Great job. Are they are solid state relays though? Must open one up. I'll do that now.
No, they're mechanical which is where the clicking sound comes from.
Couple of suggestions. First is cables exiting the box aren't protected from being pulled. A cheapo way is to put a few cable ties on them on the inside. But ideally aim for IP45 and put them out through gland nuts, which only cost a few quid and will protect somewhat against water getting in.
Other suggestion is the live and neutral don't need to be wired into a strip like that, the same can be achieved by wiring them into the STC-1000 (daisy chain the live, put all the neutrals into the neutral terminal on the STC. Won't save much money but handy when you don't have a enough strip connectors.
