How to use functionNotSupported?

[patrik-malina]

I have several devices that don't support some traits.
How can I use error functionNotSupported in flow/device settings?

Thanks in advace.

Unfortunately, there is currently no way to do this.

There are plans to include some kind of async response like node-red-contrib-smartnora has. See #458. There, the device node outputs a command, your function node handles the command and generates a response (e.g. a functionNotSupported response) and that response is fed back into the system via a response node.

But there is currently nobody working on that. So it could still take months or years before we support this.

Ok, thank you for clarifying.
Hope someone get to work on it soon :)
