I recently bought a Color (v2) bulb and connected it to my account. In the Yeelight App, I can pick white colors from the “Sun” tab, and colorful choices from the “Color” tab. However, using Alexa, I can ask for colors (set [name] to red) but not shades of white (set [name] to warm white). When I ask for a white color, I get a response “that only works when your light is set to a shade of white”.
If it matters, I’m connected to Singapore, Amazon US, and my bulb is running firmware 1.4.2_0033
