Gas usage

Info  How  Charts

The smart meter that was installed in our house in September 2012, sends the gas consumption to my system. The most precise and convenient way of monitoring gas usage!

Remeha boiler

My Remeha boiler (Calenta model) is being monitored by using the Remeha Recom 'protocol' and a cable connected to the boiler. Whenever there are problems with the Calenta, I'll be the first to know cause problems will trigger an SMS to be sent to my cell phone. More information can be found here

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 :-)
