Thanks for this.

I'm running a US ST hub at home, buy currently only have Zigbee devices (wemo bulbs & ST motion / temp sensors)

I'll have to go and turn off the z-wave transmitter.

How long have you been running ST? Is it easy to turn off Z Wave. I got one, obviously before I read this sticky and haven't even opened the box as I am not sure if I should? Anyone else here running ST?

Not long, had it sitting in a cupboard for about 8 months, but the wife went away for a couple of weeks so I played with some projects.

I went to the website to disable z-wave

https://graph-ap02-apnortheast2.api.smartthings.com/

On the next page is a disable z-wave link, and after that the z-wave section on hub page will show disabled.

Login with ST account, and click on my hubs. Then View Utilities near the bottom of the list.

Thanks. So, is it absolutely safe to use it after disabling Z-Wave? There is no way it will enable itself? I don't want to get in trouble for something so stupid and don't wanna keep thinking about it re enabling Z-wave itself.

No. As per the OP it is a software switch on a radio that doesn't meet NZ requirements and may still broadcast and thus still in breach with RSM. If you've got a smartthings hub then you should cease use of it.

That is very interesting to hear that the RSM actually tracked someone down and knocked on their door. I always assumed it was a bit of a hollow threat. It must mean there was noticeable interference with something they monitor.

We had some people gibber-jabbering in a foreign language on our work RT frequency for weeks on end. RSM did their best to track them down and eventually issued us with a new frequency to resolve the problem.

i find it very interesting that they could not locating the source of gibber-jabbering, but were able to locate what i'd expect is far less powerful zwave equipment in a house!

I imagine that it is harder to direction find on an illegal transmission when it is intermittently transmitting simultaneous to legit transmissions. Also RT's move around. Possibly once we vacated the old frequency the job of tracking the offender down was made easier as they would have been the only transmissions on the frequency. Also, your zwave will transmit near continuously, where as voice is intermittent and may be quiet when the direction finding gear is all set up.

Additionally cell site cell's in urban areas are realatively small compared to the range of a 25watt RT. A rouge RT could be anywhere in the city. If an imported zwave is interfering with a cell site, then Vodafone is likely to be able to give RSM a relatively small area/valley/suburb in which to start hunting. When direction finding there would only be 2 sources of signal (legit and illegal) and they both stay still, unlike RT's which are mobile and there can be dozens of units transmitting one after the other. The cell companies pay millions of $$ for their frequencies, where as an RT channel costs approx. $300 per year, so the RSM will no doubt put more resources into the more valuable clients interference.

I found the https://www.mysensors.org/ project recently.
It's an open source Arduino project for creating your own sensors, repeaters and gateway that looks like a fun DIY project.

One of their supported transceivers is RFM69HW which comes in 315,433,868 and 915MHz variants.

It has programmable power out: -18 to +20 dBm in 1dB steps.

I'm I correct in thinking you can't use the 915MHz variant because it would exceed the condition 23 limit in the GURL (Maximum –79 dBW (–49 dBm) e.i.r.p. within 800 – 915 MHz)?

But you could use 433MHz if you can limit the power to –16.0 dBW (+14 dBm)? What sort or range would that allow?

Is there a way to open the ST and disable the Z-Wave by disconnecting the antenna if there is one or doing something else on the board?

I am thinking of buying the Samsung Connect Home from Amazon as I want a device to extend my WiFi coverage and I want to use the SmartThings functionality. I udnerstand Z-Wave can be turned off as an option. Anyone here use the Samsung Connect Home kit in NZ?

Please read above. As it contains a non compliant transmitter it can't be used in NZ.

So what platform (system) would you recommend selecting at this point and time? Zigbee, waiting for Z-Wave of going Wifi only devices?
