      Hello,

      I’m create my first magic mirror.
      I’ve find in the 3rd party module list a nice module with the name “MMM-temp-ds18b20”.
      My problem is that I don’t know how I can realize this. Because to practise this nice idea I need some wireless modules which send the temperature information to the Raspberry Pi.

      Maybe someone of you has do this in former times and can gave me some tips?

      thanks

        @jackyjoy123 the module and info on the sensor says it is NOT wireless

        the module doc describes how to wire the sensor to the pi

          @jackyjoy123 Hi, i wrote a Temperature (MMM-Temperature) module that supports multiple sensors. Also the data can be received via notifications or by fetching the data via tcp (with the netcat command).
          Personally i use an HTU21 and BME280 sensors connected to ESP32 and ESP8266 boards. The data will be send to my MQTT Bridge (Mosquitto installed on the same Pi as the mirror). With help of the MMM-MQTTbridge module the values send via MQTT will be translated to notifications which will be send to my module.
          One of my sensors is powerd by a small battery thats why i use the deep sleep mode of the ESP8266 board and only send new values all 10 minutes others are powerd by permanently and send data every 10 seconds.
          All my sketches and some configs are included in the examples directory of the module.
