The method I originally proposed is simple, easy, and would be faster and more reliable. It does not require any scripting either. Once you have the plugin installed you can send messages with a single Scrape action. You have more power too since you can send either an event or a more precise command such as "set light X to level Y". But I don't know if the plugin only works with HS3. Maybe this plugin works with HS2 (I don't know), maybe there is an equivalent for HS2 (I don't know), maybe it makes sense to upgrade to HS3 (I don't know).
Assuming you are OK with using HS3 the choice is simple. The creator of the plugin offers extremely thorough explanations of how to install and use his plugin. I'm not sure what the problem is here. The steps to install the plugin are few and clearly defined. Having never used homeseer before at all, ever, I was able to get homeseer working with this plugin generating events in about 15 minutes. I was actually quite surprosed at how painless the whole process was, once I got homeseer installed. Most of that time was spent installing HS3 and trying to figure out how to create a device etc. Once I had homeseer working and the plugin installed, getting VC to send an event took about 1 minute to figure out. Nothing to figure out really since the web page we linked to tells you EXACTLY what you need to send and offers many working examples. Nime5ter also posted a clear example of how to set a device state.
EDIT: Self correction, the installation is only 1 or 2 steps. Download a file and save it to a folder.
