[BK7231N][CBU + RF 433] AVATTO WSMD-4 Configuration of RESET button and RF chip on OpenBK

I purchased an AVATTO WSMD-4 four-channel switcher onto which I successfully uploaded OpenBK.

.

.

On board is a 433MHz chip with the mysterious designation 0056

.

The device itself is similar to the one described here...:
https://www.elektroda.pl/rtvforum/topic3989878.html

Unfortunately the config was not extracted during the backup.
I traced the paths visually and with a multimeter, I attach the config...:

.

The relays and buttons work fine but I have two questions.

1. the device has an additional RESET button which is connected to pin 7 and connects the ground, how can I make a short press do the restart of the CBU module and a long press (5s) do the conversion to AP mode?

2. the RF chip 0056 is connected by output 8 (in the picture above number 6) to pin P24 of the CBU, I understand that the RF support is not implemented yet and I will not do anything about it for now ?.

I have moved the post from .com to .pl

Re 1: Button events, set the role of the button as Btn_ScriptOnly. Use the events OnHold and maybe OnClick

Re 2 This is TODO, so to be done only.

Do you have, after all, the 2MB of copy?

Of course I have a backup, I did it twice just to be sure, attached. Thank you.

Ok a can you complete the template with links to photos, topic, forum, etc?
I don't see anything about WSMD-4 https://www.elektroda.pl/rtvforum/find.php?q=WSMD-4 and not here either:
https://openbekeniot.github.io/webapp/devicesList.html
so you could add a separate entry for it

Thanks for pointing me in the direction of the search, I now have the Reset (Pin 7) button set to Btn_ScriptOnly , and in the /autoexec.bat file:

.

....i works as I wanted
I've tweaked the template but I've never added devices to the DeviceList and wouldn't want to mess something up.

I can add, just post the full JSON here and complete the device name, tags and links to the subject and image.

I have corrected the first post with the json file, is that enough ?

Hi
sorry not able to speak Polish and will include auto translated text afterwards.

Also have this type of board with Tuya CBU Chip. May I ask if you desoldered the chip for flashing or just used the soldering pads at the pcb?

Is there a solution for the 433MHz communication? Therefore I´m thinking about replacing CBU with ESP8685-WROOM-06-H4 but just with a short look there will be no simple replacement possible because ESP will need EN pulled high for operation and I´m not sure if special requirements for GPIO8&9 will need some more modifications.

Is there a solution for 433 MHz communication? So I'm considering replacing the CBU with ESP8685-WROOM-06-H4, but after a quick look this won't be possible in a simple swap as the ESP will require a high EN pull-up to operate and I'm not sure if the special requirements for GPIO8 and 9 will be met needs some more modifications.

I didn't desolder the chip, in the picture in the first post you can see the thickened tin on two pins and two solder fields.
As far as I know there is no 433 support yet

@tomik67
Thank you very much. This worked fine with OpenBeken. But now I have the board working on ESPHome because 433 MHz also worked immediately.
