Looks cool! Do you have experience with capacities switches? I did not play much with them. afraid to use close to AC interference though...
You need to use a capacitive IC with active shielding, basically you have an extra electrode around your touch electrode and the touch IC will compare capacitive change of the touch electrode with capacitive change from the shield electrode. If the change is due to electrical interference then both electrodes will be changed in a similar way and the IC will not trigger.
I like those relays. Is that 3 different switched outputs? One thing I always liked about european wall switches is that they give you more room for components. I would like to use a similar type of relay for my in-wall switches, but with the way US single gang wall boxes are, there is a pretty narrow space constraint. I might be able to fit it if I did away with the thermal fuse, but I don't want to give up tat bit of added safety just for that.
I'm wondering what the minimum input voltage is. The description only says max. 6.5V input voltage from the battery, but does not say what the minimum is. Both the nrf24l01+ as well as the atmega328P work with 3.3V, so if I use three AA batteries, that should be fine, right? I suppose using two AA batteries is not enough?
