Sigma UZB and frequency question

Post by jambel » 06 May 2015 21:18

Hi,

I have a US Sigma UZB controller. I run the script that change the frequency (http://www.z-wave.me/index.php?id=28) to convert it to EU.

Result:
$ sudo bash '/home/john/Desktop/changezwf.sh' /dev/ACM0 EU
Switch to European Frequency (848.4 ... 869 MHz)

But how can I check that it's changed, or this script does not support the Sigma UZB?

Thanks.

US and EU z-wave trancievers use different RF hardware. So, A.F.A.I.K you cannot change from US->EU (for example EU and RU have same hardware so you can switch frequency)
Also commands to switch frequency are manufacture specific.

Note that this script is Z-Wave.Me specific. It will not work with Sigma UZB.

Also as stated above, even after switching from US to EU the range will be shortened due to SAW filter difference.
