to rtl_433
Hi,
I have a Temp/Humidity sensor; its a Thingsend XZ-TH10. I am trying to decode this using rtl_433, but having enormous difficulty in getting anywhere. I am very new to RTL_433, so clueless as to where to go next.
The device is supposed to send temp/humidity data every 30s. So, I ran with the -A option and below is what I am getting. The device is intended to be run along with a "concentrator"; XZ TAG4. The chip inside this device is a XZ-DT25-UX v1.1 (http://thingsend.com/uploadfile/2018/0727/20180727054320128.pdf)
----------------------------------
rtl_433 version 20.11-9-g8cdb56d9 branch master at 202012151640 inputs file rtl_tcp RTL-SDR
Use -h for usage help and see https://triq.org/ for documentation.

Can someone please help me to decode this. Any help is appreciated.

Looks like you captured too different signals there. The FSK one seems disturbed and you might be too close to the center frequency. If you are looking for that signal try offsetting the frequency by 100kHz, e.g. if this is the default 433.92 then use -f 433.8M.
The other signal (OOK) is Manchester coded and well received. E.g. look at one of the pdv links and switch to MC. Looks like 28 bits, which fits a simple T/H sensor.
If you are not sure which signal is the right one: uplug the antenna and put the device at 10-30 cm from the receiver.
Then figure out the -X decoder and tabulate codes with the readout you expect. Then find a pattern ;)

Many thanks Christian.
The OOK signal was from a different device. I found this out by what you suggested; removed the antenna and placed the device close to it. I only get FSK signals now.

I tried with various frequencies, but none of them gave a decoded output. The manual (http://thingsend.com/index.php?m=content&c=index&a=show&catid=139&id=1) for the device lists 470.508MHz & 479.508MHz, tried those too.
Is there something I can do to scan to see what the right frequency is?

Getting an overview of the band is always a recommended first step. Use CubicSDR, Gqrx, or SDRangel. A poor-mans alternative is to record the band with `-w FILE.cu8 -T 120` for some frequencies and look at the files in https://triq.org/iqs/

ta.
I used CubicSDR, found pulses at 434.2MHz. Changed the frequency on rtl_433 to that, but it showed only single pulses.
I found this in the manuals for the sensor
The XZ-TP10 sensor data is encrypted and transmitted, and then the XZ-TAG series gateway analyzes and outputs
data protocol.
ID=xxxxxxxx,TEP=±xx.x·C,HUM=xxx.x%,S=0xxxxxxx,V=x.xxV,SN=xxx,RSSI=-xxxdBm
ID: Address data is number 0~9 of 8-bit ASCII;
TEP: Temperature data is ACSII’s -40.9~ +80.9. “℃”is ACSII’s “.”and “C”.
HUM: Humidity data is ACSII’s 000.0 ~ 100.0. The humidity data of XZ-TP10 is always 000.0;
V: The data of voltage is actual value, unit is “V”；
SN: Serial number of the transmitted data. The serial number of the frequency hopping will be increased when there is data hopping.
RSSI: Received signal strength indicator. The signal will be weaker when the value is smaller.
Where is says encrypted, would I be able to decode it using rtl_433?
the frequency listed is 433Mhz.

If possible open an issue for this at rtl_433. Attach a sample.
Don't use the center frequency, tune aside. Consider the spread also if it's FSK (FSK is actually two frequencies, you want neither directly in "the middle").

I am quite sure this is a Lora (LoraWan) based sensor. A signal
recording will verify that.

thanks for the help. created issue #1585. Have attached the signal recordings with rtl_433 -S all
Please let me know if any more info is needed or if I need to run more tests.
