Can i control an esp32 connected to my home wifi using MQTT server of any broker and pass a command to esp32 like "0" or "1"? Brokers like adafruit.io or eclipse.io.
I am using esp-idf for my project.

Yes, as long as your ESP32 MQTT client can 'see' the broker & you set an appropriate QOS then your ESP may register an interest in a value and then see changes to that value.
