I'm using an RTL-SDR for 433.92 MHz sensor measurements, but it's only a receiver. For Somfy RTS you could use Pi-Somfy with a cheap RF transmitter, but I haven't tried it yet. If you really want a USB transceiver, there's the RFXtrx433E, which has two transceivers: one for 433.92 MHz and one for Somfy RTS (433.42 MHz). It's not cheap, but it works well (I have been using it for my Somfy RTS blinds for years) and is supported by Home Assistant.
I have done this, and wrote a book about it: https://koen.vervloesem.eu/books/control-your-home-with-raspberry-pi/.
