I am trying to control my electric blind (elero brand, controlled by this remote) from my RPi4, and while I'm fine tinkering with anything on the software side, I must admit my knowledge of GPIO and RF stuff is close to nil.
Much like this previous poster, I've found out that 868MHz RF transmitters are a lot less common than 435MHz. And of the ones leftover, I struggle to confirm which ones might let me capture and replicate the signals sent by my remote…
Among (local) online options, I found:
LoRa RF transmitters ostensibly geared at Arduino (but I guess could be wired to the RPi4 GPIO ports?), but also specific to LoRa protocol, which doesn't seem to be what my blinds use (?)
Waveshare LoRa hat which would take up all my RPi4 GPIO ports… Also: still LoRa…
Various boards and USB gateways to the "enocean" protocol, which I'm assuming also wouldn't play with my random other-brand blinds…
Any guidance on what type of RF transmitter I should be looking for, and what the next steps might be to hook it up to my RPi4 and replicate existing signals?
