Zenner water meter payload
Hello everyone
Maybe one of you can help me.
I would like to read Zenner Lora water meters into a private Lora network with a UG65.
Item no.: ETK-MM-DN1580-LORASo far so good. But now I get very strange values.
Decoder:
/**
* Payload Decoder for The Things Industries and similar network servers
*
* @product EDC Communication Module
* @params
* – fPort: 1
* – bytes: Array of bytes
*/
function Decode(fPort, bytes) {
var decoded = {
removal_detection: 0,
battery_low: 0,
battery_end_of_life: 0,
hw_error: 0,
coil_manipulation: 0,
meter_values: []
};if (fPort === 1) {
// Status bytes decoding
var statusByte = bytes[0];
decoded.removal_detection = (statusByte & 0x01) ? 1 : 0;
decoded.battery_low = (statusByte & 0x02) ? 1 : 0;
decoded.battery_end_of_life = (statusByte & 0x04) ? 1 : 0;
decoded.hw_error = (statusByte & 0x08) ? 1 : 0;
decoded.coil_manipulation = (statusByte & 0x10) ? 1 : 0;// Meter values decoding
for (var i = 1; i< bytes.length; i += 4) {
// Assuming meter values are 32-bit unsigned integers
var meterValue = (bytes[i] << 24) | (bytes[i+1] << 16) | (bytes[i+2] << 8) | bytes[i+3] ;
decoded.meter_values.push(meterValue);
}
}return decoded;
}————–
Now I get the following in response:Power
Payload(b64)
kiUgAgICAAEQAAWq5i4CAAA=Payload(hex)
9225200202020001100005aae62e020000<div>and:
</div>{ "battery_end_of_life": 0, "battery_low": 1, "coil_manipulation": 1, "hw_error": 0, "meter_values": [ 622854658, 33554704, 371430, 771883008 ], "removal_detection": 0 }Can someone tell me where the measured value is hidden? Or how do I have to convert what?
<div> 😅< /div>
Many thanks and greetings to you

Here is a clearer overview of the payload
Hello @Laxr7,
As you have unfortunately not yet received any feedback on this enquiry here in the forum, we would like to do so. As it turns out, you have already received the documents you need from your colleagues at ZENNER Support 🙂 We hope this helped you and that you were able to integrate the meters into the other network?
Best regards!
@Community
Thank you very much, 🙏 yes, I received the documents and am already working on it.
Wish you a nice weekend already
Kind regards 🙏😄
Very good, then we wish you continued success with the information you received and a nice weekend too! 🙂
Best regards
Hi do you had any luck with creation of payload decoder?
Im looking for it also.
Can you help me?
Thank you
Hi,
yes it worked. why don’t you write me a PM
peace🙏
function decodeUplink(input) {
var bytes = input.bytes;
var status = bytes[0]; // Assuming the first byte contains the status summary bits
var data = {
removal_detection: (status & 0x01) >> 0,
battery_low: (status & 0x02) >> 1,
battery_end_of_life: (status & 0x04) >> 2,
hw_error: (status & 0x08) >> 3,
currently_unused: (status & 0x10) >> 4,
coil_manipulation: (status & 0x20) >> 5,
transceiver_monitoring_flag1: (status & 0x40) >> 6,
transceiver_monitoring_flag2: (status & 0x80) >> 7,
// … other status bits
};
// Assuming the next bytes contain meter values in SP12 format
var meterValues = [];
for (var i = 1; i < bytes.length; i += 4) {
// Day value (4 bytes) assuming little-endian
var meterValue = bytes[1] + (bytes[2] << 8) + (bytes[3] << 16) + (bytes[4] << 24);
meterValues.push(meterValue);
}
data.meter_values = meterValues;
return {
data: data,
};
