Add Door/Window sensor to Cavius

Add Door/Window sensor to Cavius decoder

I have submitted a pull request to add sample test files that I have captured. I have also added them here: Cavius-door-sensor-captures.zip

Currently the Cavius decoder only supports Smoke, Heat and Water alarms. The Cavius lineup also has door/window sensors. I have attempted to modify the cavius.c decoder myself without luck and are now looking for help.

In the files attached I have made 2 captures; one when opening the door and one when closing the door. If someone can point me in the right direction, I will be able to modify the cavius.c and test right away locally. Any help is much appreciated, as I have no experience with radio signals.

@SteveCooling are you able to assist here? I really appreciate your initial commit of supporting Cavius smoke/heat/water alarms. I rely on it. Thank you!

Hi @sindalschmidt

Your 2 captures can't be decoded, the signal is too strong. Can you try again, please. reduce the gain and/or not too close to the sensor, at 1 meter not less, and/or remove the antenna from the rtl dongle.

But for what I can see using Pulseview, it's not a cavius coding. too small message compare to existing capture into rtl_433 test.

Modulation is still FSK_PCM but pulse is around 415 µs instead of 206 µs.

Both Open and Close are distinct signals with different values.

try this :

rtl_433 -F 868.68M -X "n=cavius,m=FSK_PCM,s=415,l=415,r=1500"

You should have around 120 bits message. Here in hexa your 2 files (manually transcript from Pulse view). More or less this :

Close	AA	AA	AA	D3	15	27	FE	DC	3C	E3	12	65	33	24	EC
Open	AA	AA	AA	D3	15	27	FF	DC	3C	E3	12	65	33	25	F8

@SteveCooling are you able to assist here? I really appreciate your initial commit of supporting Cavius smoke/heat/water alarms. I rely on it. Thank you!

Sorry, there's nothing I can do at this point. Glad my contribution is working for you, though.

Can you try again, please.

Thank you for assisting me! I have made two new captures with the antenna removed. Cavius-door-sensor-captures2.zip

According to the cavius.c file, the Cavius radio signals are Manchester encoded.

try this :

rtl_433 -F 868.68M -X "n=cavius,m=FSK_PCM,s=415,l=415,r=1500"

I do get some output, but it doesn't seem to line up with me opening and closing the door.

Thanks again for helping!

Just a quick note, It might well be that the door sensors are using a completely different packet format. I don't think Cavius would want the door sensors waking up their sleeping (battery powered) smoke sensors every time you walk through a door.

Good point, that makes sense. I hope my captures can help point us in the right direction then. I'm definitely getting larger samples when collecting upon opening and closing the door. In between there are small captures, so I can definitely tell them apart. They also line up quite well right after opening/closing the door.

FSK 400 µs looks about right. But the reset needs to be longer: rtl_433 -f 868.68M -X "n=cavius,m=FSK_PCM,s=415,l=415,r=2500" You should see codes of 100 or more bits length so {100}or more with 14 or so chars code.

Hi ,

Here, my findings: Only 3 bytes changed between open & close, and always same bytes.

Byte 6 doesn't have the same value between close & open state
Byte 13 is 0x25 when Open and 0x24 when Closed.
Byte 14 is the CRC 8 value from 6 to 13 bytes , poly 0x07, init 0x00.

I looked to the Cavius guides, the sensor should provide also low battery signal from these byte, I can't say which one, you must test with dc supply. So remaining some work to get the figures.

You should see codes of 100 or more bits length so {100}or more with 14 or so chars code.

Thank you for the suggestion! Unfortunately it's not as expected, but I do see changes when opening and closing the door. At 22:10:42 I open the door. At 22:10:54 I close the door. But the length is not as expected. I have tried adjusting the reset a bit without luck.

Let me know if I should do more captures, if that's helpful. Thank you for taking your time with me.

Only 3 bytes changed between open & close, and always same bytes.

Very interesting findings! Thank you so much for your contribution. How can I implement this to capture these events; either by modifying the cavius decoder, build a new one or use a flex decoder?

