B1 to B0 helping tool

[gerardovf]

After learning how bit bucket works from here https://github.com/Portisch/RF-Bridge-EFM8BB1/issues/23 I decided to prepare a python script to help calculate the right 'B0' message to send using 'RfRaw' command in Tasmota from the received 'B1' sniffing message (rename file from 'BitBucketConverter.txt' to 'BitBucketConverter.py'.

BitBucketConverter.txt Do not use this version, it's too old already!

In the command line give the 'B1' message string and the retries value (in decimal): i.e. BitBucketConverter.py "AA B1 04 07EB 0157 00FD 3EBC 010101010101101001010101101010100103 55" 20

Command Line : "AA B1 04 07EB 0157 00FD 3EBC 010101010101101001010101101010100103 55" 20 'RfRaw AAB01C041407EB015700FD3EBC01010101010110100101010110101010010355'

the remote has three four bottom

this is the control remote im using REMOTE like in this link: https://turkish.alibaba.com/product-detail/6-0m-3-0m-large-size-retractable-full-cassette-awning-with-led-60646476303.html

OPEN 2.CLOSE STOP 4 . LIGHT ON/OFF I have the rf bridge v2 succesfully installed latest tamota and upgraded the latest firmware ( RF-Bridge-EFM8BB1.hex)

while using the RfRaw AAB155 and pressing the buttom few time 3-5 secs i get the folowing codes:

thank you very much in advance for any guidance on this issue!

[jotadominguez]

This same this is happening to me, the first try work right away, and then i kept trying the other B0 and none of them worked. And the one that worked, didnt work any more! :(

Any tips? @Portisch I have a 3 button remote SCT-R1, brand TUBE

[yortiz1979]

I just dropped the idea since i did not received and help or advice in the forum and i never found any solution! If you find something please share! And good luck!! On 27 Feb 2020, 4:09 PM +0000, jotadominguez notifications@github.com, wrote:

Any advice for https://github.com/Portisch/RF-Bridge-EFM8BB1/issues/31#issuecomment-489406119 ? I have similar problem.

For anyone who want to parse B0 from B1 data, please find my node-red flow here, which I reverse-engineered from the BitBucketConverter.py. Since the pyhton3 functions nodes made my node-red crash.

B0 builder node-red.txt I wanted to parse this raw data to detect protocols (like pilight or rtl_433, but no luck yet)

I was able to reproduce the command, but not to decode it from raw commands. I found out that I had 2 action (the store) remotes from Flamingo (KAKU sort of) which did respond differently, 1 was decodable by portisch, but the other was not, while it was able to being decoded by pilight (with usb-arduino-nano-433 decoder)

Unfortunately I was unable to connect raw output to a nice decoding-script in node-red (like Pilight or RTL_433) in order to decode all my store-bought 433 remotes

@jhonniedj ah apologies I misunderstood. I thought you was mentioning you couldnt get your nodered flow to work. I am facing issues with it!

20220623_191610.jpg

ooh the node-red B0/B1 conversion was working.

According to the error I guess the input from mqtt is wrong (inputting from an empty string or null/not-string or so), does it work with the test-inject-node? Do you have an example of the input to the Function node? (with a debug node)

[cook1emr]

@jhonniedj I got the same error from the test Inject node

See the input with same error around the function.

[jhonniedj]

@jhonniedj I got the same error from the test Inject node

what version of nodejs and node-red are you running?, it could be that replaceAll is not implemented yet, maybe .replace(/ /g, "") will work in stead of .replaceAll(" ","")?

[cook1emr]

Hi looks like 14.8 node.js, looks like i need node.js 15, however i cant work out how to update the docker container for that

changing to replace does work though

[peterchs]

The online tool is working again now https://bbconv.hrbl.pl/ May need to strip out the time, so the entry is like: {"RfRaw":{"Data":"AA B1 05 02B2 058C 0064 01CC 0FB4 481A38 55"}}

Hereby the file that should resolve the "TypeError: szInpStr.replaceAll is not a function" error: B0.builder.node-red-without-replaceall.json.txt (I replaced the other 2 functions also with .replace, apparently .replaceAll was used on 3 places)

As you say, still down. I'm a bit lost without it, I guess I'll have to try to work out how to get the Python script running...

Still down, bumping so it goes back on someones radar.

convertB1.txt I made a nodejs file to convert. If you rename convertB1.txt to convertB1.js, and install nodeJS, you can run it from command line like this:

node convertB1.js

Then the program needs a B1 string, that will be converted to a B0 string. Does that help you out?

YES! I tried a whole bunch of online Python websites to run the original code. I installed NodeJS on a Mac and ran your code.... and it only took a few minutes to find all 3 codes for Ch2, which were needed for a new blind.

Thanks!

@Portisch: is is possible or convenient to put this code on the main README.md or wiki to help other users? For the NodeJS, and the node-red-flow files. They have the same algorithm (copied) from the Python scripts.

@jhonniedj Thanks! I was just wondering if @Xerus-de made any modification on the previous node,

[Xerus-de]

@jhonniedj Thanks! I was just wondering if @Xerus-de made any modification on the previous node,

Hi, I could share my Node-RED flow with only. It contains only little modifications of the node of jhonniedj for input and output in Node-Red.

@ jhonniedj: would this be OK for you?

[Xerus-de]

@Xerus-de will you be so kind to share your nodered flow? Thanks a lot!

I think @Xerus-de means this one: #31 (comment)

I generated a new variant for Node-RED, based on your node. The B0 value will be directly displayed after pressing a button on the remote control.

