@Pierre-P you controller image looks great . What controller is it ?

[Pierre P]

@iotcrazy It is Jeedom, you can find some information here: http://www.mysensors.org/controller/jeedom
It use an RPI2 if you ant to make it yourself, and a major version will come during the week !

@martinhjelmare Any idea why siVolt is reporting values rounding up to either 2V or 3V in Domoticz? All I'd like to have is something like 2.9V

@alexsh1

How are you calculating and sending it? Did you change to float? There was a bug in my original sketch.

Make sure at least one of the operands is a float in the division.

float siVolt = vcc / 1000.0;

@martinhjelmare

Yes, it is declared as float

void sendBattLevel(bool force)
{
  if (force) lastBattery = -1;
  long vcc = readVcc();
  if (vcc != lastBattery) {
    lastBattery = vcc;
  float siVolt = vcc / 1000;
#ifdef BATT_SENSOR
    gw.send(msgBatt.set(siVolt, 2));
#endif

It is reported as either 2.000V (battery) or 3.000V (USB) in Domoticz
Changing siVolt to int or changing 2 in set does not change anything.

@alexsh1 said:

float siVolt = vcc / 1000;

You should change 1000 to 1000.0, i.e. a float. Float math will be used if any of the operands is a float.

@martinhjelmare Stupid me! Thanks for bringing this up - these issues are so simple, but very easy to overlook. I was about to start pulling my hair out....
