Zenner Wasserzähler Payload
Hallo Zusammen
Eventuell kann mir jemand von euch weiterhelfen.
Ich möchte gerne Zenner Lora Wasserzähler in ein pivat Lora Network mit einem UG65 einlesen.
Artikel-Nr.: ETK-MM-DN1580-LORASoweit so gut. Nun erhalte ich aber sehr komische Werte.
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;
}————–
Nun erhalte ich folgendes als Antwort:Power
Payload(b64)
kiUgAgICAAEQAAWq5i4CAAA=Payload(hex)
9225200202020001100005aae62e020000<div>und:
</div>{ "battery_end_of_life": 0, "battery_low": 1, "coil_manipulation": 1, "hw_error": 0, "meter_values": [ 622854658, 33554704, 371430, 771883008 ], "removal_detection": 0 }Kann mir jemand sagen wo sich der Messwert versteckt? Oder wie ich was umrechnen muss?
<div>😅 </div>
Vielen Dank und Grüsse an euch

Hier noch der Payload etwas übersichtlicher
Hallo @Laxr7 ,
da du hier im Forum leider noch keine Rückmeldung bekommen hast zu dieser Anfrage, wollten wir dies einmal noch gerne tun. Wie sich ergeben hat, hast du ja die benötigten Dokumente inzwischen bereits von den Kollegen des ZENNER Supports erhalten🙂. Wir hoffen, dass dir damit geholfen wurde und du die Zähler in das andere Netzwerk einbinden konntest?
Herzliche Grüße!
Besten Dank, 🙏 ja habe die Dokumente erhalten und bin bereits dran.
Wünsche bereits ein schönes Wochenende
Freundliche Grüsse 🙏😄
Sehr gut, dann wünschen wir dir weiterhin gutes Gelingen mit den erhaltenen Informationen und ebenfalls ein schönes Wochenende! 🙂
Herzliche Grüße
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,
};
}
Hello Laxr7 & community,
I am trying to the same thing as you did.
I am using a Mikrotik LR8 and a Zenner IUWS v1.8.5
The IUWS is sitting on the table, so it shows dry_pipe, and zero water volume.I have the join and accept part in place, I have the decrypt key and I receive the up-payload.
I can’t decode pipe_dry correctly with the decoder shown, or other decoders for that matter…
I guess there are other differencies on the IUWS model, so are there more documentation than the Radio_communication-scenario-list-IUW_IUWS.pdf show.
It is not giving the full dataframe schema…
Or even better, is there a decoder for the IUWS cold water meter?Kind regards,
Balle-LarsenHello @Balle-Larsen , perhaps @Laxr7 still has some helpful information for you based on his experience (if you haven’t already been in contact with him directly). Otherwise, we can also recommend that you contact ZENNER Support at support@zenner.com. They will certainly be able to help you further, possibly with additional relevant documents.
Warm regards!
Hello,
I’m alos trying to integrate water meter Zenner, model IUWS DN15 R500 FK into my gateway and i want to ask where do you get the documentation for the payload codec or a codec from? (i think all zenner water meter IUWS use the same codec)
Can anyone help me with this?
Thank you.
Hi @greedy , the best way as mentioned before should be to directly contact the ZENNER Support at support@zenner.com. They can give you all available documents for that.
Warm regards 🙋♂️
