In the topic about the Cotec/Clas Ohlson switch the rtl_433 tool was mentioned.

As I have a Realtek RTL2832 based DVB dongle laying around I gave it a try to install rtl_433 on my Pi last night and see if it is of any use.

Following the instructions compiling the software was really easy and without any configuration I was able to detect 433 mhz devices, the RTL2832 dongle was automatically detected. rtl_433 is a command line tool which outputs detected signals in different formats, like json and csv) so the Pimatic log reader plugin could be used to use rtl_433 within Pimatic.

I’m going to play a bit more with it, for now mainly as a tool to detect and debug signals as I’m using homeduino as my main 433mhz device.

I already implemented a weather station protocol which was supported by rtl_433 but not homeduino, but I’ll share those details in a different topic.
