The still seems to be is a persistent misconception that the home-brewn
receivers need polling or cause heavy CPU load. No they don't. All of them
are IRQ based.
It's the commercial solutions like gpio based IR that need polling.
For transmitters it's a different story, but you don't transmit 24h/7.
