Display different Roomtemperature on MagicMirror

[wishmaster270]

@Xilef
You will need the MMM-Temperature module and not the Embed module as you do not want to display a website but parse the JSON data object and display its contents.
The config will look something like:

		{
			module: "MMM-Temperature",
			position: "bottom_right",
			config: {
				sensors: [
					{
					    name: "ESP",
					    script: "/bin/nc",
					    args: "-w3 192.168.178.106"
                    			},
				]
			},
		},

But you will need to fix the missing sensor first.

Can you please check your wiring and use this sketch instead of the other one. I only removed one line which i do not think is the problem but i can not test the sketch at the moment.

#include <WiFi.h>
#include <Wire.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BME280.h>

const char* ssid     = "##ADD_WIFI_SSID_HERE";
const char* password = "##ADD_WIFI_PASSWORD_HERE";

//ENTER STATIC IP OF THE ESP32 BOARD HERE
IPAddress local_IP(192, 168, 0, 2);
IPAddress gateway(192, 168, 0, 1);
IPAddress subnet(255, 255, 255, 0);
IPAddress primaryDNS(192, 168, 0, 1);
IPAddress secondaryDNS(8, 8, 8, 8);

Adafruit_BME280 bme;

WiFiServer server(80);

void setup()
{
  Serial.begin(115200);

  if (!WiFi.config(local_IP, gateway, subnet, primaryDNS, secondaryDNS)) {
    Serial.println("STA Failed to configure");
  }

  Serial.print("Connecting to ");
  Serial.println(ssid);

  WiFi.begin(ssid, password);

  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }

  Serial.println("");
  Serial.println("WiFi connected!");
  Serial.print("IP address: ");
  Serial.println(WiFi.localIP());
  Serial.print("ESP Mac Address: ");
  Serial.println(WiFi.macAddress());
  Serial.print("Subnet Mask: ");
  Serial.println(WiFi.subnetMask());
  Serial.print("Gateway IP: ");
  Serial.println(WiFi.gatewayIP());
  Serial.print("DNS: ");
  Serial.println(WiFi.dnsIP());

  if (!bme.begin(0x76)) {
    Serial.println("Couldn't find sensor!");
    while (1);
  }

  server.begin();
}

void loop()
{
  float temp = bme.readTemperature();
  float tempf = temp * 1.8 + 32;
  float rel_hum = bme.readHumidity();

  WiFiClient client = server.available();
  if (client) {
    Serial.println("New Client."); 
    client.println("{");
    client.print("  \"temperature_c\": ");
    client.print(temp);
    client.println(",");
    client.print("  \"temperature_f\": ");
    client.print(tempf);
    client.println(",");
    client.print("  \"humidity\": ");
    client.print(rel_hum);
    client.println(",");
    client.println("  \"error\": false");
    client.println("}");
    client.stop();
    Serial.println("Client disconnected.");
    Serial.println("");
  }
  delay(100);
}

@wishmaster270 i connected an other sensor and it doesnt showed me the error message, i will try the sketch tomorrow, the MMM_Temperature module is installed and works, but doesnt show any data, im gona try to fix it tomorrow

[Xilef]

@wishmaster270 everything worked, you just forgot to add the “80” here:

i just set up a second sensor and cloned the module
if i go into my browser and type the two different IPs every sensor shows his own data, but the mirror displays 2times the data of sensor 2:

(sensor1: “test” | sensor2: “test2”)
how do i fix that?

[wishmaster270]

@Xilef Perfect. One step further.

You only need one instance of the module. So your config will look something like:

		{
			module: "MMM-Temperature",
			position: "middle_center",
			config: {
				sensors: [
					{
					    name: "test",
					    script: "/bin/nc",
					    args: "-w3 192.168.178.106 80"
                    			},
					{
					    name: "test2",
					    script: "/bin/nc",
					    args: "-w3 192.168.178.108 80"
                    			},
				]
			},
		},

@wishmaster270 yes, it works

and in the future i can experiment with the MMM-ValuesByNotification Module to customize the module, right?

and a big thank you for the help and the quick reply

[wishmaster270]

@Xilef Perfect.
Yes, the ValuesByNotification module is very powerful but the configuration can be get complex very quickly. You will need my other module CommandToNotification, too.
