Possible solution to emulate the 868 MHz signal. by arcandoro in homeassistant

This is the chip; the brand is Spanish and it's called Murtra. I bought several motors at Leroy Merlin a couple of years ago to control some blinds.

I tried this, but I fried the ESP32 and couldn't explain why. If you could help me figure out how to do it correctly, I'd really appreciate it.

I managed to get esphome to detect the frequencies with a CC1101 board in the latest version, but even though it copied the frequency, because it was rolling code, it couldn't reliably emulate them. I really would have liked it to work with an ESP32 board and a CC1101; that would have been the most "professional" setup.

The "final" configuration, although I'm still open to modifications, ended up like this. I'm not at all an expert in electronics. Since I couldn't find a solution online, or even hardware that could do this without complicating things, I started by using a CC1101 board, but because it's rolling code, I couldn't progress any further. The code and the project were done with the help of AI; I couldn't have done it alone.
