For a sparky you had me concerned for a minute. 240V AC is LV.
Then I realised you meant connect the voltage free GPO switch with the 3V sonoff GPIO signal. Not 240V GPO connections.
HAHA, yeah I just had to trace back through this thread to find out what I was talking about when I first suggested connecting to the GPIO since it was so long ago. The post I had replied to was talking about light switches, which once you disconnect the 240V wires from and connect those to the Sonoff, then as you say they are voltage free. Once this is done, the switch can be used to control the 3V to the GPIO input. This is the same philosophy that is used by Z-Wave light switches and dimmers (they provide their own ELV to run through the light switch mech.
according to this link there are more certified devices. (including ones with exposed GPIOs)
Does this cover stuff from overseas? I cant believe itead make different ones just for these guys to import? How could anyone tell you used the imported version? (aside from a sticker which would bake off in the roof anyway)

so… if this:
https://www.iot-store.com.au/products/sonoff-th16-temperature-and-humidity-monitoring-wifi-smart-switch
Is CE compliant
according to this:
https://archive.industry.gov.au/industry/IndustryInitiatives/TradePolicies/TechnicalBarrierstoTrade/Pages/EuropeanCommunity-AustraliaMutualRecognitionAgreementFAQ.aspx
We can use it legally in aus? assuming it is ‘low voltage electrical equipment’…
If that’s the input, its not low voltage
- Input voltage: 90~ 250V AC
Great news. Connecting that to a GPO switch is not illegal.
According to the people who had this certified, no it does not. They claim to have had modifications done to comply in Aus. I’ve bought a few but have not looked close enough to verify what has been changed. It could be as simple as applying the RCM (regulatory compliance mark). I don’t know.
Makes no difference in Aus. Needs the RCM and approval.

Low voltage in aus is below 1000v as per sparky Dan earlier (i did not know this).

According to that link CE covers low voltage electrical…

OK i get it, it makes it easier to get compliance here. If i am reading correctly.

You are referring to transmission lines (in Europe if I am not mistaken “low voltage” is below 6000V)
For end-users low voltage is below 12V. I am sure you do not want to put your fingers on a “low voltage” 1000V line
You sure that’s not extra low voltage?
The ones from China are CE certified which is acceptable for Australia.
No, it isn’t. Look at the link Cam posted: https://www.acma.gov.au/Industry/Suppliers/Product-supply-and-compliance/Supplier-resources/products-labelled-with-overseas-markings
I’ve never heard Klago’s definition. The ones SparkyDave posted are correct. AS/NZS3000:2010 clause 1.5.7(a)
I beg to differ, you need to read the document again I believe.
European Community-Australia Mutual Recognition Agreement: Frequently Asked Questions
- What is the EC-MRA? The EC-Australia Mutual Recognition Agreement (EC-MRA) is a Treaty-status Agreement between the Australian Government and the governments of the European Community. It came into force on 1 January 1999.
Then under item 5
CE represents “Conformité Européenne”. CE Marking indicates that a product may be legally sold in all Member States of the European Economic Area. Each Member State must accept CE Marked products without requiring any further testing or approval in relation to requirements covered by European regulations.
Now read the ACMA link I posted:
Products that are labelled with overseas markings (for example, ‘CE’ mark or FCC approval) cannot automatically be lawfully supplied in Australia.
The mutual agreement allows for CE certified products to be labelled with the RCM by the exporter. Without the RCM the product cannot be sold in Australia. The products direct from China do not have the RCM. They cannot be sold legally in Australia.
One thing to bear in mind…these products are not purchased in Australia.
Also, I don’t see any mention of the treaty I quoted becoming null and void on the link you posted?
IMHO, CE compliant products are compliant with Australian Standards.
But then again, each to their own (opinion).
Cheers!
The ACMA regulates compliance marking. Importers (or domestic manufacturers) are usually responsible for testing and compliance marking.
The mutual agreement only allows for regulatory compliance marking by the exporter Instead of the importer.
The product still has to have an RCM to be used in Australia.
The Chinese product does not have an RCM therefore it is not legally allowed to be used in Australia. CE is not the RCM. It means zero in Australia.
The one purchased from the Australian supplier does have an RCM. It can legally be used in Australia.
Yes they are very likely identical products and Yes you’d be had pressed to read an RCM on a device that caused your house to burn down but that’s not the point. The thread is about Australian Certified Hardware. For this it must have an RCM.

Also bear in mind that the CE marking may not represent EU conformity. Products from china also use a similar CE mark (china export). https://ce-check.eu/ce-marking-topics/the-ce-mark-of-a-product-real-or-fake/

Indeed sonoff are not, as general rule, ce certified, as in european certified.
The certificate they display on their website are for wifi compliance, not electrical safety.
