           {
                      module: 'MMM-Temperature-Humidity',
                      position: 'bottom_bar',
                      config: {
                        var dht = new rpiDhtSensor.DHT11(21);
      	    }
            },

        No, you need to edit the file node_helper.js in the modules folder
        Currently you cannot define the pin and the sensor type in the config section. But I think this should be improved in a future release

          @yawns so i left the config.js file like that?

            {
                   module: 'MMM-Temperature-Humidity',
                    position: 'top_right',
                    config: {
                         ...
                }
            }

            I never played around with this module. But I would use this:

            { module: 'MMM-Temperature-Humidity', position: 'top_right' }

            And then you edit node_helper.js to set for DHT11 or DHT22 and the correct pin in ( )

                @H3L1o150 currently, to define the pin to which sensor is connected, you need to edit the node_helper.js file ind MMM-Temperature-Humidity directory and edit line number 12.
                var dht = new rpiDhtSensor.DHT11(2); to var dht = new rpiDhtSensor.DHT11(21);

                you can leave the config as

                            {
                			module: 'MMM-Temperature-Humidity',
                			position: 'bottom_right',
                			config: {
                				refreshInterval: 10000,
                				temperaturePrefix: "Room temperature: ",
                				temperatureSuffix: "°C",
                				humidityPrefix: "Humidity: ",
                				humiditySuffix: "%"
                			}
                		},
                

                guess this needs to be improved in future release… :D

                    i found MMM cannot auto startup if use it. because it must be run with sudo. but i don’t know how to run sudo with ‘DISPLAY=:0’? @psk

                        @jsyzthz Unfortunately neither did I have any luck executing with sudo while using ‘DISPLAY=:0’ .

                        For auto start I used PM2.

                        This is my mm.sh file

                        cd ~/MagicMirror
                        DISPLAY=:0 sudo npm start
                        

                        P.S : I haven’t yet tried this alternative by Bangee. But it sure looks promising in this scenario where we need the mirror to start from ssh(or Terminal) while specifying the display device.

                        If i come across any workarounds, I’ll update.
                        Cheers.
