And you need to know what modulation method they use, what data is sent and possibly returned.Paul
Very difficult task to do what you are asking.You will need far more information about the wireless controller, and even then , unless the manufacturer will give you the details of how it works , most wont , you will have an almost impossible task to reverse engineer the protocol used.
Assuming the device is using that frequency, is using an OOK protocol, is not a rolling code, is not encrypted then maybe try using the same methods as one would for decoding weather sensors.A link the the device your talking about may help but if it's the one I found then you may need to capture RF traffic from the pump/mixer as well (if it sends any)
Thanks Paul,Is it not possible to figure that out or is this something that I'd need to know or the project is effectively a non-starter?Ok, that sounds a little more disheartening.I'm up for a challenge but I'll see if I can get any information from the manufacturer first.Thanks.
OF course it's possible to figure it out. Use your spectrum analyzer to look at the transmitted output and determine the modulation method.Then use a matching receiver for that frequency and modulation and record the data output with your recording oscilloscope. The trace will tell you the data coding structure and possibly the actual data stream.Now you can program your Arduino and the receiver to actually read the data with the Arduino and print it on the IDE monitor.And there you go!Paul

You could go cheap and use an SDR dongle instead of the spectrum analyser
