Looking for general guidance on RF home automation - I want to be able to copy the open & close commands from RF controller of electric shutters, so that I can have my arduino operate them. Is there an RF transceiver board & library that I could use to scan the code and then replay it? If not could anyone point me in the right direction?
If You can post a link to datasheet or technical manual to the device involved it would make it more clear.
Thank you for the reply. At this stage I'm just looking to gather general info and "in principle" advice. I can say that the remote is RF, and operates in the 500MHz-900Mhz range, and the packets are not encrypted / do not cycle. In principle is there a board that could 1. receive the signal from the remote 2. copy it and save it to memory 3. transmit the saved signal. I appreciate that it will be more nuanced than this, but I don't want to waste anyone's time with detailed specifics, the project might even be outside of my ability range... I've been able to achieve scanning and repeating IR codes quite easily and there are boards and libraries readily available for this, but I couldn't find any simple solutions for RF - perhaps because it isn't that simple... Ok, thanks for your time.
finding unknown frequencies: tinySA. tiny spectrum analyzer.
bottom line: a receiver which scans through a selected range of frequencies and scans a horizontal line across a display. An RF signal on the frequency of the moment makes the line move up vertically. when you find the frequency of the transmitter, enter it into a scanner for demodulating and copying.
a clever guy can find many uses for a tinySA, but they are not for everyone.
Thanks. I've just realised that I've been a bit dumb. The manufacturer sells spare remotes for $20. Seems to me the simplest solution would be to get a spare remote and de-solder the pushbuttons and replace them with transistors driven by digital output pins of Arduino. Job done, and I don't need to get involved in RF. Don't know why I didn't think of this before, but I guess talking about it helps!
Using opto couplers frees You from ground problems.
If your remote device was legally sold in the US, it will have an FCC id tag on it. Google will find all available information on the device by searching for the tag id.
Equally so would keeping the buttons in place and using a servo motor to push them, lol
Solenoids?
