I think I know! add at the end of command “\r\n” (no quotes) !!!
Yes man! That’s it! You are my hero. Thanks!

Is there any way to send a command with a tasker variable inside?
Example, something like this:
Send: {“id”:1,“method”:“set_bright”,“params”:[%bright_val,“smooth”,1000]}
From Send/Expect in Tasker? Yes, exactly as you wrote.
Yes, we have supported bright variable yet.
Thank you, I hadn’t find any reference in the documentation of send/expect. Just tried and it worked 
Is there anywhere you can find out more about using variables with Yeelight?
Thanks!
