I have some questions regarding Zigbee and IKEA Tradfri light bulbs. I have previously been using the IKEA Tradfri Gateway and Home Assistant as a bridge between that and KNX. Have worked flawlessly, but I have not been happy with the amount of separate places to have config. Bought a LM5p2-KCDZ to replace both that and other gateways 
But some problems/questions have arised:
1: When I set a certain brightness directly via KNX, it jumps back to the previous brightness untill it has reached the new one. Say I have a bulb with brightness 80%. If I enter 50%, it jumps straight back to 80% while the bulb transitions to 50% - then it shows to 50%. This is not KNX usually works..?
2: I can't really seem to find an explanation to the "Internal Level status" and "Calculated Level status" on the Zigbee configuration… As far as I can see they both work fine as Brightness feedback (except issue 1)
3: When I change the colour using KNX RGB, brightness seems to always change to 100%. Before getting the LM5 I used an IKEA Tradfri Gateway With Home Assistant as the Gateway between that and KNX. This did not happen there…
4: I don't understand why there can't be an RGB Value Status on the Zigbee Configuration, since there is both on/off status and internal level status? I'm using an event script on the RGB Value GA, to update a status GA - but is that the proper way? I guess it should be ok, since the only way to manipulate the RGB of the bulb is through the RGB value GA? But in general, I guess I should poll the value via Zigbee, not just send the value GA to a status GA? Or..?
I did not have any of these problems with the Tradfri Gateway and HomeAssistant combo, but I like LM so much better! Hopefully there are fixes/workarounds for these issues...
