## Learning of Commands with custom Firmware
In order to learn Buttons from your remote, go to the Console of your RFBridge.
There, enter rfraw 177 and push the buttons on your remote. Repeat each button 2-3 times, as the signal may be different for each try.
This will give you a so called B1 code of your button, which needs to be converted to a B0 code (see below).
## Sending of Commands with custom Firmware
The commands learned with the hacked (Portisch-)Firmware **cannot ** be stored in the webinterface. Instead, they must be sent via MQTT:
`mqtt=">[broker:cmnd/sonoff-8E8329/Backlog:command:ON:RfRaw AAB0210314016703F924180101011001100110010101100110011001010110010101100255; RfRaw 0],`
Refer to [this](https://github.com/arendst/Sonoff-Tasmota/issues/3973) issue for further information
## Interactive B1 to B0 tool
Here ([link](https://github.com/henfri/bitbuckedconverter/blob/master/BitBucketConverter)) an interactive tool was developed to learn Commands/Codes.
Process:
-Run rfraw 177 in your SonOff console -Push all your remote (each Button 2-3 times)
-Save everything from the console that happened after rfraw 177 to a file, e.g. console.txt
a) Run bitbuckedconverter.py -f console.txt
b) Run bitbuckedconverter.py -f console.txt -e
In case of a) each line of console.txt will be converted into a B0 string and displayed
In case of b) each line of console.txt will be converted into a B0 string and send to the Bridge.
Then:
* if the device reacted as expeced, you can enter a name of the button (e.g. "light")
* else enter nothing to try the next
* repeat this until all lines have been tried
* The tool will create a list of buttons -and their B0 codes- that have worked (i.e. for which you have specified a name)
* In the end you can test all of these codes

(if you prefer the non interactive version)
After learning how bit bucket works from here [#23](https://github.com/Portisch/RF-Bridge-EFM8BB1/issues/23) this is 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'.
