@Inso - you can eventually register a few TEXT devices with one of your Arduino sensors, like:
present(LCD_LINE1_CHILD_ID, S_INFO, LCD_LINE1);
then periodically ask data back from Domoticz like:
if (!line1received) {
request(LCD_LINE1_CHILD_ID, V_TEXT);
#if DEBUG == 1
Serial.println("Requested line1 from gw !");
#endif
wait(5000, 2, V_TEXT); // wait for 5s or until a message of type V_TEXT is received
}
just define this first:
bool line1received = false;
For more details on the DzVents (2.4x) side have a look in the Domoticz installation folder, there are a few good DzVents examples, this is the path in Windows7:
C:\Program Files (x86)\Domoticz\scripts\dzVents\examples
Hope it helps ...
