Sending IR with CUL
I finally had a positive breakthrough with the CUL-stick. It has been working fine for sending to all supported protocols on the 433MHz band for controlling switches. But this band is also used for IR-extension devices such as the PowerMid, which is used to transmit IR remote control signals via radio. If I could tap in to their protocol, the CUL-stick could also be used as a generic IR-transmitter via a PowerMid! And now I finally got that to work. By modulating the mark pulses with 40KHz, the signal is received by the PowerMid receiver and sent as IR signals! This makes the CUL stick kind of a Swiss army knife of home control – both light switches and any IR remote controlled device can be managed!
