@nagelc said in New Setup for Home Environment Monitoring – Using NRF24L01+, Arduino Pro Mini, and BME280:
bme280
I read somewhere that the temperature sensor on the BME280 is sort of an afterthought. I did a few experiments comparing them to the DHT11/12/22 and found them only a little better. (Take this with a grain of salt, maybe you'll want to do you're own experiments.) I did do a lot of experiments with the DHT's and they really suck. +/-2°C Which turns out to mean +/-2°C offset (component variation) and +/-2°C measurement: +/-4°C from what the temperature actually is. My experience, yours may be better.
Please post your experience with OTA. I haven't tried it on Arduino's but it's awesome on ESP8266. I hesitate with Arduino's because I had some erratic behaviour running Arduino's when pushing the memory limit.
I, too, use the MQTT data transport to Home Assistant (HA) and I find that excellent. Getting data from HA is a bit tricky, but do-able. I have a flow meter and use HA to store the last read; meaning, if there is a power failure, HA sends the last read on Arduino boot. I don't use the EEPROM because that has a spec of 100,000 writes which the meter would do in about a year, thus, necessitating a new Arduino.
I truly appreciate you sharing. Thanks!

I faced similar issue and @TMRh20Projects replied in arduino forum. My issue was beacuse of cheap NRF modules chinese clones. After I replaced with good genuine ones, everything worked like a charm. Please check the NRF modules you are using. I wasted three days to figure out if there was some code issue, when at the end it was the NRF which created all the mess
Just to let you know that I solved the issue.
I found a library where you can control the speed and make sure it get to it's position.
You can find it here: https://github.com/netlabtoolkit/VarSpeedServo
I incorporated it in the Mysensor sketch and it works eventhoug it looks like it only goes like 90 degrees but it's enough for me :
#include <MySensor.h>
#include <SPI.h>
#include <VarSpeedServo.h>
// #include <Servo.h>
#define SERVO_DIGITAL_OUT_PIN 3
#define SERVO_MIN 0 // Fine tune your servos min. 0-180
#define SERVO_MAX 180 // Fine tune your servos max. 0-180
#define DETACH_DELAY 900 // Tune this to let your movement finish before detaching the servo
#define CHILD_ID 10 // Id of the sensor child
MySensor gw;
MyMessage msg(CHILD_ID, V_DIMMER);
VarSpeedServo myservo; // create servo object to control a servo
// a maximum of eight servo objects can be created
// Servo myservo; // create servo object to control a servo
// a maximum of eight servo objects can be created Sensor gw(9,10);
unsigned long timeOfLastChange = 0;
bool attachedServo = false;
void setup()
{
// Attach method for incoming messages
gw.begin(incomingMessage);
// Send the sketch version information to the gateway and Controller
gw.sendSketchInfo("Servo", "1.0");
// Register all sensors to gw (they will be created as child devices)
gw.present(CHILD_ID, S_COVER);
// Request last servo state at startup
gw.request(CHILD_ID, V_DIMMER);
}
void loop()
{
gw.process();
if (attachedServo && millis() - timeOfLastChange > DETACH_DELAY) {
myservo.detach();
attachedServo = false;
}
}
void incomingMessage(const MyMessage &message) {
myservo.attach(SERVO_DIGITAL_OUT_PIN);
attachedServo = true;
if (message.type==V_DIMMER) { // This could be M_ACK_VARIABLE or M_SET_VARIABLE
int val = message.getInt();
myservo.write(SERVO_MAX + (SERVO_MIN-SERVO_MAX)/100 * val,255,true); // sets the servo position 0-180
// Write some debug info
Serial.print("Servo changed. new state: ");
Serial.println(val);
} else if (message.type==V_UP) {
Serial.println("Servo UP command");
myservo.write(SERVO_MIN,255,true);
gw.send(msg.set(100));
} else if (message.type==V_DOWN) {
Serial.println("Servo DOWN command");
myservo.write(SERVO_MAX,255,true);
gw.send(msg.set(0));
} else if (message.type==V_STOP) {
Serial.println("Servo STOP command");
myservo.detach();
attachedServo = false;
}
timeOfLastChange = millis();
}
