Dear Z-Wave.Me,

I have a ZMEAUZB1 running 05.26 which I would like to downgrade to 3-channel 5.22 firmware for JP/TW/KR.
Do you have a firmware image that can be used to revert back to 5.22 (as there seems not to be any equaling for 5.26).

Also, I only see EU, RU, IN and CN region for my ZMEAUZB1 which is running 05.26 which is kind of odd as it's not a AU variant, not EU.

Best regards,
Jon

If I try to change frequency on my ZMEAUZB1 to ANZ by sending the following hex chars: 01 04 00 f2 04 05, I get hex 15 in return. If I however try EU (01 04 00 f2 00 09), the Z-Wave dongle restarts as expected...
The same for my upgraded us dongle (v05.25), ZMEUUZB1. It only accepts EU frequencies.

Best regards,
Jon

Downgrading from Z-Way 2.3.5 to 2.3.4 solved the frequency issue.

For firmware v05.26, does this firmware now support Korea/Japan/Taiwan or do I still need a downgrade image for 5.22 firmware ?

Seems the upgrade to v05.26 wiped Z-Way license of all three dongles.

If I try the original license key's I get unable to verify. How to recover ?

Hello,

we must reset the License
