Battery level don't show up

[cheesepower]

Hello all,

I encounter an issue with my battery powered sensor.
It's based on an arduino pro mini 3,3 V, a DHT 22 and powered via a LiPo 3,7V battery.

It runs on a Vera 3 with the 1.4 library.

After inclusion, my vera see 1 node, 1 humidity sensor and 1 temperature sensor. The temperature and humidity are working fine, The problem is that the battery level don't show up :-(
On th serial connection i can see my battery level.

Here is my code:

''''
#include <SPI.h>
#include <MySensor.h>
#include <DHT.h>

#define CHILD_ID_HUM 0
#define CHILD_ID_TEMP 1
#define HUMIDITY_SENSOR_DIGITAL_PIN 3
unsigned long SLEEP_TIME = 300000; // Sleep time between reads (in milliseconds)
int BATTERY_SENSE_PIN = A0; // select the input pin for the battery sense point

MySensor gw;
DHT dht;
float lastTemp;
float lastHum;
boolean metric = true;
MyMessage msgHum(CHILD_ID_HUM, V_HUM);
MyMessage msgTemp(CHILD_ID_TEMP, V_TEMP);
int oldBatteryPcnt = 0;

void setup()
{
gw.begin();
dht.setup(HUMIDITY_SENSOR_DIGITAL_PIN);

// Send the Sketch Version Information to the Gateway
gw.sendSketchInfo("Humidity", "1.0");
gw.sendSketchInfo("Battery Meter", "1.0");

// Register all sensors to gw (they will be created as child devices)
gw.present(CHILD_ID_HUM, S_HUM);
gw.present(CHILD_ID_TEMP, S_TEMP);

//metric = gw.getConfig().isMetric;
}

void loop()
{
delay(dht.getMinimumSamplingPeriod());

float temperature = dht.getTemperature();
if (isnan(temperature)) {
Serial.println("Failed reading temperature from DHT");
} else if (temperature != lastTemp) {
lastTemp = temperature;
if (!metric) {
temperature = dht.toFahrenheit(temperature);
}
gw.send(msgTemp.set(temperature, 1));
Serial.print("T: ");
Serial.println(temperature);
}

float humidity = dht.getHumidity();
if (isnan(humidity)) {
Serial.println("Failed reading humidity from DHT");
} else if (humidity != lastHum) {
lastHum = humidity;
gw.send(msgHum.set(humidity, 1));
Serial.print("H: ");
Serial.println(humidity);
}

// 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 * 0.0041;
int batteryPcnt = sensorValue / 10;

Serial.print("Input Value: ");
Serial.println(sensorValue);

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;
}

gw.sleep(SLEEP_TIME); //sleep a bit
}

@cheesepower I've notice that sometimes it take a while for the indicator to show up in Vera.

My sensor runs for 2 weeks now.

One more question : where did the battery level is supposed to be ? on the node under a variable or elsewhere ?

Looks like this.....

I have this:

I assume you've done extensive resets, reloads, reboots of sensor, vera, luup, and gateway in all diffent ways?
And a little dare to use custom device names before you get it going if you ask me.
And yes, the battery level as a number is also visible under variables after first receive..

@cheesepower as @m26872 suggested, you should try a power cycle your equipment.. if that doesn't work...... you have a problem. I can't see any issue in the sketch.

[cheesepower]

Yes i made several reset, exclusions, inclusions, vera reset and clear EPROM but nothing worked...

I made a new sensor and it works perfectly

Strange... I will try again when i will have more time.

Thanks for the help :D
