What's right to put on bk7231n based IR blaster to make it usable in HA?

Sounds like you’re getting there.
If ClouldCutter doesnt do it, I bet you’re close to getting the timing right with the serial approach. Do the same and then read the chips details or upload something and it’d probably do the trick.

Just in case it’s of any use, there isn’t much difference to what I’ve posted previously, but below is what mines been running for the last few weeks.

Be ware that it seems to be close to some limit (that I don’t fully understand yet)… add more remote codes and you might find it starts to take longer to boot and to connect to HA. So remove or comment out any of mine you don’t want, rather than just adding to the list.
Whatever this limit is, I think it’s what I started hitting when I tried out @WaresMyHass’ trick for getting the recorded codes to show in HA. It’s why I’ve turned off the web server too.
I’ve ended up with quite a list of remote codes in there for controlling my TV and Kodi that I watch everything through. With a smaller list you could use either OK again.

It was too long to post in one message, so I’ve chopping out the codes I’d found but don’t use so had commented out:

I’ve seen a few reports around the forums of the chips being sensitive to power supply (if powering externally when serial flashed).

So worth investigating that side of things if you are having issues. Apparently some of the serial adapters can be poor for this.

FredTheFrog · March 27, 2024, 11:00pm

I was able to successfully use tuya-cloudcutter to this device. Checking out things now…

mad-tunes · March 27, 2024, 11:02pm

Well done.
I thought I’d done it the hard way

Enjoy recording your remote codes

Edit:
Just as I hit submit, I realised there’s a better approach to sending the codes… They should be buttons rather than the switches I’ve been using.

The toggles never made much sense, but they did work OK.
Better version:

Well, the device is on my network, but how to flash it with ESPhome code, I have no clue. The USB-C port on the device is power-only (unless I’m mistaken). More reading to be done, or even 3D-printing a pogo-pin connector for the BK72xx module.

mad-tunes · March 27, 2024, 11:33pm

The port is power-only.

Getting stuff flashed from ESPHome took a little fiddling for me to begin with, but it end up being dead easy.
There’s 1 ‘rule’ - once you flash any OTA or API key to a device, do not lose that key or you’ll be flashing it the hard way again (ask me how I know )

Quick version:
Go to the ESPHome menu item down the left of HA
Hit + Add Device & follow the wizard.
You can skip/ignore anything that gives you that option and for the type of device though - they all add stuff to the YAML, that you have pretty much ready-made above anyway
Either copy the OTA and API keys somewhere else if you want to keep and use those. or ignore them and set blank ones in a minute.
Copy/paste what I’ve put above, replacing everything thats already there
Copy/paste the keys back in if you want to use them, or set your own, set them in a Secrets file like I have, or leave them out entirely.
Set the devices hostname (that it’ll use to upload to over wifi) as name on the very first line
Set any Friendly Name you’d like it to show up as in esphome
Set your own Wifi creds, hit Install and Wireless.

FredTheFrog · March 27, 2024, 11:34pm

You are a VERY helpful and generous individual. THANK YOU!!

mad-tunes · March 27, 2024, 11:36pm

np. it’s only a little typing mate. It’s a learning curve I’ve only recently gone through myself, so I know what I got hung up on at least

…and that was all assuming you’ve already installed the ESPHome add-on, if you havent then do that first

Once you’ve got something uploaded to it through esphome, it should be automatically discovered and you should see a notification about a new device being found. Click that and then it should show as a device, where you can click on remote ‘buttons’ and make it do stuff.
There’s a Log option under the main ESPHome menu down the left, that’ll show any codes its received so you can then use them to create your own buttons for your own stuff.

Just out of interest… what use are you hoping to put it to, what will you be controlling?

FredTheFrog · March 27, 2024, 11:46pm

I have an LG television to control, and possibly a few other devices to add later. Fortunately, I already have all the hex codes for the functions I need, having done an IR blaster previously.

mad-tunes · March 27, 2024, 11:52pm

Excellent, as long as you know the format the codes are then it’ll pretty much be renaming them and copy paste the codes.

Just in case you haven’t already found it, this might help if it needs anything different to what my stuff uses

For LG, it looks like each ‘button’ will need something like this:

  - platform: template
    name: YourButtonName
    icon: mdi:wall-sconce-flat-outline # icon name from https://pictogrammers.com/library/mdi/, or remove/comment this line if you don't care about an icon 
    on_press:
      - light.turn_on: status_light
      - remote_transmitter.transmit_lg:
          data: 0x20DF10EF # power on/off
          nbits: 32
      - delay: 60ms
      - light.turn_off: status_light

The light. and delay: lines just make the blasters blue LED flash when its sending codes. You could remove or comment them out if you dont want it to

FredTheFrog · March 27, 2024, 11:55pm

I’m currently following the instructions here to install ESPhome with LibreTiny on the RPi running tuya-cloudcutter. Specifically, steps 10 and 11.

Run the docker container to enable the ESPHome Dashboard with
sudo docker run -d -v /opt/esphome:/config:rw -v /etc/localtime:/etc/localtime:ro -p '6052:6052/tcp' --name libretiny-esphome ghcr.io/libretiny-eu/libretiny-esphome-docker:latest
Open a browser to your Raspberry Pi IP on port 6052. Example http://192.168.1.9:6052 This will allow you to build your ESPHome firmware for the device.

mad-tunes · March 28, 2024, 12:01am

ah, a bit I didn’t do… Is that in the section thats labelled with ‘NO LONGER NECESSARY’?

