When I’ve had to do something similar, I use [invokeAsynchronous](https://docs.inductiveautomation.com/display/DOC81/system.util.invokeAsynchronous) like this:

```auto
# not tested in live environment - only provided as quick example of structure
def openPopupLater(sessionId, pageId):
    from time import sleep
    sleep(4)
    system.perspective.openPopup(id="DeviceReady", view="ViewToUse", sessionId=sessionId, pageId=pageId)

sessionId = self.session.props.id
pageId = self.page.pageId
# logic for resetting device goes somewhere before this line
system.util.invokeAsynchronous(openPopupLater, [sessionId, pageId])

```

It’s been explained to me that `invokeAsynchronous` is executed in its own thread, so you don’t risk blocking the current thread. As long as you’re not invoking this in a manner were you are sleeping on all available threads you should be fine.
