Did you bought a 433mhz board or a 868mhz one?
I already checked the issue.
Your firmware has 868E6 lora band, and i need 433E6, can you compile .bin and share with me?
Hmm, are you sure 433mhz Lora is authorized on your country ?
433 is for Asia, Europe is 868 but was my mistake.
I think I solved the problem… I changed the value in config_LORA.h to 433e6 and now works properly.
If you add the bin the github here you go:https://github.com/htcheroportugal/lora433/blob/master/lora%20433mhz.bin
now missing connect reed switch and code, maybe some member for this community can help.
I flashed this code in Emitter Board:

}
I think the code for ReedSwitch is something like that:
const int reedPin = 2;
bool switchState = HIGH;
void setup()
{
Serial.begin(9600);
pinMode(reedPin, INPUT);
pinMode(ledPin, OUTPUT);
digitalWrite(ledPin, LOW);
}
void loop()
{
switchState = digitalRead(reedPin);
if (switchState == LOW)
{
Serial.println("ON");
}
else
{
Serial.println("OFF");
}
But i dont know how can do it.
I tried do to that but i think something is wrong.

LoRa.setPins(SS,RST,DI0);
if (!LoRa.begin(433E6)) {

while (1);
}
delay(1500);
}
void loop() {
{

if (switchState == LOW)
{

}
else
{

}
// send packet
LoRa.beginPacket();
LoRa.print(switchState);
LoRa.endPacket();
}
}
Because i receive repeated messages in loop.
Do you see a change in the mqtt payload when the button is pressed.
Glad you put your hands in the code !!
When my reed switch is closed i see
But always loop the messages does not stop… and the message should be “off” without Hello.
When my reed swich is Open i see “message” : “hello 1”} on loop to…
On arduino IDE serial monitor when opened
when closed
i am very close, but i need help to achieve my goal.
The issue is that you are sending the data even if there is no change between 2 loops. So before sending you need to check if the data changed or not.
So as to do that you need to store the data with a static prefix and compare the reed switch reading with the static data value.

Almost but the loop continues…

a Portuguese friend helped me with the part I didn’t understand and it’s working properly.
now i want keep a good work with other sensors
great that it’s working!
Feel free to share this code in the docs.

}I have been trying to understand how i can send more than one message, but i cant understand.
currently i´m trying to use BME280 sensor… and works more or less…
I got the message:
32.6324.6010099,36
I can understand that 32.63 is temperature 24,60 Humidity and 1009,36 Pressure…
How i can send 3 different values?

i use Home Assistant and only see ONE sensor too
When producing the LORA message, you should either follow a format to differentiate the values, either produce different messages.
I should work on an XtoLORA gateway that will work accordingly a LORAtoMQTT, this is on my plan but not at short term
I was checking the code and it does ot seems to difficult to to it. If you are interested I can publish a fork of OMG with XtoLORA functionnality, you may have to do some configuration and I would be interested by your test results.
yes please, do the fork, i will try because i tested a lot of sensors, tilt, bme280,dht,distance sensor, pir… etc and all works fine. This could be s great project if OMG supported more than 1 message Lora.
