Mine works great for the garage door, but I wanted to integrate it with my HA system. Like to arm the system from the car, or to turn on lights and stuff. That will require a receiver. I found this one:

but I will have to find my own power supply/wall wart since here in the US 230V is kinda hard to come by. I don't know if there are alternatives (still looking), and I'm not really sure how it works. I see the "output channels", but it doesn't say if they are just NO/NC contacts or if they are meant to be connected to some proprietary homelink device. If they are just NO/NC connections, I can definitely hook it up to my security system.
