it is possible to control the Gpio of a raspberry pi connected by WiFi by another raspberry pi by a python script? I need to Connect\disconect some electric loads of my house switchboard, controled by a script runnig in a raspberry PI in my garage, this one manage the solar system like the charge of the baterries. Try to use a remote controle AC switch but is to far and ins't reayable.

My pigpio Python module lets you control many networked Pis from one Python script.

The controlling script can be running on Windows, Mac, Linux, or a Raspberry Pi, i.e. anything which can run Python.

The Pis to be controlled each require the pigpio daemon to be running.


You can use the SocketServer module to create a server on your pi which will make the GPIO actions. Then you can connect with your second pi as a client to that server an send your commands.

Basic exmaple from the docs:


import SocketServer

class MyTCPHandler(SocketServer.BaseRequestHandler):
    The RequestHandler class for our server.

    It is instantiated once per connection to the server, and must
    override the handle() method to implement communication to the

    def handle(self):
        # self.request is the TCP socket connected to the client
        self.data = self.request.recv(1024).strip()
        print "{} wrote:".format(self.client_address[0])
        print self.data

    def gpio_action(self):
        # do your gpio here

if __name__ == "__main__":
    HOST, PORT = "", 9999

    # Create the server, binding on port 9999
    server = SocketServer.TCPServer((HOST, PORT), MyTCPHandler)

    # Activate the server; this will keep running until you
    # interrupt the program with Ctrl-C


import socket
import sys

HOST, PORT = "<ip-to-server>", 9999
data = " ".join(sys.argv[1:])

# Create a socket (SOCK_STREAM means a TCP socket)
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

    # Connect to server and send data
    sock.connect((HOST, PORT))
    sock.sendall(data + "\n")


print "Sent:     {}".format(data)
