What amperage rating are the relays, or is this something I can add myself? That sounds awesome, and better than the pre made, as long as it can handle the power of all that equipment loaded. I'm guessing you will also have to sort of protection built into it, breaker/s or fuse/s. That is the type of controller I'd really be interested in, I was thinking of buying a PLC and let one of out programmers do the logic for me, I'm sure I could twist their hands into this neat project, I'd also wanted to add an HMI, it would be so nice to have direct access, I could do the graphics myself. I really like what I've seen so far & can't wait to see the complete package, The Internet stuff is cool but I'm not as concerned with that as much and the control system itself, remote access later can be dealt with but glad your planning and leaving room for it also.
