Indigo Domotics

I know it is probably a stupid question, but.....

I have a UK zwave connected to my Indigo.

But looking at all the interesting battery/usb powered zwave on Amazon.com - couldn’t I purchase a US frequency zwave transmitter/receiver and add it to my Indigo so I could use all those good things?

I am aware of the frequency difference - and potential naughtiness of using a US one in the UK.

Is it possible?

No, Indigo only supports 1 Z-Wave network (and you can't mix frequencies in a single network).

Well, unless you want to use a Vera and the bridge plugin.

What’s the legality of running with US frequencies in the UK?

I don't know but suspect that you are not allowed to sell something running on an unapproved frequency.

My view is that any effect I have on radio waves by running a US frequency zwave is extremely local.

Is a radius around my house.

So, if I buy a US Vera edge and put a bridge in I could potentially run a cheaper, and more flexible range of zwave products.

I'm just trying to find out if the Veras are universal and can change frequency or locked to each region.

Just note: the vera bridge plugin only supports on/off/dim devices, thermostats, and locks. It is, however, open source, so anyone who wants to expand that list is certainly welcome to fork it, make the mods and issue a pull request and I'll merge and create a new release.

I agree that it's likely illegal to use US Z-Wave in the UK because of the frequency - it' may conflict with other things on the same frequency or it may be in a band thats reserved for something else. In the US there's an agency that monitors such things, though I suspect that's really just WRT approving a device for sale.

WRT?

Also looking around it’d seem 908Mhz is reserved in the U.K. for mobile use.

Ahh! Gotcha. I DuckDuckGoed it but there were many different uses of it

880-915MHz–Ofcom(fortheFixedand Mobile services)
890-915 MHz – MoD (for the Radiolocation service)

In the UK
So unless you have MoD activities in your house, unlikely to clash.

I’ll keep digging.

Either that or have some army chaps knock down his door to confiscate the equipment..

If the zwave is putting out that much power I’m going for world domination!!!!

Guys.

As well as home automation, I also run 28 sets of Radio Microphones under license from Ofcom, so I'm aware of radio licensing.

A year or so back there was a large televised public event - I can't remember which - but on the morning of the event there was interference on the radio mics.

The technicians called Ofcom who turned up with radio detection equipment - and pinpointed a chap who was using unlicensed radio mics in licensed frequencies a significant distance away, in his bedroom.

The guys equipment was confiscated and he was fined £2,000.

Radio licensing exists for a reason, and licensed users like myself are harmed by those people who think they're above it.

Please don't even consider using US frequency equipment in the U.K. It's not fair and it's not worth it.

I have to agree. You never know what kind of issues you may inadvertently be causing. It's just not worth it.

Second... errr third or fourth?, that... especially on or near radiolocaton services, it only takes a tiny signal on a beat frequency to make somebody think they are somewhere they aren't , and if you call down a commercial airliner making an automated approach to a nearby airport in bad weather, a fine will be the LEAST of your problems.

I hear you.

I didn't understand the range/power of the zwave transmitter.

Does open up ideas that I did not think were possible though.

With that sort of range I could actually ally set up automated processes for my whole street and offer it as a managed home automation service.

If it can effect commercial airplane navigation I could easily run a smal town with a single Vera box.

I hadn't tested it, I just assumed it had a very limited range, i.e. House, not street, city grade.

Should I be worried about the radiation coming from my USB zwave transmitter?

But seriously, you are right, all the same I had not anticipated zwave signals having such a reach.
