I have established a connection with cloudmqtt and can send messages to cloudmqtt as well but cant find any procedure to send commands from cloudmqtt to my esp. Actually i have a website deployed at heroku and i want to control my esp from there. Please help me out to send commands to my esp and carry out set of instructions.
