OpenBK on roller shutter switch: Communication with TuyaMCU and control programming

Hi,

I have flashed OpenBK on my shutter switch and found out the GPIO config. So I can control everything. What I'm still struggling with is the autoexec.bat

How can I communicate with the TuyaMCU and how can I program a rule that prevents relay 2 from being switched on when relay 1 is switched on?

I would be grateful for any information.

Greetings Silas

On the subject of shutter control, we have a good example of a configuration developed by our English-speaking user:
https://www.elektroda.com/rtvforum/topic3972935.html
The above example is based on scripts, we have not yet written a special controller in C, but we plan to create one. This controller also ensures that two relays are not switched on at the same time.

As far as the autoexec.bat is concerned, it is worth taking a look at our examples:
https://github.com/openshwprojects/OpenBK7231T_App/blob/main/docs/autoexecExamples.md
In general, all the documentation from here is helpful:
https://github.com/openshwprojects/OpenBK7231T_App/blob/main/docs/README.md
We also have documentation of the commands:
https://github.com/openshwprojects/OpenBK7231T_App/blob/main/docs/commands.md
Every entry from the documentation also links to the forum via the search engine, so you can find more information on Elektroda.

As far as TuyaMCU is concerned, there were two topics:
https://www.elektroda.de/rtvforum/topic3983631.html
https://www.elektroda.de/rtvforum/topic3985009.html
In addition, we will soon publish a general tutorial on this topic, and try to translate it into German, but in general it is worth looking here:

Hi,

Thank you for the answer. It has helped me a lot. I have now successfully flashed the 2nd device! Unfortunately, I now have the problem that the child lock is active:-(


Has anyone got any ideas on how I can deactivate it?

According to Tuya IOT, pressing a physical button (4x) within 5 seconds should deactivate the child lock on switches; unfortunately it doesn't work or I'm doing it wrong.

Is it perhaps possible to send a command via TuyaMCU?

Best regards
Silas

Do you mean the parental control integrated in OBK? If so, open Config and then Flags, search for the lock flag and deactivate it.

I recommend reading the documentation on the flags:
https://github.com/openshwprojects/OpenBK7231T_App/blob/main/docs/flags.md




Or is it the Tuya child lock that runs on the TuyaMCU? If so, you must send the corresponding variable with the specified value, type and dpID. For this, tuyaMcu_sendState is used:

You can find out more here:
https://github.com/openshwprojects/OpenBK7231T_App/blob/main/docs/commands.md
Do you know the dpID and type of the variable you want to change?

Hi
Thanks for the quick reply. It was the flags!!!

Thanks again for the help and the general work of openBK and the forum!!! TOP!
I will also try to contribute something in the future!
