I am currently working on a project. I am looking for a transmitter and receiver that can be controlled from one spot, preferably from a computer, and is able to control hundreds of the receivers with a push of a button. I need something that can transmit around 100 miles and is in a relatively small form factor. It will only be giving a raspberry pie a signal to turn on and off, so it does not have to be anything super complex. Looking to get started ASAP and anything would help and would be much appreciated.
