A variety of factors can affect the response time of the smart devices in your unit. We're constantly optimizing and streamlining to ensure the fastest responses times possible.
Your phone doesn't communicate directly with the device. When you make it a request, the instructions actually pass through a variety of services on its way to your light, lock, thermostat, or other device. Naturally, that communication can be affected by several factors, including network traffic, weather, mobile traffic, etc. (many of which are out of our control).
Our team is continually evaluating responses times and looking for ways to optimize performance to provide the best experience possible. If you're having any specific issues, please feel free to submit a support request so we can look into it.
