So this popped up for me in the other day...

https://www.cnet.com/news/this-teeny-tiny-smart-switch-fits-inside-your-walls/

They talk about a dimmer, but Shelly's website had absolutely nothing about it, and it seemed this is the only article that specifically says it exists.

But now today I go and take another look at Shelly's website and it's there available for pre-order!!! Finally a Wi-Fi connected dimmer, with MQTT support - And it's around $35 NZD!!

Let's be honest, probably never. I'd be interested to find out what's required to make it happen though. I imagine a test batch of many thousand is required though? Compared with the Z-Wave options, could still work out quite well cost wise. Meh, will wait for my lot to arrive and see how well they work.

I'm awaiting the article... "Insurance company denies payout for house burning down as it had a IoT device installed"

Ummm I would be VERY careful bringing in the product that does not comply with the RSM rules and posting it here where RSM monitor.

They need to comply with all the rules posted https://www.rsm.govt.nz/business-individuals/supplier-compliance/

If this product causes interference with equipment and RSM to work out its this that caused then look out there will be ALOT of fines coming to you.

It annoys me that so many people don't care about RSM rules for EMC and Interference and yet as a supplier, we have to jump though major hoops to get the legit product to market.

Was just about to say exactly the same thing lol. I'll stick with my Fibaro Z-Wave switches and dimmers, even though they are triple the price, but also triple the functionality, low-energy radio, fully meshed (the more devices the better - opposite of wifi), more secure etc. I get MQTT functionality out of them once they hit my home automation, giving even better flexibility (like sending that info to my MagicMirror etc)

What about the Shelly isn't going to comply with RSM?! It's a standard Wi-Fi client.

Not all Wifi bands and devices are approved for NZ, i know a number of devices you cant get in NZ that are "Standard Wifi"

Also need to be able to prove that they comply with the EMC and not all CE and RoHS compliant standards are approved between NZ and the EU.

It's more so their power compliance than wifi compliance I'd be concerned about

However based on the fact these are better build quality than sonoff, and plenty of people here run sonoff... well, your risk.

Be careful with MQTT persistence though, especially if flashing with tasmota. I had a sonoff relay flick on/off constantly til it started smoking and fried itself

Watching with interest to supplement a couple of shelly 2.0 - price point hard to beat.

Oh there's always a risk, but Shelly seem reputable. The units have thermal protection and power monitoring. More effort has gone in to them than the likes of Sonoff - which as you say plenty of people run without burning their house down.

And I'm pretty sure the native app supports MQTT itself now so no need to flash with Tasmota for normal use.

If it's CE stamped (which it will be) and certified for use in the EU the chances of it burning your house down seem pretty minimal to me.

But what do I know? I'm not a sparky.

There was a study of the fire risk of TRS & VIR wiring in NZ. Even though faulty wiring does cause some fires IIRC the overwhelming electrical cause of fires was heating devices. If you want to beat the fire risk drum the bogeyman is portable heaters.
