I could be interested in some. I was trying to figure out what a Shelly 1s is but I have figured out they are Shelly 1's... ;-)

Hah yeah. It's a Shelly Special. I'll PM you tonight.

SirHumphreyAppleby:

 

The remotes on these usually switch mains power. There are even some versions out there with XLR plugs carrying mains power to the remotes. Don't plug the wrong thing in there!

Bingo! Lucky in this case not a XLR. Have bought a Shelly 1.

Thanks all for your suggestions! Looking forward to trying it out.

yep, have been having the same issue. Its been discussed elsewhere, shellys being quiet about it. 

alsta: Just an update re the random single flash I’m seeing with my Dimmer 2s

Turns out it isn’t a ripple signal as our neighbourhood is on a digital not analogue ripple - a filter that was tested on a circuit didn’t do anything to remove the single flashes and actually
caused flickering to occur at the ripple time

So….I’m going to try getting a dimmer load balancer put in which Shelly recommended
Still keen to hear of anyone else has seen this issue?

I have a similar issue here.  It doesn't happen enough for me to get annoyed and I notice it more when the lights are at 100%.  

However, knowing that it is an issue annoys me more, and so would like to get a resolution.

Any luck on that PM'd recommendation?

No - sparky was adamant it wouldn't help....

So, I've contacted Shelly again via a Facebook PM. Had to set up an account just to interact. There do seem to be a few folks agitating about it on the Facebook forum so hopefully they'll be a resolution at some point with a firmware update.

jol: Any recommendations of electricians in the Hutt/Wellington area who are known to install self-imported Shellys?

After my usual electrician refused to install (they are still sitting on my desk in front of me), I asked Worksafe to comment on the installation of certified devices that aren't accompanied by an SDoC (as would be the case if you import yourself). In short, my interpretation is that if the product comes from legitimate sources and has the correct certification, there is no reason not to install the product.

 

Hi David,

 

“Re: place of SDoC and COC in the transfer of responsibility for safety of electrical equipment an Electrician is installing, to the original supplier”

 

Electricity (Safety) Regulations 2010, Regulation 83(3A) explicitly details that - for the purpose of issuing a Certificate of Compliance(CoC) for PEW or for a issuing an Electrical safety Certificate (ESC) the person(EW) issuing the certificate is entitled (*if acting in good faith) to rely upon the veracity of any supporting supplier declaration of conformity (SDoC) relating to the articles used in or incorporated into the installation.

 

This regulation explicitly applies only to declared medium risk articles and SDoC, as defined in ESR Regulation 4. An SDoC voluntarily produced for a product that is not a declared medium risk article, is not recognised as an SDoC under this Regulation, so does not have the same level of recognition. However any reasonable documentation can be used to support the completion of an CoC or ESC, if it was used by the EW to determine an articles safety. The difference being that the Regulation specifically recognises an SDoC as defined for this purpose, whereas any reasonable compliance documentation used as the basis of electrical safety, can be used in mitigation by the EW, if the article subsequently proves to be unsafe.

 

JAS-ANZ Certification including a CoS is directly recognised as a test report by ESR 81(3) (but not as an approval).  JAS-ANZ Certification that the product certified fully complies with the standard it lists, is recognised evidence of electrical safety under ESR 80, but only if the relevant cited safety standard matches that in the certification? JAS-ANZ Certification therefore can be used as evidence of electrical safety to support a CoC , whether or not the article is a declared medium risk articles.

 

(Note:- Although recognised, we have become aware recently of some JAS-ANZ certification issued, that although stating it complies with the AS/NZS standard, in fact only complied with the Australian requirements of the standard and does not include the NZ national variations that apply, this is incorrect. This particular issue is being addressed by Energy Safety with JAS-ANZ currently. )

 

The original supplier in NZ, whether an importer or NZ manufacturer is legally responsible for ensuring that the fitting or appliance supplied in NZ is electrically safe under ESR 80. For declared medium and high risk articles there are also pre-market requirements for supporting compliance documentation, as detailed in ESR 83 and 84. Although an EW shares the responsibility with the supplier for the compliance and safety of any electrical fitting or appliance the EW installs, the proportion of blame and therefore liability of those parties will depend upon the due diligence they each applied, in relation to the fitting or appliance supplied and installed.

 

*Note “if acting in good faith” generally means that there is no reason for the EW to doubt that the article is compliant or safe, from the knowledge and experience that an installing EW is reasonably expected to have.

 

An electrical fitting or appliance even if supplied with what appears to be genuine supporting compliance documentation,  still may not be compliant or safe. The EW is still expected to be duly diligent and not rely purely upon supplied documentation. If there is any reason to suspect that it may not be correct. A simply check of the description (photos if any), brand and model numbers, , all match the product certified. There are also issues with counterfeit products and certification, anything that does not look right, needs to be challenged. However if everything does look correct with both the certification and the product, there is no reason not to install.

 

More caution perhaps needs to applied to product obtained from sources other than the mainstream national Electrical Wholesalers, the experience in have used these Electrical Wholesalers for supplying compliant and safe electrical  fittings or appliances in the past may be considered to be sufficient alone without the need for supporting documentation. Whereas search the internet for cheaper fittings or appliances from companies you do not know from previous experience requires more diligence by you as the EW who will install and certify and relying on such fittings or appliances without reasonable evidence of safety and compliance, would be a risk.

 

Just to reaffirm again an installing EW, if having reasonable concerns regarding the safety of a fitting or appliance, they must not install that product until reasonably satisfied that the fitting or appliance  is both compliant and safe.

 

Hello All,

Just on the Shelly 1 PM topic - I am looking to get automation my AC, Water heater and the Cooktop/hob - but all of this needs higher Amp support (with Cooktop needing 32A). I reached out to Shelly and they said the maximum they support for switching and power monitoring is 16A. However Shelly 3EM and EM can measure power phases with upto 120A, but they cant switch devices.

I am keen to atleast get the relay for the cooktop.. to just cover for the forgetful days. Any recommendation on what products I could look at will be very useful!

TIA

You can use the Shelly, having it switch a second relay that can handle a higher load.

Most AC units offer control via WiFi (HTTP API)/IR or other interfaces that integrate with third party automation software. These provide more control and won't damage the equipment as you could when switching mains power.
