somfy-esp8266 VS Pi-Somfy

Yep, I have somfy working with HA using the ESP and software from this: https://github.com/aszopko/somfy-esp8266

I have 2 blinds controlled by remotes of this type: https://imgur.com/WJSpnjt, this should be Somfy RTS. I have found this: https://github.com/aszopko/somfy-esp8266. This seems to be just what I need. One 433.92 MHz RF emitter module, and a bit of soldering to replace the crystal to a 433.42 MHz. That sound doable. Do you confirm that this is correct?

I use this with a raspberry pi. You can set up scripts or a http call in home assistant to control the blinds

An old raspberry pi 1B was used as a dedicated server for Pi-Somfy which allows me to remote control my awning from homeassistant.

I have Somfy blinds throughout my house that use the RTS one-way radio control. Rather than spending more on Tahoma box(es) I have a couple of these set up. Works like a charm.

I'm currently trying to modify a FS1000a transmitter for the Pi-Somfy project which basically allows using a raspberry pi and a cheap modified transmitter to control somfy shutters over a webinterface/mqtt etc. The modification is simply swapping the 433.92MHz oscillator for a 433.42MHz one.

I'm thinking about just moving to python+RPI with this project instead, but perhaps I'm missing something obvious.

If you have a RPi laying around: https://github.com/Nickduino/Pi-Somfy

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.
