I'm sure there's a way, it just depends on how far you would have to go to make it happen. There are a bunch of articles out there about hacking it. However, for the rest of us it would probably require an open API that you could communicate with to signal the light to flash. If that were available, then yes, it could be done from the TD pretty simply. TD Events can run an external application, so it would require writing a program that would communicate with the API to flash your light, then just have the TD run that program from an event that fires when the level changes. Sounds complicated but it probably could be something as simple as running
curl with the right parameters (I'm making this up of course, the link below is not real):
