Hi there,
I have installed MMM-LocalTemperature from glitch452 with DHT22, only the title is displayed.
Conditions:
RPI 3 B+
Raspbian GNU/Linux 10 (buster)
MM² version : “version”: “2.13.0”,
Module version : 1.3.0 the upto date on November 2020
config.js:
{
module: “MMM-LocalTemperature”,
position: “top_right”, // Only add a position if you want this module to display the data
header: “Salle de Bain”,
config: {
pinScheme:"BCMv2",
sensorPin: 6, // 22, For GPIO 22
units: "metric",
iconView: true,
initialLoadDelay: 3,
updateInterval: 0.5,
}
},
DHT22 physical connctions:
The probe is loaded with a 10KOhm
supplied with the 5V and Grnd
Data connected to pin 31 of RPI Board
Note that the probe DHT22 is properly working.
I can test it with .js script and when MM² is not launched, the answer to request are instantanelty displayed :
pi@raspberrypi:~/node_modules/node-dht-sensor $ node dht22-test.js
temp: 20.700000762939453°C, humidity: 59.400001525878906%
pi@raspberrypi:~/node_modules/node-dht-sensor $ node dht22-test.js
temp: 20.700000762939453°C, humidity: 59.900001525878906%
pi@raspberrypi:~/node_modules/node-dht-sensor $ node dht22-test.js
temp: 20.700000762939453°C, humidity: 59.900001525878906%
pi@raspberrypi:~/node_modules/node-dht-sensor $ node dht22-test.js
temp: 20.700000762939453°C, humidity: 59.900001525878906%
pi@raspberrypi:~/node_modules/node-dht-sensor $
Here is the js test file (with BCM 6 port cofigured = pin 31 of the RPI bord) :
var sensor = require(“node-dht-sensor”);
sensor.read(22, 6, function(err, temperature, humidity) {
if (!err) {
console.log(temp: ${temperature}°C, humidity: ${humidity}%);
}
});
Does anyone can help me ?
Others:
I tried the MMM-LocalTemperature by changing type of libraries ( “WPI”, “BOARD” but no effect
I also tried previously, with other module like MMM-DHT-Sensor on pin 7 of the borad with correct configuration. That one was able to display on MM² screen the T° and Hum, but with random getting data.
It seems, the DHT22 can be requested with js script within the 2sec min (specification of the probe), but not properly working when a MM Module requesting data are running :/
A big thanks for kind help