Hi @sindalschmidt

About the captures, your cu8 files are still not good enough to be decoded by rtl_433. I was able to decode them only manually and from Pulseview graphics of the signal.

Try to capture with sample rate at 1000k, this should be the default at 869Mhz so do not put -s 250k option, shift the frequency to 869MHz to avoid the DC offset / to correct the IQ:

rtl_433 -f 869M -X "n=cavius,m=FSK_PCM,s=415,l=415,r=2500" -S unknown

You can play with the gain : 0 = auto , then 1 to 50 , it will depend on the RTL dongle, from +1 to +49db of gain.

rtl_433 -g 0 -f 869M -X "n=cavius,m=FSK_PCM,s=415,l=415,r=2500"
rtl_433 -g 20 -f 869M -X "n=cavius,m=FSK_PCM,s=415,l=415,r=2500"

You can play with the FSK pulse detector mode -Y :

rtl_433 -g 0 -f 869M -X "n=cavius,m=FSK_PCM,s=415,l=415,r=2500" -Y autolevel
rtl_433 -g 0 -f 869M -X "n=cavius,m=FSK_PCM,s=415,l=415,r=2500" -Y classic

About the device decoder: (let me know if you need help on the coding part)

you can use the current cavius.c, add the new demodulation settings and add a new decoding part, lot of devices are working this way.
or you can create a new device decoder. It will create a new device number.
flex decoder is good to start, to test, but it could be nice to get the CRC 8 decoding/control and then avoid false positive.
if flex decoder is ok for you, you can create a .conf file and get the sensor be decoded as others, but CRC will not be checked, something like this:

rtl_433 -g 0 -f 869M -X "n=cavius,m=FSK_PCM,s=415,l=415,r=2500,preamble=d31527,bits>=100,get=@104:{8}:state:[0x25:Open 0x24:Close" -Y autolevel

Try to capture with sample rate at 1000k, this should be the default at 869Mhz so do not put -s 250k option, shift the frequency to 869MHz to avoid the DC offset / to correct the IQ:

I have received confirmation from the manufacturer, that the device sends using 868.65Mhz with FSK. I therefore kept it at 868.65Mhz. Let me know if I should still use 869Mhz to get better captures for you.

The below are captures from when opening the door at around 11:42:53 which generates captures number 10 to 16. At around 11:43:08 I close the door, which seem to generate capture number 21 to 26. 868.65M_1000k.zip

rtl_433 -f 868.65M -p 9 -X "n=cavius,m=FSK_PCM,s=415,l=415,r=2500" -S unknown

Gain and pulse detector

Playing around with these unfortunately only continues to produce these meaningless (at least to me) messages already shown above. I can't seem to get messages large enough (>=100). I appreciate your suggestions and yes, I would very much like help with the expanding the cavius.c coding, once we have something to aim for here. Hopefully the new captures can give some insights.

Yes it's better to not be at the exact frequency, to remove the dc offset that could be introduce by rtl dongle or signal. If you use SDRSharp , you may see a spike at the tuned frequency in the middle of the screen and in the rain fall , this is the dc offset that will alter the signal.

With -f 869M, the sample rate at 1000khz will cover from 868.5 Mhz to 869.5 Mhz so including your signal at 868.65 Mhz.

I will check later your captures.

Hi @sindalschmidt

Back to your cu8 cap files:

g001, 2, 4, 5, 7, 18, 26 = Noise = trash can
g003, 6, 8, 9, 10, 17, 19, 28 = another sensor 1, not recognized by rtl_433 but could be, modulation is fsk_pcm, short=long=15, always same value {127/128}: aaaaaaaaaa84c37c76557412fe829d
g025, 27 = another sensor 2, not recognized by rtl_433, FSK_PCM, short=long=10 (Edit = Wireless MBus signal)
g011 -- > g016, g020, 22, 23, 24 = look like your previous captures for Cavius
g021 is dirty with a mix of 2 signals with Cavius + other sensor 1.

