I've tested the Color Switch Command Class with the following setup:

Setup

• EN: BRD2603A (ZGM230S) + Led Bulb (2025.6.1)
• Controller: ZGM230S + 2025.6.1 on WSL2 Ubuntu 22.04.5LTS

Tests

• Changing level of each Color id {2, 3, 4} between 0 and 255.
• Start a Up/Down Level Change for each Color id {2, 3, 4} with different duration {0, 10, 100}

Verification

• Successfully change Attribute value
• Zniffer shows commands successfully being sent and there are reports with correct state.
• Successfully change color on BRD2603A
