Yeelight Bulb Color 1S not working with Alexa


Yesterday, I installed my yeelight color 1s 8.5 watt bulbs.

They are connected to the yeelight application, the Xiaomi Home and Yeelight skills are installed in Alexa.

I’m on the Singapore server.

But it is impossible to install the bulbs in Alexa.

What should I do?

thank you,
