This library allows you to control Solight DY08 sockets from Raspberry Pi.
Connect cheap 433 MHz transmitter to any GPIO pin (e.g. 17)
sudo apt-get install pigpio-python
sudo pigpiod
import time
import pigpio
from dy08 import DY08
pi = pigpio.pi()
dy08 = DY08(pi, 17)
while True:
dy08.send(42, 1)
time.sleep(1)
dy08.send(42, 0)
time.sleep(1)
...
Profit! :D
