There was a thread on this two years ago which pointed out that US Z-Wave devices can't be used in the US, however the 2019 GURL for SRDs has been updated to AFAICT allow European Z-Wave:

In the band 868 – 870 MHz, the maximum power is −27 dBW (2 mW) e.i.r.p. and the maximum permitted duty cycle is 1%, except in the band 869.20 – 869.25 MHz, where the maximum power is −20 dBW (10 mW) e.i.r.p. and the maximum permitted duty cycle is 0.1%.

That happens to match the European Z-Wave, 868 MHz and 1% duty cycle, which would mean that it's possible to use European Z-Wave gear in NZ even if the official frequency allocated for it is the weirdo 921 MHz. I'll email the RSM folks tomorrow to check, just wondering if anyone here knows more about this...

Hope so, that would open up a few more possibilities for equip buying/operating

Absolutely, it seems like 90% of the gear out there doesn't, and never will, do the official NZ frequencies. Let's see what RSM comes back with.

PLEEEEEEEEEEEEEEEEEEEEAAASE be true....would love to get my hands on some UK Zwave TRV valves. That sort of thing doesn't exist over here.

It may not be the case, looks like the max. power level in the GURL text is much lower than the one used in Europe, so even if technically it might be OK in practice it probably won't be. Will wait and see what the RSM folks say.

Would certainly be a game-changer!

I've asked companies before what it would take for a AU/NZ freqency device. And had been told 100,000 units by one.

Really. The Z-Wave chip can do the AU/NZ frequency out of the box so the hardware should be identical world-wide apart from a simple change in programming the frequency synthesizer. I'm guessing the problem could be certification.

I don't think it's that, you just register as an equipment supplier with RSM to be allowed to use the RCM compliance mark AFAIK. The issue will be that a vendor doesn't want to muck around with that for a couple of dozen or hundred items sold. Which is why Z-Wave practically doesn't exist in NZ, no-one's going to jump through hoops to get the OK for a frequency for which the market consists of NZ, El Salvador, and Peru.

That's not entirely true. All these countries share the same Z-Wave frequency (919.8 MHz, 921.4 MHz) Australia being the biggest market.

Australia
Brazil
Chile
Dominican Republic
El Salvador
Indonesia
Malaysia
New Zealand
Paraguay
Peru
Uruguay
Venezuela
Vietnam

I have bought quite a lot of Z-Wave gear from Oz over the past few years as it's just cheaper over there.

I have some Zwave stuff on NZ frequencies using a Vera Edge Controller.

Would I be able to add any UK Zwave stuff? Need another controller?

My first ever AM radio network connection was with a 1MHz AM crystal(OA91) radio receiver.

To use a zwave device operating at a specific frequency you'd need a controller supporting that frequency so I'd expect yes - you'll need a new UK controller.

Be prepared to expect someone at the door if/when you operate a non NZ approved radio device.

@neb is waiting to hear from RSM to see if there is a technical possibilty of using UK/European Zwave stuff here.

Fingers / toes crossed we hear the good news that we can. Although you'd still need a different controller. Atleast for me, I use Hubitat and had to specify the AUS/NZ radio when placing the order.

Ah, OK. I'd seen a much shorter list, possibly older or incomplete.

Just got a reply from RSM, in their reply they quoted the GURL back at me verbatim which means I now know exactly zero more than I knew before I asked them.

Now trying to figure out how to phrase a second question about whether European Z-Wave is OK in NZ in a manner in which they can't sidestep answering it...
