The opposite of presenting a child?

[alowhum]

I'm working on a 433Mhz signal cloner. This device learns new 433Mhz signals, and then allows the user to replay signals.

For each new copied ON/OFF signal pair I want to present a binary switch to the controller. That works fine.

But the user also has the ability to delete the last copied signal.

In this case I would like to tell the controller to remove (or display as disabled) the related switch.

Looking through the API I didn't see any 'internal signal' to do so. But perhaps there is a way?

Are there no clever hacks for this?

If your controller supports scripting, perhaps you can have a special child using that sends child id to delete?

That's an interesting idea, thanks. Perhaps I could also make two children that contain the numeric count of how many devices are operational.

Would this be something that could be relevant to build into MySensors?
