Tradfri remote control is behaving inconsistently

I have just added a Conbee to my Raspberry Pi so that I can start automated zigbee devices in HA.

I have installed the deConz add-on and successfully added two Ikea bulbs and the Tradfri remote control through the Phoscon app in HA.

I can control the bulb with the Phoscon app (dimming up/down, changing color temperature and swithing on/off).
I have issues with the Tradfri remote control. I have managed to pair it successfully and I have configured the buttons this way :slight_smile:

First of all the dimming and color control don’t work the same way it worked before when my remote was directly connected to the bulb (without conbee). Before a single press on any of these buttons would trigger an incremental change. Now I have to long press and wait for too long before seeing a change (probably the increments are too small)
And sometimes I don’t see any changes at all, I have to press again.

How can I change the increments and is it “normal” to have inconsistent results, is it a compatibility issue ? I thougth about radio frequency issues, but the all the devices, including the raspberry, are in the same small room.
