In general, you should see a response from your device immediately to within a few seconds. Sometimes, however, your device may take 30 seconds or longer to respond. Circumstances that may cause a delayed device response:
Network routers, baby monitors, wireless phones and even microwaves can create interference between devices
Building materials (drywall, brick, concrete, etc.) and the layout of your home may impact response times
Storing your hub inside boxes or metal enclosures may reduce performance
Moving your hub to a new location farther from your devices may negatively impact device connectivity
Rapidly pressing buttons in the app can create congestion in the system
