    @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 everything worked, you just forgot to add the “80” here:
        f9b2ea9b-634b-484f-86d7-cfd3e04248ca-image.png

        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:
        a7b7719e-9a73-4c45-8a3e-239acb3611d5-image.png

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

          @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

              @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.
