No Wi-Fi For The Pi

How can a Raspberry Pi be made to talk to IoT devices over low power FM rather than Wi-Fi? Looking for distances under 100 ft.

There are many low power radio modules in the market, which can be interfaced via the RPi’s serial port and/or GPIO pins, and which will allow point to point communications over short range (have a look at www.radiometrix.com; other suppliers are available). But, so far as communicating with existing IoT devices, you may have some trouble, since you will need a communication device compatible with whatever you are trying to communicate with.
