To be honest mate i think your really going to struggle to find anything that will do the job as you described.
Firstly if your having an automatic door press the the switch it would have to be a fairly heavy duty one that could withstand the constant battering the door would give it. Not something wireless equiment is known for.
Also switching it wirelessly would mean the inclusion of transmitters, receivers and relays to switch the light. And then there would have to be hard wired cables from the board to the relay, and from the relay to the light. Not including if you want to switch the light from a normal position aswell.
Don't get me wrong there may be an easier way to do it, maybe the automatic door company have an intergrated system for there doors you could buy. But i've never seen one, like i said i think you may struggle with this.
Hope that helps a little anyway, let me no how you get on. I'd be interested to know if you find a way to do it.
