If you are starting out and wish to have a relatively easy experience in developing your projects, then try the build-in web interface.
Example of Tasmota Web Interface
the Sonoff 4 Channel Pro MQTT Switch
For the temperature/humidity monitor, you also need to specify the sensor type, e.g. AM2301.
You use the Tasmota WEB UI for configuration. Enable MQTT in "Configuration/Other" and then specify your setup in "Configuration/MQTT".
