When we released ProfiLux 4, write access in myGHL had been disabled,
in order to have a look with all the devices connected and how they react.

After finishing our tests, we enabled it now, so you can control it by storing
settings made, as you can on ProfiLux 3, Mitras LX7 and Doser 2, already.

Do not make too much changes at once and review the settings you made.
Even after intensive testing, it's not possible to guarantee, that all is free of bugs at this time.
