Regarding my current setup, there is not that much to draw. Just a wireless, battery powered push button which sends a 433 Mhz signal to a battery powered chime. So nothing I can or want to reuse from that setup.
This is what I'm trying to achieve (same setup as
@moista as mentioned before):

The push button is the DB1, the relay is a Satel 10-13vac relay:

I haven't connected a chime yet, but since the relay only switches on or off that doesn't really matter for this test. Problem is that once the IR LEDs turn on, the relay swiches on and doesn't turn off again until I cut the power from the DB1.