Yes absolutely, no problem! As long as the knowledge is commonly shared i'm happy! I merely copied the algorithm from the Python script and translated it to javasript/node-red/nodeJS.

[jkaberg]

Wouldn't it be more convenient to just create an simple HTML page with the JS code that could be hosted on Github pages? That way it's easly accessible and everyone benefits :-)

Anyways thanks for shareing!

Like this? --> convertB1.html.txt (you have to rename the attachment convertB1.html.txt to convertB1.html)

I think hosting this would be best on this github? maybe the contributers of this page want to host it @ the wiki's? I cán host it elsewhere if there is no other way. (like this: https://jonajona.nl/convertB1.html)

Hi Folks, I am no techy enough to understand everything that's being discussed here, but I get the feeling that many of you would be able to solve my problem easily. Perhaps even offer some education or advise? This is my case: I have a Sonoff RF Bridge flashed with Tasmota 13.3.0 and Portisch v0x04 The bridge works well and I use it to read data from various door and window sensors using rfraw 166 But all my attempts to read data from various brands 433MHz remote controls, fail. If I use rfraw 177 I can read B1 data (plus a lot of random noise), but I do not understand how to move on from there. I've used the BitBucket converter https://jonajona.nl/convertB1.html but I do not understand what to do with the output B0 string.

I have searched the internet up and down, but all I find is way to techy for me to digest. Could someone please guidance as to how I can go forward?

Many thanks in advance 👍

Great job, then you're at 95% of the process. Just send your B0 String with the rfraw-command like this: rfraw AAB0230408017C046A0BCC23783818190908181908190909090908190819081818190909091A55

I'm not sure I understand. And I don't dare to try unless I understand. Can you briefly explain what is suppose to happen if I type rfraw AAB0230408017C046A0BCC23783818190908181908190909090908190819081818190909091A55 at the console (cause that's what you mean, right?) What good will that do? I want to be able to parse incoming key-press from the remote to Home Assistant via my MQTT broker. Will you advise help me in that direction?

Hi,

I also use 177 to get the AA B1... response from the remote. This B1 data needs to be converted into the AAB0... value which can be sent by console or MQTT to emulate the button switch on the remote. Use in console following command : rfraw AAB0... For MQTT: send AAB0... payload to _cmnd//rfraw_ Now you can emulate the remote.

If you want to recognize an incoming key-press from a remote you need to find rules in the B1 response string which you can use for triggering other things in Home Assistant. You can do this by MQTT: _tele//RESULT_ If your remote uses rolling code then you will need more than one rule for one button.

Good luck!

Well, thank you 😊 But using rfraw 177 permanently isn't feasible. The RF-Bridge picks up too much random noise. My understanding was that the purpose of the rfraw 177 mode was only meant to be experimental - to really let everyting in without any decoding or filtering at all (come what may). So even though I can sniff the buckets (B1) from my remote, I need a way to teach the Bridge how to recognize and read those keypresses in rfraw 166 mode. But in that mode, as it is now, the Bridge sees nothing at all when I press the keys on the remote. So the question is; How do I make the Bridge able to read the 433MHz protocol coming from the remote, in rfraw 166 mode?

[cook1emr]

As I understand it, you need to decode the protocol and then recompile the firmwire. https://github.com/Portisch/RF-Bridge-EFM8BB1/wiki/Decode-0xB1-sniffed-data

I have never been able to achieve it. Looking forward to anyone with a more detailed guide/understanding

[oywino]

I did manage to successfully sniff the data sent by my RM433 Sonoff remote control, and I also managed to make HA act as a virtual remote control and send valid keypress data via MQTT and my Sonoff RF Bridge to control the end-device properly. In my case study this was a Sonoff D1 dimmable light switch. So, I'm still not able to read when keys are pressed on the remote, but I am able to pretend being a remote. 😊

I also reached this stage, would love to be able to go that extra step and intercept remote presses rather than just emulate them.

[oywino]

Yes, we need to "lure" someone out who knows how to analyse the B0 data strings, extract the header data fro bucket numbers and length, and plug these correctly into the RF_Protocols.h file and compile it. I made some attempts to analyse my data, but I gave up. I was confused by the fact that when sniffing, several keypresses gave me these strings, which all works when I play them back:

AAB0210308030200C81D6A2818181909081909090819090818181908190909081909090955

As you can see - the header data for count and length vary between them, still all works correctly since the payload is identical. I found that it's the ninth byte in the payload that's actually the command. Changing this byte value from 90 to 81 results in an 'off' command being sent instead of the 'on' command. Thus I can toggle the light switch by changing only this byte.

[jhonniedj]

I'm not sure if i'm the one you wanted to lure-out, but if I take a look at the code that I translated to Javascript from the official python-file BitBucketConverter.py (below) together with the the decode-page on: https://github.com/Portisch/RF-Bridge-EFM8BB1/wiki/Decode-0xB1-sniffed-data. and disect it, then I see B0 and B1 are almost idenitcal, except B0 containcts 2 extra bytes:

• 1 for message length
• 1 for amount of repeats

note: This is a hex-representated string, so "AA"(as a string) represents to 0xAA (2-byte hex) (mind the string to hex conversion in hex2string, which I always find tricky to implement, since it is easy to mess up when

===Example B1===

AA B1 04 017C 046A 0BCC 2378    3818190908181908190909090908190819081818190909091A 55

And to apply my explenation with your examples:

Which concludes that header, message-length, repeats, buckets, RF data is always the same. The only (relatively small) changes are in length of bucket, that would probably be measuring-error, and can be ignored (hence the fact that all of them are working)