About the Cavius captures, it's still clipping (too loud) and can't be decoded. Try more distance, remove antenna, and lower gain (try step by step, start at lower gain with -g 1, then -g 2 ... up to -g 50, but 50 will be too strong too).

rtl_433 -g 1 -f 869M -X "n=cavius,m=FSK_PCM,s=415,l=415,r=2500,preamble=d31527,bits>=100,get=@104:{8}:state:[0x25:Open 0x24:Close" -S unknown
rtl_433 -g 2 -f 869M -X "n=cavius,m=FSK_PCM,s=415,l=415,r=2500,preamble=d31527,bits>=100,get=@104:{8}:state:[0x25:Open 0x24:Close" -S unknown
rtl_433 -g 3 -f 869M -X "n=cavius,m=FSK_PCM,s=415,l=415,r=2500,preamble=d31527,bits>=100,get=@104:{8}:state:[0x25:Open 0x24:Close" -S unknown

About the clipping: Using PulseView application to see it (need first to convert cu8 to sr file like this rtl_433 -r g011...cu8 -w g011...sr, you will see the 2 information I and Q, yours , they look like square signal and should be sinusoidal, this means that it's too strong, and clipping the signal.

Clipping / square (your Cavius cu8 files): then FSK or ASK is not decoded. Zoom in Zoom out

Good sinusoidal signal (expected): FSK is decoded here Zoom in Zoom out

Hi @ProfBoc75

I apologize for the delay in responses. I really appreciate your help and the detailed responses. I have taken new captures with the antenna removed and the base (of the antenna) hanging down from my metal cabinet, as well as capturing with rtl_433 with a gain of -20 (as well as -18, -10 and 0).

I have installed the software PulseView and from what I can see of these captures, the I and Q are not clipping with these captures: g112-g142.zip

rtl_433 -g -20 -f 869M -X "n=cavius,m=FSK_PCM,s=415,l=415,r=2500,preamble=d31527,bits>=100,get=@104:{8}:state:[0x25:Open 0x24:Close" -S unknown

From g121 to g127 I open the door. From g133 to g140 I close the door. I hope these works – otherwise let me know and I will keep trying my best to improve the captures.

Thank you.

Edit: Unfortunately it doesn't look like FSK is decoded in any of them.

Edit 2: It looks like there might actually be something in 138 and 139. I have also learned that this door sensor is not necessarily branded Cavius, but works on the same ecosystem as Cavius. Perhaps, as pointed out by @SteveCooling, they might be speaking a little differently. Nonetheless, if there is no FSK in the captures, we have nothing (right?).

Hi @sindalschmidt

It's better, but I guess the tuner FC0012 is guilty here and not good at this frequency. I was facing same kind of issues where this tuner is not working properly for a weather station at 868 MHz and it's working fine with a R820T/R828D tuner.

Can't help more on this rf side, may be increase again the sample rate? I can help on the coding part, but if rtl_433 is not able to understand the raw signal, it will be useless until we find the reason why.

@zuckschwerdt @merbanan , need your help here, please. I found the decoding data layout and crc , but the signal itself , we can't get the FSK decoding despite the tuning with the gain and sample rate. any idea ? next steps ? Thanks.

In g125 the gain is still too high and we get clipping. E.g. g135 seems a little better with not too much clipping. Best advice I have currently: reduce gain or increase distance and also maybe try to get a little closer to center so it's easier to inspect, perhaps -f 868.93M

Hi @ProfBoc75 and @zuckschwerdt

I have dismounted the sensor and moved around the house with it. I have made some captures and tried finding the most optimal ones. The two captures attached here are taken with the antenna removed and 4 walls between the base of the antenna (antenna removed) and the sensor. Looking with pulseview there are definitely something in FSK to look at. I hope it's not just noise that I've captured – it is much more difficult to distinguish the captures.

g224 I "close" the sensor and g246 I "open" the sensor. g224-g246.zip

I have made a lot more captures at different frequencies, but most notable some with sample rate at 250k, as noted in the Cavius decoder, which should be more reliable. In the attached file I have selected all captures with what seems solid FSK readings; especially g019_868.67M_250k.sr and g021_868.67M_250k.sr. more captures.zip

Note that recordings are .cu8, the .sr are converted for screen display only. (You could also use the .cu8 on https://triq.org/spectrogram-next/ directly for a similar display.)

