Starting to use a RaspberryPI 3B with SBFspot and OpenHAB, to make a great automated house…
Things connected:

• MQTT-binding
• Arduino Mega with water-measurement acting as webserver & uploading to pvoutput
• WeMos D1 with DHT & LDR-sensor sending messages by MQTT, and getting water-items from Arduino-web-server also sending by MQTT to OH2
• WeMo wall switch with on/of button on BasicUI

In development

• Plugwise Circle’s connected to OH2

On wishlist / todo-list

• sending on/of messages to WeMo based on sunset & LDR-messurement “lights on when it’s getting dark”
