I picked up a 433 Mhz transceiver kit so I can mess around with a remote controlled power outlet from my PI. Thing is, the two the examples I find for it use the WiringPI library which appears to be defunct.

Is there another way to code with this kit from a PI?

edit - specs are:

  • @Milliways - It's an older B series board running Raspbian/RaspiOS

  • This is hardly a specification of the device you are attempting to connect. Without knowing this no one can answer and the link to the "kit" is remarkably unimformative

    @tlfong01 - I see. Yes, you are correct. Thanks for the link. On the back of the receiver is screenprinted "MX-RM-5V 080408". I thought Millways wanted the type of Raspi I was using. I thought the link to amazon would be enough info for the more experienced to offer some insight.

    Another "wiringpi is deprecated" rumor. Where do these come from? On my RPi 3B+ bullseye, getting wiringpi installed is still done with the normal apt sequence: sudo apt update, then sudo apt install wiringpi. Also know that WiringPi is now maintained by a team on GitHub since Gordon threw in the towel.

Finally ran across a fork of WiringPI for anyone interested. I've been looking for days and not sure why it took a post here before actually finding it. I compiled this along with 433Utils and it's fine: https://github.com/WiringPi/WiringPi/tree/final_official_2.50

  • I should mention, although the RPi_Utils directory compiles, I am not seeing any codes when running RFSniffer. Pretty sure I have the wiring hooked up correctly with the customary RX data pin on GPIO27, and TX data pin on GPIO17. Even using codesend produces no output so something is amiss here. Not sure if it's my hardware or the software at this point.
