MMM-Temperature/Humidity Module (DHT11, DHT22 and AM2302 sensors.)

[H3L1o150]

Hi, i am really new on this, someone can help me, with the code on config.js file?

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

thanks

@H3L1o150
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 ( )

@yawns Tanks for the help

maybe i’m wrong in code. with me show a white screen

@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

Tanks @psk

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 checkt this out: https://forum.magicmirror.builders/topic/738/mmm-dht22-humidity-and-temperature-module

@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.
