I just bought a (RaZberry2 ZMEKRAZ2 EU) and when I try to change region to EU in Z-way advance I just have option KR or JP, all other is grayed out.

I have run the sh script (sh changezwf.sh /dev/ttyAMA0 EU) and juppii (Switch to European Frequency (848.4 ... 869 MHz)) BUT!!!
but but after a restart, RaZberry is back to JP or KR.

Do I need a firmware update to change or am I stuck with some KR / JP region

and what is up with this token circus to access FW update, I could use one

Thanks for reading my post, hope you have a solution 4 me

Z-Way is not changing the frequency itself. So may be you executed that command or pressed the button accidentelly.

Also be noted that KR and EU uses same filters, so the range will be very small.

Hey PoltuS

I need some help, is there a guide on how to change the region from KR to EU

and what does the physic bottom do on the RaZberry,

Thanks

The button goes to RPi pins. You can catch it using standard pins system in Raspbian. Nothing is done on the Z-Wave side.

As for frequency change, do IP:8083/JS/Run/zway.ZMEFreqChange(8)
