Electrical questions
Looking to make a few things in the house ‘smart’ either with a Shelly relay or with smart switches.
Looking at the back of both a fused spur (heated towel rail) and light switch, it looks like both have neutral returns.
For the light switch - why would there be three? Assume I should just connect all of them to the smart switch neutral?
For the relay, which of these two neutral in the fused spur does what? Any ideas?
