ok so here is a code snippit you can paste into a python script and run.
You need to change the IP_ADDRESS variable to have the ip address of the relay board
If you have your device set up to use a password then you will need to change PASSWORD to be the password you are using
once you run the script it should display a new application window and there will be buttons for each of the eight relays. You can toggle the buttons on and off and it will turn a relay on and off.. what i am interested in is the data that gets spit out into the log when you do this. you will need to copy that data and paste it here for me to check out. we need to know what the data is that is being returned from the get command
Code: Select all
IP_ADDRESS = '192.168.1.1'
