Google Home device display unavailable

[Martians]

Encountered a technical issue while developing Google Action. I have chosen a device that supports Google Home. Why is it that when I click on the device, sometimes it can display the operation normally, sometimes it is not available, and I have not received a Query Intent

Hello @Martians ,

• The reason for your smart home device behaving unexpectedly could be due to too many devices being connected to the same wifi network. Network might be dropping occasionally.
• One reason attributing the delay in command execution and other irregularities could be due to resources getting overloaded such as having a lot many devices which your router can support. 
• If the device is not able to report the state properly Google Home App will show the device state as unavailable.

Hello, I guess the reason should be that the report was not correct.

But I have a question, when should I report the status? Currently, according to the document, I report the status when the device status changes, but there is still an issue with the device being unavailable. May I ask if I need to report the status at the same time as Query Intent? Or do we need to report the status regularly?
