    Hi. I bought an ESP32 module, managed to run a temperature reading from a DC18B20 sensor on it and display this on the display. In the future would like to do something more on it, connect other sensors and control relays.
    For the moment I would like to see the measured temperature remotely on a smartphone. I know this can be done using the MQTT broker, Oracle cloud, openHAB and a smartphone app. But I don't know how to go about it. Please give a hint to people who have run this before.

    I've learnt a bit and it's possible to do this without any code in the arduino or without any coding?

    How do you figure that out ? :?: :?: :?:
    You have written:

    Wasn't that the Arduino code ?

    I didn't do it in tasmot pure mouse click, all I typed was the WiFi key.

    If you are only going to work with Tasmota and not program anything yourself, then it remains only to use a ready-made application such as this one:

    And I still don't know how to move forward with the topic, I have found out yet that on the Oracle Cloud you set up a virtual machine on which you install ubuntu, make a Dashboard, somehow configure it all and I can access the readings from anywhere in the world as long as the smartphone has internet access.

    And you hope it's less complicated as an implementation using Arduino for which there are plenty of ready-made examples.
