HUE bulbs with brightness of 1 shown as off


I am rather new to openHAB. Up to now, I use following bindings: avmfritz, hue, nuki, bosesoundtouch, and nest.

In principle, the hue binding works as expected. I am able to switch bulbs on, off, change colors, etc.

But when bulbs have a brightness of 1 (or 0) (the night mode), they are shown as off.

When I switch on one bulb via the official Hue App (Android), or Hue Essentials (Android) and the brightness is 1, nothing shows up in the logs. When switching on and off with a higher brightness, everything works as expected.

I am not sure if it is a bug or a feature :slight_smile:

Can someone confirm this behavior? Or tell me what to do?

Changing the brightness from 1 to 50 (or so)

2018-11-12 21:15:48.220 [vent.ItemStateChangedEvent] - Flur_Decke_Toggle changed from OFF to ON

Changing back to 1

2018-11-12 21:16:45.419 [vent.ItemStateChangedEvent] - Flur_Decke_Toggle changed from ON to OFF

The example item:

Switch Flur_Decke_Toggle “on/off” (Licht_Alle_Toggle) { channel=“hue:0100:xx:2:brightness” }

I have seen this before I won’t cal it a big but a know issue. Search the forums you should find it.
