I was planning to add plug wise Switch and Scan functionality to 'my' Homeseer plugin, but it seems that this can't be done natively.
But..... what you can do in general, (not homeseer related)
I added the events license to my Plugwise Source program (50 euro

This script can execute any external program or other scripting command you might find useful. Using an external program enables me to run a Homeseer event or command, but of course you can also interface with any other program....
See screenshots.... Maybe this is useful for anybody. Best regards,
