Roller shutters

A total of 12 Roller shutters suited with Somfy RTS motors are controlled by my system. Part of those shutters are being controlled automatically based on light sensors, inside temperatures to improve the usability of these roller shutters.

Current Power usage

How  Charts

A very nice feature of our smart meter is that it also sends detailed information about the current power usage to my system - every 10 seconds.

Pressure Sensor (ZigBee)


Since February 2010 a wireless pressure sensor is used to measure the pressure. This sensor is a DIY project where i combined an Arduino-like JeeNode  and XBee modules  to create my first self made, battery powered sensor.

User Interfaces


Just like the rest of the software of my Domotica system, i also created my own User Interfaces: a Touchscreen, a Philips Pronto TSU9600 and a Apple iPod Touch can all be used to control our house. And with this website of course :-)
