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

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

[sindalschmidt]

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!

[SteveCooling]

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.

[sindalschmidt]

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.

[zuckschwerdt]

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.

[ProfBoc75]

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.

								x							x	x
Byte		00	01	02	03	04	05	06	07	08	09	10	11	12	13	14

Data Layout : bitbench here

PP: preamble{48} 6 bytes : 0xAA AA AA D3 15 27
UU: Unknown{8} 1 byte : lower nibble changed between Open & Close
II : Unknown{48} 6 bytes : Fixed value 0xDC 3C E3 12 65 33 ( ID ?)
SS : {8} 1 byte : State Open 0x25 / Close , 0x24 , so lower nibble changed between states.
CC: {8} 1 byte : CRC-8 from byte 6 to 13 (so without preamble) , 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.

[sindalschmidt]

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.

[sindalschmidt]

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?

[ProfBoc75]

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

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.

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.
