I use the latest 1.0.6 IDE on Win7 and loaded the latest MySensor libraries
https://github.com/mysensors/Arduino/
Added the attached libraries and they compiled just fine for me...

MyMQTTGateway.zip
Note1: Included is MyMQTTGateway and Pubsubclient.

Note2: This will make the gateway act as a MQTT client so you need Mosquitto (or similar) where you publish the topics from the gateway.

Note3: Remember to change the IP and Mac.

Cool project! Following.

@kunall

First these two rows before setup..

int BATTERY_SENSE_PIN = A0;  // select the input pin for the battery sense point
int oldBatteryPcnt = 0;

and in the loop i have these rows...

// get the battery Voltage
int sensorValue = analogRead(BATTERY_SENSE_PIN);
//Serial.println(sensorValue);
// 1M, 470K divider across battery and using internal ADC ref of 1.1V
// Sense point is bypassed with 0.1 uF cap to reduce noise at that point
// ((1e6+470e3)/470e3)*1.1 = Vmax = 3.44 Volts
// 3.44/1023 = Volts per bit = 0.003363075
float batteryV  = sensorValue * 0.003363075;
int batteryPcnt = sensorValue / 10;
Serial.print("Battery Voltage: ");
Serial.print(batteryV);
Serial.println(" V");
Serial.print("Battery percent: ");
Serial.print(batteryPcnt);
Serial.println(" %");
if (oldBatteryPcnt != batteryPcnt) {
 // Power up radio after sleep
 gw.sendBatteryLevel(batteryPcnt);
 oldBatteryPcnt = batteryPcnt;

in OpenHab items i have this row...

Number node2_batt  "Battery [%.1f %%]" <energy> (node2,All)  {mqtt="<[MySensor:MyMQTT/21/1/V_VAR1:state:default]"}

hope this helps....

Oh! Where do I order?! Been waiting for this!

I've seen these and also got interested. Any input on these is appreciated.

Great work!

Great, thanx! I have to look into this, so tired of the experimentboards

Well, I see some of you creating great custom boards in many (very interesting) sizes and shapes.
But for a n00b in that area... if i would get hold of a gerber/eagle file, how and where do you go about to order them? Is there any "how-to"?

@TommySharp
Hmm dont really remember, but I think this was the solution
https://github.com/knolleary/pubsubclient/issues/46

When you order, lägg till 5st

Where can one find these boards?
