My FTDI-USB TTL is exposed at /dev/ttyUSB1, so this will be:
python intergas_prestige_cw6.py /dev/ttyUSB1
Output data is (hard-coded) stored at /home/pi/INTERGAS_DATA_%Y_%m.csv.
Reading of Intergas Prestige CW6 using the PC-interface.
Thanks to the folks of CircuitsOnline.net for doing all hard work decoding most of the protocol and connector layout.
I am the owner of of Intergas Prestige CW6 boiler and like to be able to read the data from the header for the SmartHouse Monitoring project.
The Intergas Prestige CW6 has an pc-interface found at X5. This is an ATX P4 connector which you can commonly source from old ATX power supplies.
I use a RaspberryPi with python coding to be a bit more versatile when it comes to storage, coding and forwarding.
Serial connection details: 9600 8-N-1 TTL found at X5:
I use a FTDI TTL @ Ebay.com set at logic level TTL of 5V using the jumper, connectors setup:
