Firstly I am not doing this myself - I know my limits and am confused by what I have read. But I want to ensure I order the right Shelly for my scenario.

I think my light switch is without a Neutral so I may require the 1L model.

At the light switch I have the following:

Red cable to Common
White cable to 1
Blue cable to Loop

In case it matters this switch is the last switch in a series of 4.

Do I need the Shelly 1 or the 1L?

Also would the sparky be wiring this at the light switch or is it done in the ceiling presumably where the Neutral wire is.

Thanks

A Shelly 1L can be used with either a neutral connection or not, the 1 requires a neutral to work. If you get the 1L and give it to your sparky, they will be able to make it work either way.

You should talk to a sparky first.

Those shellys are not certified(no SDOC, I think there are sources for the 2.5 model that come with an SDOC) for use in NZ, your sparky may decline to install them for this reason.

They will also be able to answer the question about the neutral.

Shelly 1L Cert of Conformity

Shelly 1 Cert of Suitability

These are the documents that an importer would use to create a SDoC from, required if you are importing for on-sale. As the OP isn't intending on supplying to others, the certs above are sufficient for a sparky to install, as plenty of people in this thread can attest to.

Technically if you have 'supplied' the item it makes you the 'supplier' in Supplier Declaration of Conformity. That being said the certificates provided by Shelly are sufficient to create your own SDoC. There are also local suppliers who will do an SDoC if you buy from them.

The blue in the loop could be a neutral, but as stated above the 1L would be the better option as it can work with or without a neutral. The Shelly 1 is better for if you want to do low voltage 12V etc. The other option that doesn't require a neutral is the Shelly Dimmer 2.
