I now have a working solution where the P1 port of the Smartmeter is connected to an Arduino with Ethernet shield. Some of the values are send to an Syslog server in my local network.

Now i need a way to visualise the data.

Problem is solved. I had two problems. Reading 7E1 instead of 8N1 and a timing problem. The first is solved by a comparison of the byte received. By subsracting 128 if the byte is larget than 128 , you get the same result as 7E1. The second problem was solved by altering the timing of the arduino by...

Almost there. /XMX5XMXABCD100012575 0-0:96.1.1(4B383257303039373836393837313131) 1-0:1.8.1(000053.971*kWh) -1.0052k)1:.1000*W -2.0000k) 064(0)1:7(008W 02.000*)0:.09* -9311 0611 -91.)0:.0383131130311)0:..0 -23(2220(C6((122)3 009)0:4.2 Looks like some dataflow problem.

Verry much interrested. I'm currently have a smart meter (electricity and gas) installed and it has a P1 port. Currently i'm trying to connect it to an Arduino board. I can see data comming out the port, however it's not readable yet due to my lack of knowledge about serial communication with the Ar...

We hooked the meter to a arduino board with ethernet shield. I programmed the device to parse the information from out meter and send it via HTTP request to a server. @ pjanssen, They just installed my new electricity and gas meter. It has a P1-connector. I tried to hook it to an Arduino, and got d...
