And one for the archives. As usual HW answered and was really helpful
and responsive. The problem with not being able to set O2
values below 21 was a old bug, and me not on the latest stable firmware.
The bug was fixed in stable 1.60

The not being able to set 100% bug is now found and a fix will be
released in a future firmware.

Thanks HW!
