This is why my plan was to make a couple of small pcb's that are isolated and fused so if something happens, it will be isolated. I That is also why i want it to keep everything in the 5 volt area and only use the heating and pump on the 230v. The rest will be LED's and electronics runing on 5 volt.
I will be searching on the online electronic suppliers you mentioned.
The online espresso parts shops sell the SSR's at around 50$ and i need 3 of them.
Thanks for the info and heads up.
