It has been a while since my last post. But I have been working on something I waited for so long. I have a real smart-meter (instead of my previous Iskra ME162 digital meter that has no I/O ports that are active (infrared) or any other useable way to read out the meter without breaking the seal)

As promised some time ago here is the post explaining how I use my Raspberry PI to monitor my SolarPanel Output. I use PHP for this mather.
When I bought my solar panels back in november 2012, I knew that i wanted a Raspberry to communicate with the Solar inverter and read out the values to store them in a database. My preferred language to use was PHP. I will show you how I did this.
First a summary of the equipment I used :

Welcome back to part 3 already with DVB-T Fun with a Raspberry PI. In this part I will show you how you can profit from receiving all the data of your neighbors fancy wireless weather station data and use it for your own benefits.
Weatherstations with wireless sensors are very common and cheap now-a-days. Prices vary from 80 euro to a few hundred euros. What most of them have in common is the use of the LPD433 (Low Power Device 433 MHz) or unlicensed ISM band/SRD bandfrequency to transmit the data on air. (Among with wireless doorbells, cheap wireless alarms, car key-locks e.t.c…)
The maximum transmission power for these devices is 10mW max. This will cause you will be receiving only weather stations that are in your direct vicinity (depending on your antenna set-up of course)

Hello and welcome back! Part 2 of the series “Fun with Raspberry and DVB-T”
In this series we are going to use our previous setup to receive aircraft information with dump1090 . What aircraft is flying where? What altitude? Where is it heading to? All this information from the airplanes near the reach of your antenna can be grabbed from the air (1090Mhz) .. and all this with your little Raspberry and a cheap DVB-T Dongle.

In this chapter : Playing Radio with a Raspberry PI and a DVB-T Dongle.
You have probably heard about the cheap little USB Dongles made to receive digital Television and / or radio. They come in many shapes and forms (and prices) but you can find some cheap ones around the net. You can score one for around 10 € easy on ebay.
