Sonoff Zigbee Bridge and Ikea Tradfri - Pairing issues

Hello, I have three Ikea Tradfri Lights with Dimmers of this type and I have a Sonoff Zigbee Bridge flashed with Tasmota.
I am trying to add the three bulbs to Home Assistant so that I can control them either via HA or via Dimmer.
Somehow I always make something wrong in the resetting and pairing because I can always add the bulbs and the Dimmers (seen as On/Off Switch) to HA but then all the three dimmers control all the three light bulbs at the same time (I can only turn each one on or off via HA, but when i push the dimmer button i turns off all the three bulbs).
What am I doing wrong? Is there a right way to do this?
Thank you in advance,
Dario

I’m testing a bit myself with the same equipment.
It seems like you managed to pair the switch with both the bulb and the bridge.
Try to reset all the devices and only have power to one device when pairing it with the bridge.

I turned out that the bulbs were all getting inside the same group (0), so i had to remove the bulbs from the group to use them separately…
