Required attributes for NetworkSpeedTest

[GoogleFAQ]

When implementing the NetworkSpeedTest trait, is it required to also implement the networkSpeedTestInProgress error?

In order for Google Home Ecosystem to function correctly we require certain attributes and status codes to be fully implemented. When such an attribute is present, it will be marked as Required in the documentation. Even for cases the execution flow works (partially in most cases), we require this set of items during your project certification.

For NetworkSpeedTest, networkSpeedTestInProgress is marked as a required item, so you need to implement it for a fully functioning implementation.
