Color State Not Updating in Real-Time on Google Home Control Page

[chris63]

We are currently experiencing an issue with color state feedback. Our application has been successfully linked to Google Home. After we modify the color of the device through our app, we notice that Google Home does not update the color in real-time.

Specifically, when we are on the device control page in the Google Home app, the color does not reflect the updated value. Only after we exit the control page, return to the device list, and then re-enter the control page, does the updated color appear.

Could you please help us understand what is causing this issue?

Screenshot of the control page:

Here is the device state we reported after modifying the color:
{

We have discovered another issue related to color temperature feedback.

When we adjust the device’s color temperature via our application, the updated value does not reflect on iOS devices, while it does show on Android devices. However, even on Android, the color temperature only updates after exiting the device list and re-entering the control page—it does not refresh in real time.

Here is the device state report we send after adjusting the color temperature:

{ "agentUserId": "8604088730de499ba33cd2cc376f49b7", "payload": { "devices": { "states": { "e9fd8b0901164b73b1bd2f1410f9820c": { "brightness": 100, "color": { "temperatureK": 4000 }, "online": true, "on": true } } } }, "requestId": "cm9ib3Qt-ZGV2aWNlQXR0cg==-8385880033093315" }

Could you please help us understand why the color temperature does not update in real time, especially on iOS?
