Scene are not working in Zigbee Light Fan Switch
Device Information
Device Type: Zigbee Light + Fan
Product ID (PID): 1dacqtcg
Virtual ID : d7c931d4634d14276cqzgp
Supported Clusters: Proprietary Tuya Clusters 0xEF00 and 0xEE00
Current Status
The device operates correctly under normal conditions. On/Off and control functions for both the fan and light are working as intended.
Issue Observed
When scenes are created for this device via the Smart Life app (e.g., creating a scene that switches the fan entity to Off), the Scene Table shows the following anomaly:
The extension_field value in the scene record is generated with length = 0.
This indicates that no device-specific attribute data is being stored in the scene extension field, even though a control action (fan switch = off) was part of the scene creation.

Technical Observation: Scene Table Behavior for Tuya-Based Zigbee Device
Device
Type: Zigbee Light + Fan
PID: 1dacqtcg
Supported Clusters: Proprietary Tuya clusters 0xEF00 and 0xEE00 (no standard fan/light clusters such as 0x0101 present)
Issue Description
When defining and storing a scene (e.g., “Fan Off” state) using the Smart Life app, the Zigbee scene table shows an unexpected cluster entry:
The scene record includes cluster 0x0101 (Fan Control), even though this cluster is not supported by the device.
The extension field length for 0x0101 is always 0, resulting in:
Cluster: 0x0101
