UFO-R11 IR blaster (zigbee)....decoding broadcom IR messages

Hardware
1

I am trying to figure out how to decode the IR messages received by this IR blaster. It appears to be a broadcom thing.

I found this broadlink-ir-converter and the decrypted messages for the same button press on the remote seem close but are not 100% the same. Maybe the decryption key is wrong or the algorithm has been slightly updated.

The encoded messages in the z2mqtt log seem to be base64 so I converted that to hex and then ran that through the decoder. Does anyone know of another decoder I might try so I can make a remote for my AC?

I know for simple remotes I can just resend the encoded IR message, but my AC sends information about the entire state of the remote and this is where things are falling down.

That sounds about correct. :white_check_mark:

While I personal never used it the ESPome IR Remote Climate component (or it’s source code) might help you to understand your system better :point_down:

thanks, I will take a look at the ESPHome stuff.

I know it’s been 2 years, but did you ever discover anything? I’m in the same boat, and I’m trying to figure out what I can.

Of course after looking for answers for the last couple weeks, I finally decide to comment on an old thread. Only to then moments later find the answer. If anyone else stumbles across this thread looking for the answer, the data is basically just raw timing data compressed with FastLZ. Mildsunrise the first that I saw that figured it out, and she posted a python script to be able to generate your own Base64 codes.
