Psilan:

I might have a few to sell shortly. I bought much more than I needed in the end.

I just tried to have my Shelly's installed, but the electrician refused. He had the documentation a few days ago, including the Global-Mark certification which can be verified as legitimate, as can their ability to issues such documents in the JAS-ANZ database. He checked with an inspector who also advised against installing the item.

It appears the sticking point is one of responsibility rather than compliance. According to ewrb.govt.nz, the electrical worker can transfer responsibility for safety by citing or attaching the SDoC to the CoC. Does anyone know what the actual regulations or legislation states regarding this? I haven't been able to find the relevant information.

It seems bizarre to me that an electrician can rely on an SDoC, which may be issued under the false assumption that manufacturer-supplied certifications are legitimate, yet a chain of certification that can be verified can't be.

as the importer, I composed an SDOC myself, attaching the Global mark cert.  it did the trick.

I suppose their coming at it from a liability standpoint. From what you have said and whats on ewrb.govt.nz the SDoC resolves the EW of any liability if the device fails. The liability falls on the provider of the SDoC. I wouldn't have thought it would be a huge issue as most EWs will have liability insurance, however I can see how any insurance could have an exclusion.

That's a good idea. Note this is only my opinion, but reading though the SDoC template and the section on them in the Electricity (Safety) Regulations 2010 I can't see any reason why this wouldn't follow the rules. It just means you would be liable if the device failed, not the EW.

It appears at least part of what I was looking for was right under my nose in S83 of the aforementioned regulations.

"S83(3A) For the purposes of issuing a certificate of compliance ... the person issuing the certificate is entitled (if acting in good faith) to rely on the veracity of any supplier declaration of conformity."

So, there we have it. The EW can rely on the SDoC, however, it doesn't mean the EW can't rely on other documentation.

While writing your own SDoC appears to be completely valid, section 83 of the regulations is titled "Supplier declaration of conformity required before sale of declared medium risk articles". No sale ever occurs by a NZ-based importer or manufacturer, so I guess it's up to the lawyers to debate the meaning of supply/supplier within that section to determine if the requirement for a SDoC is even triggered.

If you look at 83 (2) it says  "A declared medium risk article may not be sold, offered for sale, supplied, or offered for supply unless—". Either way its academic as to if one is "triggered", if the EW wants one then its their prerogative. They can refuse to provide service if they want to. It would be interesting to know if this particular EW would accept a SDoC you prepared or are you just going to try to find another EW?

I'm not considering either option at present, just trying to get clarification around the issue as this is something that people will keep running into. I was intending to use these with a driveway beam to control outdoor lights. The same sensor also triggers notifications and a warning light (12V) at night, so having the Shelly installed would fall into the category of nice to have rather than a necessity.

I actually don't want to use them, it's just the most convenient (and theoretically certified) option for a retrofitting scenario. My medium-term plans are for a new build, where I will have the flexibility to get wiring where it needs to be.

The contact points  on the 1PM are too small for fatter gauge wiring, (I wanted my bathroom heaters on it, but the wiring was too big)  but if it did fit, a 10a heater is much more likely to kill them faster.
I don't know the full details (I worked in IT, not Electrical), but for high amp devices you can use a dry contact relay instead, so the Shelly controls a separate switch with the amps running through it, rather than cooking itself directly.
Its something I might get round to doing for the heaters, as I want to leave heaters on to clear the moisture in my small bathroom, until the temp/humidity sensor achieves a satisfactory score.

But basically, if you want it to last 10 years,  don't trust the high load ratings......

The question to ask is the device a medium or high risk declared article. If this is the case then it would require an SDoC. 

An SDoC is required for medium risk declared articles (as under ESR 2010 Reg 83). A list of the different types of equipment that are med or high risk articles can be found on the WorkSafe - Energy Safety website https://www.worksafe.govt.nz/topic-and-industry/electricity/appliances-and-fittings/high-and-medium-risk-products/

An SDoC is created by the person in NZ who is importing the device.

From the current list I believe there does not seem to any category these currently fit into.   

Currently the ESR's do not have a cited standard to automatically show conclusive evidence the fittings comply with Regulation 80 (new and used fittings and appliances to be electrically safe). IE the fittings have been deemed to electrically safe.

Therefore the fittings could be deemed electrically safe if they complied with AS/NZS 3820.

Seems to imply that the dimmer2 has been certified.  But no mention of the dimmer 2 on the global-mark site.

Not sure what it means for NZ, if anything? 

Same for 1L.

It looks like they used SAA instead of Global-mark

That page has approval number SAA-203334-EA

Putting this into the SAA approvals webpage (just 203334)

https://www.saaapprovals.com.au/resources/certified-product-approvals-register/

yields

Approval No. RCM? Model Article Description Expiry Date 203334 Y Shelly Dimmer 2 Smart WIFI Dimmer Switch 2026-01-29

So - looks legitimate.

edit -  hairy1 beat me to it.

Luckily I bought a few of the dimmers with my last order :D.

Anybody know the correct PDL Iconic switch module to purchase?

I currently have a standard switch with rotary dimmer. Wanting to just change to 2 simple press buttons for the Shelly Dimmer.
