I just started to work with openHAB, so forgive me if my questions are completely stupid…
A brief list of what I did so far:
installed OH2 as a QPKG on an QNAP NAS.
attached a USB stick cc2531 to the NAS.
loaded the appropriate kernel module
added the Zigbee binding
added CC2531EMK Coordinator Thing
coupled an INNR bulb RS 228 T (ZigBee Device)
added two items of type “Dimmer” to the channels “Color Temperature” and “Level Control”
so far, so good. When coupled, I was able to control the bulb using openHAB Control page, using both channels.
Some time later, I could no longer Control the bulb. Color temperature and Level stay constant.
Both things still show up as “online” in Paper UI.
Also, coupling further bulbs does not work.
btw: I also noticed that when changing either channel via the openHAB app, the web interface would not reflect the change - only after another change.
initial value CT 100, Level 100.
Change CT via app to 60.
webinterface: no Change, still reading CT 100, Level 100.
Change Level via app to 50.
webinterface changes, now reading CT 60, Level 100.
Change CT via app to 40.
webinterface changes, now reading CT 60, Level 50
and so on.
