Radio wave scanner - buuuudzik - 21.09.2016
Hello,
I am searching such device which can monitor radio waves on defined frequency e.g. 433,92 MHz. I want check what was sent and I want prepare the same on some transmitter which is connected to LM via some medium e.g. RS485.
The inspiration of this search was the restrictions of RS485 -> Somfy RTS transmitter in comparison to the pilots which are a lot of faster than this special transmitter. The minimum pause between 2 radio commands "down" is 0,7s. This is not the best especially when I will try send few telegrams in a short time e.g. scene or change slat angle via "step" command. End also there is the channel limitation but this is not a problem. The most important problem is very big different speed of the transmitter(very slow) and the pilots(very fast).
Maybe do you have some suggestion?
Of course I can buy some pilots and connect to their buttons via some switch actuator but maybe there is some other way...

I dont know of any finished products that will do this out of the box, but I've had some success with 433,92MHz devices and getting/sending data with arduinos.

Other options than using an arduino would be to use a raspberry pi with 433Mhz reciever/senders and do JSON or other datacom to the LogicMachine.
These options are not recommended for business purposes as there are no ratings and approvals on your "product" but for home use and testing it will work.

Thanks Sanstrand, I will think about this
