Take a look at CoAP[1], an open IETF protocol for IoT.
You can make your hardware accessible through "resources", it's restful.
So a simple GET on the led resource returns the status of the led,
POST/PUT a new status to the resource can trigger the led.
Clients can use "observe" to get sttus changes of a resource.
For python2 there is txthings[2], based on twisted.
There is a new fork for python3 based on asyncio called aiocoap[3], with
no extra dependencies if python>=3.4 is used.

Futhermore there is a plugin[4] to access CoAP resources directly in
Firefox.

cheers,
Florian
