TSL2561 not detected

ESPHome
1

Hello,
Hardware:
ESP32-WROOM-32D
Seed TSL2561 x4
Seed Multiplexer TCA9584A

I have issues to get real values and the multiplexer does not really split. Any ideas on that?

Ok, figured it out. But now i have issues that TSL2561 gets not detected if connected to TCA9845A.
