+# Internal Temperature Usermod
+This usermod adds the temperature readout to the Info tab and also publishes that over the topic `mcutemp` topic.
+
+## Important
+A shown temp of 53,33°C might indicate that the internal temp is not supported.
+
+ESP8266 does not have a internal temp sensor
+
+ESP32S2 seems to crash on reading the sensor -> disabled
+
+## Installation
+Add a build flag `-D USERMOD_INTERNAL_TEMPERATURE` to your `platformio.ini` (or `platformio_override.ini`).
