X/7/4/74d428880f354677fe1414894e75e2a8bb168e86.jpg) Are mirror and the switch restriction eligible for local execution? ---

You bet, following the same rules as anything else for local execution, if all devices participating in a rule run locally the automation will run locally as well. ---

This is awesome, this should purge more stuff from my WebCoRE. Now only if I had a V2 hub this would run local. Any chance of creating a system that will always preform a task every X minutes or seconds while a switch is on? Change Light color every minute while virtual light color change switch in on. ---

@Zach_Varberg are the Smart Lighting enhancements dependent on the hub firmware update? ---

No, they should work locally on anything after version 0.19.X of the hub, but you will be far more limited on which devices run locally on older versions of the firmware. [Next page](https://community.smartthings.com/t/hub-firmware-release-notes-21-12/124044.md?page=2)
