just got my Echo Plus, and a few Yeelight Bulbs (1st and 2nd gen, white and RGB).
I can pair and control the bulbs no problem with the Yeelight or the Mi Home app (iOS, iPhone 8S Plus), but when I try to connect them to Alexa / to the Alexa App. It will always tell me that there are no new devices. I enabled the Yeelight skill, and linked my Mi Account successfully. I tried different servers in the Xiaomi Apps (Singapore, USA, Germany), but to no avail.
Same issue here… I have set the yeelight on Mi home on Singapore server and they are recognized on Yeelight app. Alexa is not able to discover them… ID 1705120632.
Thank you @weiwei
