@Lumpy Thanks for sharing that! I posted something similar for those of us who aren’t quite at that electrical level yet, using smart power outlets from Amazon: Smart Shop - activate dust collector with router
The upside of the power outlets is I have a one-to-many relationship where any of my on switches (router, jigsaw, chopsaw, bench) trigger the vac and can de-activate it. The problem I have is remembering to move the vaccum hose now! I need to get it over head and probably do a little project to shunt between various hoses automatically, but that’s outside my reach for now…
