I have a Dimmer 2 driving in total 5 led bulbs at once. I came from a fibaro hc2 and I never had problems with dimming. Currently the lowest brightness is super bright…I can’t dim this down as needed by night for example. Can anybody help?

A short search on this forum and you could have found the answer:

> Both the calibrated numbers (1 and 99) are wrong. The “Force calibration” value is also wrong. It should say readout. The device itself has finished calibration. This is true of all my dimmers. This was not the case on 1.5.
