Google did not develop the Smart Life / Tuya integration in the Google Home app. Tuya wrote that integration using the Google Home / Google Assistant SDK.
The only public API that they have provided us 3rd parties is this tuyapy library. The status/discovery request in that library can only be sent every 10 minutes or they will throw an error. This is Tuya trying to limit 3rd parties from flooding their cloud servers with too many requests. I can understand their reasons for doing that. My wish is that they will at some point provide either an event based or local connect solution.
It would be nice if they could eventually add some APIs like ewelink / Sonoff has. For newer Sonoff devices, they’ve got a local zeroconf service that works very well. When you’re at home, this is used to listen for status changes. When away from home, an event based WebSocket is used to listen for changes.
All I’m trying to say here is, you will find some Home Remote integrations that provide status updates immediately & some that don’t. There’s usually a reason for that.
