All I am looking for is a couple of devices that you pair together.

The first devices should only be able to read values from some standard input source and transmit them in a secure way to the second device.

The second devices, the receiver, should only be able to receive values from a swarm of transmitter and stream values over via USB.

Those devices should be crazy cheap, actually they do close to nothing, very power efficient, open source and without whistle and bells...

No integrated editor (why do I need an editor anyway), no integrated dashboard or data collect services, that can be easily implemented later...

Is there anything similar ?

Edit: USB, not TCP/UDP
