Node battery voltage in openHAB iOS

[ben999]

Hi all
I have a question regarding this topic :
battery powered arduino without resistors
I have just implemented this in a motion/temp/humidity sensor
-> Arduino Pro Mini with NRF24, DHT22 and SR501 (converted to 3.3V as per "Build" instruction)
I inserted this bit of code into mysensor code :

#include <Vcc.h>
const float VccExpected   = 3.0;
const float VccCorrection = 2.860/2.92; 
Vcc vcc(VccCorrection);

void loop()
{
    int batteryPcnt = (int)vcc.Read_Perc(VccExpected);
   sendBatteryLevel(batteryPcnt);
}

I am pretty happy with the result, as i can now see voltage within PaperUI :)

Now how would i get that in "things", "items" and "sitemap" ? So i can get my node battery voltage in openHAB iOS...
Do I need to create a new child that "carries" this info?

Thanks a lot for your help

@ben999 : Here's an example how to integrate the battery percent value: https://github.com/tobof/openhab2-addons/wiki/Examples
Look for bathBat01.

@TimO saving my evening once more !

I got so much inspiration from that link already... and tonight's solution was there all along!!!

It is now working fine, with icon changing according to voltage changes !!!

Thanks a lot Tim!!