Alright, thank you for pointing that out. Here are the actual recordings in .cu8

captures.zip

There are two different signals in the recordings: at 868.93 M, fast with wide deviation and at 868.64 M, slow with narrow deviation -- I suspect the latter the one we are looking for. (My suggestion of -f 868.93M was an error reading the freqs, you are right to use -f 868.70M)

It's interesting how different the signal looks in 1000k (a straight line of FSK) vs the 250k (somewhat freq instable).

And it looks like the -f 868.70M -s 250k recoding (g003_868.7M_250k.cu8) is somewhat readable by rtl_433.

Hi @zuckschwerdt : yes, the second signal is a Wireless MBus signal well decoded by rtl_433 if you add the -Y minmax.

For the rest, I don't know enough how the signal is decode by rtl_433 to get the FSK PCM , but something around the sampling rate and the frequency of the signal alter the result. may be the sensitivity of the tuner FC0012 and SNR ? May be use an extension USB cable to improve the signal quality. I don't know if @sindalschmidt can use another kind of rtl dongle like the RTL-SDR v3 or any RTL with R820T/R828D/R860 tuner ?

Sorry for the late reply. Yes, the wireless mbus has been around for a while. I suspect a neighbor somewhere. Unfortunately I do not have another dongle. Can you explain a little about how you were able to manually tell the "Open" and "Close" signals apart, but rtl_433 is not able to? I'm curious of this. The dongle has no issues decoding the Cavius smoke, heat and water sensors that I have.

And it looks like the -f 868.70M -s 250k recoding (g003_868.7M_250k.cu8) is somewhat readable by rtl_433.

Can we work from here and do some fine tuning?

Hi @sindalschmidt :

The signal is transmit in an analog way, here it's a FM signal for frequency modulation.

Then we need to transform this analog signal into a digital signal, the FSK decoding, FSK for frequency-shift keying. In fact, there are 2 frequencies, one for ~~blank~~ space (lower frequency) , the other one for the ~~pulse~~ mark (higher frequency). Then, depending on the digital coding, the ~~pulse~~ mark can be 1 and ~~blank~~ space 0.

So, I looked into your cu8 files, made by rtl_433, which contains lot of information.

The I & Q signals, they are the analog rf signal : I/Q signaling refers to the use of two sinusoids that have the same frequency and a relative phase shift of 90°
The AM signal / analog , from I & Q --> here the amplitude do not change, so it's simple line.
The FM signal / analog , from I & Q --> I looked here, you have the 0 and 1 you can guess
The Frame information / digital = start / stop of the signal transmit
The ASK (for Amplitude Shift Keying) information / digital = the AM signal converted into digital information based on Amplitude changes.
The FSK (for Frequency Shift Keying) information / digital = the FM signal converted into digital information based on Frequency changes.

Usually we just need to look at the FSK or ASK already decoded line (done by rtl_433), but here, you have nothing, so I looked into the FM line, where we can guess the figures. See my previous screenshots. You understand that since rtl_433 is not able to decode the FSK, it can not be able to show you any result.

Then, carefully, for each file, I wrote down the 0 and 1 into an excel table (can be done from bitbench web site), convert the binary information into hexa data and I analyzed the result.

Between the 2 states, you have very few bit / byte changes, and I found which bit / byte changed. About the data layout, it's a classic preamble AA AA then the sync-word 0xD31527, then the useful information like ID / State / CRC (CRC to validate the data integrity).

Where are we on this? Is there a path to a PR?

I've marked this inactive to make it easier to ignore.
