Acceptable latency for Google Home Integrations

[Shivanshu_Leafi]

Hello,

We have an Google Home integration with our devices but sometimes when giving Google a command it returns "Could not find device". I'm wondering what is the expected/acceptable time to get back a response from our backend system? Anything else I should look into to resolve this issue?

Google's Smart Home platform has specific latency expectations for your backend system. According to Google Home Developer documentation:

• Ideal latency: Less than 200ms.

• Acceptable latency: Between 2-5 seconds.

• If latency is consistently around 5 seconds, it's a strong indicator of an issue.

Specifically, for SYNC requests (when Google Home is trying to discover or re-sync your devices), you should aim to respond within 5 seconds. If your backend takes longer than these thresholds, Google Home might time out and report that it "Could not find device."

Thank you for the response! Just wondering, is the expectation same for `EXECUTE` requests?
