I have a raspberry pi, and I a significant number of relays in my house that I want to monitor. How can I use the Raspberry pi to monitor these relays, I do know a bit of electronic knowledge and good amount of python code.
There are 64 relays I need to check, and need it to check if one goes out, which one had gone out. All of the relays are fairly close together enough that could wire them directly to the pi.
Any ideas on how I could go about this?
