Min varmepumpe er en Viessmann Vitocal 222 luft-vand.

Jeg bruger vcontrold til at hente data fra det optiske interface.

git clone
sudo apt-get install cmake libxml2-dev python3-docutils
cd vcontrold
mkdir build
cd build
cmake ..
sudo make install
# Indstaller konfigurationsfil:
sudo mkdir /etc/vcontrold
sudo chown pi /etc/vcontrold
cp ../xml/300/vcontrold.xml ../xml/300/vito.xml /etc/vcontrold/

 Ret /etc/vcontrold/vcontrold.xml til, specielt tty og device ID

<?xml version="1.0"?>
<V-Control xmlns:vcontrol="">
      <!-- These are the default settings vcontrold drops privileges 
           to when started as root. Be sure to have the respective 
           user and group. If you use a serial device, be sure to 
           have read and write permissions on the corresponding
