Thanks man!

yes like that.

Is it possible to always show multiple temperature sensors in one graph?
I have several temperature sensors and wants to make clear map

U have the wrong speed selected it must be 9600 Baud

// Via the serial port of the Pi you can set the initial counter values.
// do this while the Arduino is connected to the Pi but Domoticz is not running.
// Set the serial port to 9600 Baud.
// If not set, the counter will not start updating.
