Tellstick duo firmware upgrade with telldus center 2.1.2

[olavjunior]

Just downloaded the 2.1.2 but I'm stuck with firmware 4 on my duo.

How do I upgrade this? It's supposed to be possible in telldus center, but after hitting the up-arrow in "configure" the flasher started and flashed, but it still says I'm on firmware version 4.

Do I have to download the firmware and put it somewhere for telldus center to be aware of it?

EDIT: After a reboot I'm seeing firmware version 12

BUT I don't get any temperature page on my telldusCenter, even though I have two sensors that's working perfectly fine in SwitchKing.

Any ideas why I don't get the temperature page?
