openBK ota not working

[klmi]

Hi,

i successfully flashed an bk7231n with openbk. now i'm trying to include it in esp home with ota update but it doesn't accept the file as suggested here

(renamed bk7231n_app.ota.rbl to bk7231n_esphome.rbl, and all other files, non worked):

Also flashing it directly to the chip via ltchiptool oder bk7231flasher doesnt work...the chip just starts, prints a few lines about itself and gets stuck there

any idea why ota doesn't work? is there a way to some logging about it?

As said in the migration guide, the file has to be named OpenBK7231N_esphome.rbl, not just bk7231n.

Hi, I am also trying to migrate from OpenBK. But I can not find the RBL file in the build directory (libretuya-esphome\.esphome\build\{devicename}\.pioenvs). I even can not find the ".pioenvs" folder. Do I have to enable this somewhere in ESPHome?

The folder is created as soon as you run the esphome compile command. The program needs to be compiled first, only then the RBL will be available. If you'll having issues with getting the folder to show up, you can try ESPHome-Kickstart, which has .ota.rbl binaries that you can use. After that, watch this video (start at 8:17) to see how to proceed from then.

Thanks for your help. I'm using the Home Assistant Addon LibreTiny ESPHome and unfortunately there is no Compile button anymore. So I used Portainer to open a terminal in the container of the addon. After executing the command esphome compile {devicename} I could find the RBL files in the .pioenvs folder.

I could also flash the RBL file and now its working 😃 Thanks again.

Well, that's not exactly what I meant, but I'm glad it worked.

The files generate after compiling the program, which equals to pressing "Install" in home assistant. I previously assumed that you were using the command line. After compiling in HA, you would find the required files using Portainer.
