+## HomeServerIOExt
|
|
|
+
|
|
|
+When migrating my home control server from a Raspberry Pi to x86 hardware I needed an interface to connect some sensors (door contact, PIR sensors, temperature sensor)
|
|
|
+which were previously connected to the RPi´s GPIOs.
|
|
|
+
|
|
|
+This simple solution consists of an Arduino Nano which is connected to the host via USB and a daemon written in Python which publishes the states over MQTT.
|
|
|
+
|
|
|
+The Arduino reads the sensors/IO-Pins and sends state changes via Serial.
|
|
|
+The Python program runs as a daemon, receives the serial data and sends values/states to an MQTT broker.
