Yeelight strip can only use blue colour now.

Yeelight strip suddenly only shows blue colour. Going through the rainbow in the yeelight app every colour only displays blue on the strip. Did the reset, only blue. Is this a firmware issue? The light itself works fine, is stuck on one colour permanently.

Can you whitelist me or something?

From your description, it seems that the lamp is damaged. Please provide the specific lamp model name and Mijia account ID.

Fixed it. The cord wasnt connected properly. Thanks team
