Hello, I'm using the UZB Stick with Z-Way server. Under http://localhost:8083/expert/#/uzb there are several possibilities to upgrade the firmware.

• 2014-12-01 5.2 Update firmware from 05.02 to 05.03
• 2015-11-07 5.2 Update firmware from 05.02 (EU/US/ANZ/RU/IL/MY/IN) to 05.04 (EU/US/ANZ/RU/IL/MY/IN)
• 2015-11-11 5.2 Update bootloader for 05.02 to 34A9

Is it save to to do these updates? Which sequence of updating is recommended?

Don't upgrade, before they they have a proper disaster recovery procedure in place! When this will happen? I don't know.

Don't be scarry

First upgrade bootloader. Then upgrade to 5.04. Make sure to preserve log of the process just in case.

If you had license key, make sure to reboot the dongle (Reset Chip in Expert UI and restart Z-Wave binding [or full Z-Way]) before running your system again.

Yes Polto's, but if UI continue to say:
2015-11-11 5.4 Update bootloader for 05.04 to 34A9 Upgrade bootloader
what it means? wath we must do for remedy?

I hope they do tackle that with Issue #171 as well.