Ignore me, there are two sets of 10 & 11

FredTheFrog · March 28, 2024, 3:12pm

Well, I double-checked my connections, and P16 (TXD) had lifted from the module. Unfortunately, there’s no brass/copper left on the module in that spot. Okay, purchased two of them, so wire up the second, where P16 is available. I can see ltchiptool sending requests to the bk7231n module, and the module is echoing them back, at least that’s what the LEDs on my UART say. But it never connects. I’m trying all sorts of P1 RST and P3 CEN to GND tricks, and none of them are eliciting any kind of positive response from ltchiptool. Just frustrating, is all.

mad-tunes · March 28, 2024, 5:27pm

Sounds a little rough, but maybe not the end of it with either…

Did you get anywhere with cloudcutter on the first one?
If you got its firmware replaced at all, you’ve still got a good chance.

When I got mine flashed after soldering to it and using my USB/serial adapter, it did take a little messing about timing-wise. Wish I could remember the ‘trick’… connecting to it was pretty reliable once I was getting it right.
Assuming we’ve got exactly the same thing hardware-wise, it really should be possible to do similar with your second one.

FredTheFrog · March 29, 2024, 2:22pm

Okay, so after finally getting a decent night’s sleep, I was able to find @ferbulous video:
https://www.reddit.com/r/homeassistant/comments/zkl0n2/flash_ota_using_tuyacloudcutter_tuyaconvert_for/

Until this morning, I wasn’t aware tuya-cloudcutter would actually flash something else other than the cloudcutter code. Might be able to get further with it this morning, after all…

Nope, tuya-cloudcutter goes through the motions, finally fails with this (tried several times, all the same):

 $ sudo ./tuya-cloudcutter.sh -v -f ESPHome-Kickstart-v23.08.29_bk7231n_app.ota.ug.bin -p aubess-ir-remote-controller

DOH! it SERIOUSLY helps if you remember to prefix that command with ‘sudo’, as there are a lot of nmcli network manager commands in the scripts requiring superuser access.

What it looks like when you execute it successfully:

Found access point name: "A-EBB9", trying to connect...

Flashing should be complete.  It takes about 15 seconds for the device to reboot and verify the flash was valid.
Please wait about 30 seconds then look for signs of activity from the firmware you supplied (either watch for AP mode or check if it joined your network).

Now, after this, the kickstart firmware will setup a wifi Access Point. You join it, select the wifi SSID and provide the password it needs, and it joins your network, whereupon you can load firmware using ESPHome over-the-air. Pretty neat. Except: the device has some kind of problem rebooting. It just flashes the led steadily, and never connects to the wifi.

I have a couple of ESP-12F modules, I think I’ll be transplanting one to this board very soon.

Mahko_Mahko · March 29, 2024, 11:25pm

Did you try a hard reboot and then reflashing with a basic config including adding a static ip in your new config?

Also beware that I’ve seen some reports of LEDs flashing until you actually integrate it into HA.

mad-tunes · March 29, 2024, 11:31pm

Hard reboot (pull its USB cable for a minute or two, then reconnect it) is well worth it if you haven’t already.
After that, does it start its own network, do you see any new wifi SSID?

Kickstart did that for me, back in the first post in this thread.
I don’t know if or how cloudcutter might give it your wifi creds tbh. If it was given wifi creds, but it’s failing to connect to your wifi, you might have to wait a while for it’s acces point to show up.
If you do see any new SSID, connect to it leaving your wifi using DHCP first, but you might have to set a static IP on whatever device you’re connecting to it with.
Use its kickstart web page to give it your wifi creds (again) and hopefully you’ll be up and running.
Scan the IPs on your network to see if it shows up, there are tons of little apps to do that on a windows machine, and I’m sure there are plenty that’d be similar for your Pi if you’re still using that.

I’m not sure what kickstart does with the LED exactly, it may well keep flashing until it’s connected to the esphome api. It’s a good indication the things running different firmware now at least!

Sounds like you’re really close, I bet you’ll have it running and connected in your next message or two

Orthobot · April 19, 2024, 7:35am

Hi @mad-tunes.

Thanks a lot for doing most of the grinding for those of us with IRblasters on Bekens. I have a similar device, with a different version of the BK chip. I’ve already gotten ESPHome on it, together with the correct pinouts. It transmits and receives properly i think?

My problem is figuring out how you get it to learn codes from remotes and subsequently reimplement those codes back into the config as entities. I’m outputs like this for my Daikin HVAC remote

Thanks!

mad-tunes · April 19, 2024, 11:35am

I found there’s really two parts to it… figuring out what kind of IR codes a device uses and then capturing whatever you want to use.

I’d try the shorter codes first (JVC, LG, NEC & Pioneer from your log), adding a button for each so you can run down the list and try them easily/quickly.
You can see how to send each type of code here.
Hopefully you’ll find one of the codes listed make your HVAC respond.
If none of those do the trick, try the same with Pronto.
After that you might have to resort to Raw.
Pronto and Raw seem less reproducable though, I found it best to capture a bunch and use that to find whatever’s most comonly received, aim for whatever looks most average.

That should let you figure out what kind of codes’ll work, then you change the dump: all line to capture just the relevant type of codes and capture other remote buttons from there.

The learned codes chunk is a really nice idea, but I found I hit some kind of size/memory limit about the time I was trying it so I didn’t end up using it. It’d need repeating for each type of code too, which I never ended up doing.

Edit:
It might be good to try it out with something that’s more likely to have a clear type of code first. HVAC stuff could use all sorts, but something like a big brand TV should be easier to get going, and would prove what you’ve got there works before getting too tied up with something more awkward.
