Hello,
What is the exact syntax to send Relay1 ON with MQTT. I am reading the document , I have my module sending State data, but cant find the right syntax to end  orders.
Thanks

which board you are using? please upload some photo, how you write your mqtt command.

I Use the 4A. Finally I read again the litterature and find the right syntax. I was confused with using the parenthesis..Thank you

ok
