I've been using Node Red for several years.? It's been fantastic to allow me to do various automation functions around the house without knowing how to code.
I have some extra input/output PC boards I designed to interface to a raspberry pi.? The board has 4 opto isolated inputs and connects to the generic cheap 8 relay boards found all over the Internet.
These are bare boards and you will need to supply your own parts. I have a small number of 26 pin headers and ribbon cables left.
I only want to cover postage and a couple of bucks for the 26 pin headers and ribbon cables. The boards are no charge.
If your interested, I can supply a .png of the schematic.? The picture shown here is a populated board I will be keeping but gives you an idea of what the board is.
