Would be awesome to get the pi transmitting RF signals with GPIO4 pin in HASSOS.
Recording can apparently be done with a cheap RTL-SDR dongle and rpitx .https://github.com/F5OEO/rpitx

See instructions here https://github.com/defcon24bit/record-and-replay-RF-remote that @progbite made. He had a second device to experiment on and use this.

Would be great to only be able to use it on HASSOS so there is no hassle with Raspberry pi OS.

I guess this is perfect to use with all my left over RF 433 devices and especially some RF 868 devices like the air circulation systems in the house. Rolling codes encryption is not point of interest here.

Thanks for including me @jeanbart

I assume the recording code of https://github.com/F5OEO/rpitx is large and replay small. The normal use case is record once, and then replay, replay, replay… So integrating replay as first step would be a great.

I would love to automate my shutter blind (if this is the correct term) and just bought the SDR dongle described by defcon24bit. Unfortunately, I have problems with installing rpitx, as it seems impossible/not easy to get root access on HASSOS. Do you know an easy way to get rpitx running?
