Everything is slow or laggy (delayed response)

We are experiencing slow and delayed responses from both the keypad and the mobile app in C-Bus. We are using a third-party app (Elan), but even after disconnecting Elan, the issue remains the same. Has anyone faced a similar issue or found the root cause?

 

Slow C-Bus is generally due to too much traffic or comms issues such as: poor terminations, poor segregation, low C-Bus voltage or too many devices on the network. Network burdens can also add to problems, as can too many or too few network clocks. Traffic should < 10 messages a second at rest.
