I followed the link below. I used the Method 1 that he listed for Configuration and the the python-broadlink method for learning the IR codes. I also set it up with the MQTT method as a backup but I do not currently use it because I would have had to create a directory structure to match the MQTT messages. For my specific setup that would have created 2 or so hours of folder creation and a single text file for every IR code I needed to use. Using this method to capture the IR codes is the easiest way IMO. I was able to quickly and efficiently learn and toss all my IR codes into a broadlink.map file by repeating the same three quick commands.
From that point I ended up creating my own personal widget for the remote based off of the weather widget tutorial and several posts in the page below to help with understanding oh-links and badges.
to learn codes - the best way is to use this utility Broadlink Manager download | SourceForge.net
But what is the best way connect this codes in OH3 i don’t know. Year ago on OH2.5 i do this manual but that was complicated , you must wright many text files. I really interested how can we do this from OH3 interface, with his new abilities
Best way for OH3 is via the Broadlink binding. Install the binding Broadlink 3.1 which is a few posts above. The ActionCommand that I have called CABLE_SELECT(or CABLE_POWER depending on what photo you look at) is the command that correlates to what is in the broadlink.map file.
Thx for the help, I instal broadlink bunding, it work, but can you pls do a more open tutorial. Something like how to add custom RF/IR code and shoot it from oh3, in a step by step way:
where you put map file
what you write in map file
how you create the property links like in your picture
how you shoot this property from “Model” (for example I do relay control from this menu can I add here “custom code” and shot it from here?)
Hello.Tell me please. I have broadlink rm4c mini.I can’t read the codes from the remote for the file broadlink.map.I tried the bridge broadlink but it is only suitable for RM1/2.Tell me please how to read codse. perhaps there are other ways.
Have a look here.
I also got a RM4C Mini in production controlling my TV and Mibox.
The guide should enable you to record your IR commands.
You can then use them in openHAB/MQTT as you need to.
The broadlink.map file goes into /etc/openhab/transform and you write in the .map file the commands like:
start=IRCODE
You can then use the “start” command to execute the IR code via openHAB via the broadlink command channel.
There should be enough information in this thread to configure openHAB by now.
Have a read through it and let us know if you need further information.
I used the method outlined in linked thread via Teach Remote Codes leveraging broadlink-mqtt, whereas also used python-broadlink. Both worked, just follow the instructions of said thread or their respective github repos.
I have a Broadlink RM 4 mini on Openhab 2.5. I got a few IR codes that I learned with the Python library and it worked a couple of times. However now nothing happens when setting something in PaperUI and in addition the following shows up in the logs:

It does show as online in PaperUI.
Any suggestions, what I could do?
I had some issues with it so have stopped using it for now. It would work to start with and then stop getting updates. I need to add some more logging but it seems like the auth starts to fial
My knowledge of Python is limited but I think what is happening is:
checksum = sum(packet[0x08:], 0xC0AD) & 0xFFFF
As you say, sum up all of the bytes from 0x08 onwards and add 0xC0AD.
Bitwise AND with 0xFFFF to leave just the 16 least significant bits (throw away the large part of the sum)
packet[0x06] = checksum & 0xFF
Bitwise AND the checksum with 0xFF to leave just the 8 least significant bits (that fit into the least significant byte of the two byte checksum at position 0x06 of the packet array)
packet[0x07] = checksum >> 8
The >>8 shifts the 16 bit checksum 8 bits to the right, leaving the most significant byte of the original checksum as a single byte, which is then put into the most significant byte of the checksum at position 0x07 in the packet array.
So overall, it’s summing up all of the numbers, finding the least significant 16 bit part of the sum and splitting it into 2x 8 bit bytes to go in the 2 bytes of checksum in the packet.
I have all my configurations in Items files etc too but, for Things, it’s far easier to use the OH3 Things to stop spurious items appearing in the Inbox.
