Problem with Light Switching

I dont know how to describe my Problem.
so i have made a video: https://youtu.be/fReYl9QrEdo

If i put on a light (tasmota) 2 other tasmota lights putting itself on.
the same if i put them off.
if i put them off via tasmota webinterface, only the one putting off, is off,
the other 2 are still on, but shown off in HA webinterface…

my system is:
Home Assistant OS 6.2
core-2021.8.8
installed on
Intel Nuc - i3-3xxx, 8gb ram, 128gb ssd

the deConz currently running on a raspberry pi, but will move to the nuc,
once i ve found out where the problem is…

Tasmota devices need to be configured with unique client names.

thank you very much.

i have changed topic to tasmota_%06X and it startet working =)
