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
Ah … I spoke too soon!
The YLDP02YL bulbs that received the firmware update work fine. The light strip (YLDD01YL) does NOT work with “white” commands. It does, however. work correctly when used as part of a group that includes one or more of the yeelight bulbs!
So “alexa make light strip white” returns “that only works when your light is set to a shade of white”(where “light strip” is a YLDD01YL).
BUT “alexa make corner light white” works ("corner light is YLDP02YL), and “alexa make side lights white” works (“side lights” is a group of 1 x YLDP02YL and 1 x YLDD01YL.
Does the YLDD01YL require a firmware update similar to that made available to the YLDP02YLs 2 days ago?
