MMM-DHT22 : Temperature and Humidity : Undefined

Make sure to change the sensor pin to your pin

config: {
		sensorPin: 2, ← This line

My MMM-DHT-Sensor.js :

Module.register("MMM-DHT-Sensor", {

	defaults: {
		updateInterval: 60 * 60 * 1000, // Every hour.
		initialLoadDelay: 0, // No delay/
		animationSpeed: 1000, // One second.
		units: config.units, // Celsius
		relativeScale: 30,
		debug: false,
		sensorPin: 2,
		sensorType: 22

My config.js :

	{
	module: "MMM-DHT-Sensor",
	position: "top_right",
	header: "Upstairs",
	config: {
		sensorPin: 2,
		sensorType: 22,
		updateInterval: 60 * 60 * 1000,
		initialLoadDelay: 0,
		animationSpeed: 1000,
		units: "metric",
		relativeScale: 35,
		debug: false
	}
},

The following config.js snippet would match your graphic allowing for DHT-22 rather than DHT-11,

	{
	module: "MMM-DHT-Sensor",
	position: "top_right",
	header: "Upstairs",
	config: {
		sensorPin: 20, // use BCM/GPIO numbering, not physical Pin # or wiringPi. 
		sensorType: 22,
		updateInterval: 60 * 60 * 1000,
		initialLoadDelay: 0,
		animationSpeed: 1000,
		units: "metric",
		relativeScale: 35,
		debug: false
	}
},

I do this in first and i retry now but it’s always display “loading sensor data”, then i modify sensorPin: 20,in the MMM-DHT-Sensor.js because it stayed code_sensorPin: 20, but the problem stay here…
I even connected DHT22 directly to my raspi (GND in pin 6 and VCC in pin 4)
it’s annoying because it sounds simple …

my DHT22 would it be broken, how to know it …

@RIKKO14 First things first.

1. Check your pinout according to http://pinout.xyz
2. make sure you installed exactly to their instructions.
3. reboot after install.

I remove MMM-DHT Sensor, MMM-DHT22 and MMM-dht22, I did not removel node-dht-sensor because I don’t know how to remove, I reinstall MMM-DHT Sensor, I left in GPIO 2 (3) not to change the config.js and the MMM-DHT-Sensor.js, it does not work either, after several relaunch of MM, it worked one time but after a relaunch again it does not work anymore. .
It’s crazy, I ordered a new DHT22 because it may be defective …
