Add decoders for AC114-xxB and BeSmart_Sx #2242

Closed TheChatty closed 1 year ago

TheChatty commented 1 year ago

SignalDuino already has support for AC114-xxB and BeSmart_Sx.

Using rtl_433_ESP both devices are reported as "unknown protocol".

Top two links from first post describe the SignalDuino RF protocol. I am able to send the follwing commands:

AC114-xxB:

canvas up   --> set sduino sendMsg u56#0xA347969601000B7F8#R3
canvas stop --> set sduino sendMsg u56#0xA3479696010023978#R3
canvas down --> set sduino sendMsg u56#0xA3479696010043B78#R3

BeSmart_Sx:

fan light  --> set sduino sendMsg P78#0x53490#R4
fan 5min   --> set sduino sendMsg P78#0x53481#R4
fan higher --> set sduino sendMsg P78#0x53488#R4
fan lower  --> set sduino sendMsg P78#0x53484#R4

@zuckschwerdt What can I help you with? Do you need multiple samples from the same key presses or samples from each key? Is the code from SignalDuino any help to you?

zuckschwerdt commented 1 year ago

You can try a flex decoder to make sure we got things right: rtl_433 -R 0 -X 'n=name,m=OOK_PWM,s=200,l=500,r=800,bits>=20' This should output codes for both senders.

If that works out we need to identify more fields, there should at least be an ID field. Can you change a "house code" on these? Or do IDs reset on battery change? What changes in the output if you do?

zuckschwerdt commented 1 year ago

Oh, and a sample of each would be great. Just upload here as zip. https://triq.org/rtl_433/ANALYZE.html

TheChatty commented 1 year ago

@zuckschwerdt: The general purpose decoder outputs codes for both senders and each button.

Samples.zip

Each button was pressed 4 times (and saved to independent files). I used your -X settings. I have no info about the bits and I don't know how reset and pair them to cause new key bits.

TheChatty commented 1 year ago

@zuckschwerdt Can I help more?

zuckschwerdt commented 1 year ago

There is just the long sync to handle, use it like this:

rtl_433 -R 0 -X 'n=name,m=OOK_PWM,s=200,l=500,y=5250,r=800,bits>=20'

And you can read all codes.

You get:

That's all there is. Write a .conf file (see https://github.com/merbanan/rtl_433/tree/master/conf) or use just on the command line. Use ,match= to select actions, and use ,countonly for a shorter output. E.g.

rtl_433 -R 0 -X 'n=AC114-down-press,m=OOK_PWM,s=200,l=500,y=5250,r=800,bits>=20,match={65}5cb86969feffbc480,countonly'

TheChatty commented 1 year ago

Is it possible to adjust sync length in source code thus non-flex decoders will pick up the signal? I want to use OMG using rtl_433_ESP and an ESP has not got enough resources for flex decoders.

zuckschwerdt commented 1 year ago

These are very simple signals. You can just write a decoder for them. If you are lazy and want something fast just change one of the existing decoders (e.g. generic_motion.c).

We can't merge these simple "doorbell"-style decoders, but you can write/change your own one for ESP.

You do need to change the check also: https://github.com/merbanan/rtl_433/blob/3264d01d65f386529619eecadf1471c4cf42ee5a/src/devices/generic_motion.c#L42-L47

I modified line 43 to check for either 20 (BeSmart) or 65 (AC114) bits.

On my mac with RTL2832U it works.

Ony my ESP with CC1101:

How to output all bits of bitbuffer? Like code = ...?

zuckschwerdt commented 1 year ago

Change char code_str[6]; into char code_str[20]; then change sprintf to

sprintf(code_str, "%02x%02x%02x%02x%02x%02x%02x%02x", b[0], b[1], b[2], b[3], b[4], b[5], b[6], b[7]);
TheChatty commented 1 year ago

Thank you very much for your strong support. It now works very well with RTL2832U. I need to tackle CC1101 further...

One more question: Is there a simple way to convert above codes to esphome raw codes?

Dumping received AC114 stop signal looks in esphome raw format similar to this:

code: [-599, 596, -199, 196, -571, 618, -174, 219, -594, 197, -595, 198, -596, 596, -173, 615, -199, 195, -595, 596, -198, 195, -571, 222, -593, 198, -594, 596, -197, 593, -173, 616, -199, 594, -199, 197, -595, 198, -572, 618, -174, 219, -593, 
             596, -197, 592, -174, 219, -596, 596, -199, 196, -594, 198, -571, 619, -173, 219, -593, 595, -198, 592, -174, 218, -596, 198, -595, 198, -596, 198, -570, 222, -570, 222, -593, 198, -594, 197, -571, 618, -174, 219, -595, 197, -596, 198, -571, 222, -570, 
             222, -592, 197, -595, 197, -571, 221, -595, 198, -594, 197, -595, 596, -173, 218, -570, 222, -594, 197, -595, 595, -173, 615, -174, 618, -199, 196, -596, 197, -596, 597, -173, 218, -593, 595, -199, 593, -197, 593, -173, 616, -223]

This is close enough for matching further signals but it looks like it's not close enough if I send this via esphome. It's not picked up by the orginal receiver.

zuckschwerdt commented 5 months ago

Since this is PWM coded a single 0-bit should be 600,-200 and the 1-bit 200,-600. The +/- is pulse/gap format. Just out output each bit that way.

zuckschwerdt commented 5 months ago

Also you can open https://triq.org/pdv/ then click the plus symbol and choose "Raw pulse data" and paste your example above to see the raw esphome pulses:

esphome-code

TheChatty commented 5 months ago

I was looking for the opposite. Like having a .cu8 sample and convert it to the above raw pulse format.

zuckschwerdt commented 5 months ago

After converting (transform all bits to 600,-200 / 200,-600) use the resulting codes in pdv to compare if you got it right :)

TheChatty commented 5 months ago

I needed to get the bits then converted them with Excel formulas to pulses. For AC114 it is important to send the high preamble (but it was not shown in esphome raw dump... luckily rtl_433 and my SDR did).

For sake of documentation - here are the working codes in esphome raw format:
