I updated some temp/hum(DHT22) sensors with nodemanager a month ago. And at the same time I removed the LED and the regulator on the Arduino pro mini. But now I have problems with my sensors. It send some strange values to Domoticz, see attached picture. I have the problem on all sensors but the time between the low value is different and it is also not at the same time on two sensors. Can anyone please give me a hint on what to do?

#include "config.h"
#include <MySensors.h>
#include "NodeManager.h"

NodeManager nodeManager;

void before() {
  Serial.begin(MY_BAUD_RATE);
  nodeManager.setSleep(SLEEP,1,MINUTES);
  nodeManager.setBatteryMin(1.8);
  nodeManager.setBatteryMax(2.4);
  nodeManager.setBatteryInternalVcc(true);
  nodeManager.setBatteryPin(A0);

  nodeManager.registerSensor(SENSOR_DHT22, 3);
  nodeManager.before();
}

void presentation() {
  nodeManager.presentation();
}

void setup() {
  nodeManager.setup();
}

void loop() {
  nodeManager.loop();
}

void receive(const MyMessage &message) {
  nodeManager.receive(message);
}

void receiveTime(unsigned long ts) {
  nodeManager.receiveTime(ts);
}
