How would I control some stepper motors with your code and the esp8266 nodemcu board. My steppers are very small and I’m hoping to control them without using a motor shield. Can I use MQTT to send the correct commands?

Hi techiesms, what a great project! It works properly. I would like to setup a MQTT project with one ESP32 as a subscriber and another ESP32 as publisher. The broker should be a local RasPi standalone as Broker-Server creating its own WLAN without connection to the Internet via Router or Access Point. Can you give me hints how to do this? The handling of the ESP32 should be easy. But with the RasPi I have got my problems to combine the installed Mosquitto and the WLAN-Server capabilities. Do you have this setup described in one of your courses? (Please without NodeRed.) Thanks! Oli

hi, can I command relays also when my phone are disconnected to my wifi? or it work only in local, when all is connected to wifi?

Great video. Just one question, how can I run MQTT server script on pi and listen to some of the data flowing on the same pi and take action against it. For example, the temperature sensor data can be used to turn on the fan connected via relays to Raspberry Pi. Also had a doubt regarding the port number. There must be some file you ran for a broker on PI? Can you please elaborate on that?

Sir, could you please consider making a tutorial/video to control these relays with the raspberry pi but using the Arduino Iot Cloud and the API they provide for the mqqt broquer exchange

Great Explanation!! If we consider real time scenario and if we are making a product then how are we gonna connect esp32's acting as a subscriber to the Raspberry PI acting as MQTT broker, as the esp32 code can't be updated again and again when IP address of broker change, can you please clarify this doubt and mobile app will be interacting with the MQTT broker as publisher to MQTT broker, Thanks in advance...
