AtomS3 Lite Bluetooth Proxy

Hey all,

I cant figure out why I cant connect Bluetooth devices to my AtomS3 Lite Bluetooth Proxy. I’ve got the M5 Atom S3 Lite module and set it up via ESPHome. The installation was done manually since the ESPHome website does not support the S3 lite yet.

I see log output via ESPHome. But when I set my Tuya Soil measure in pairing mode it is not popping up in notifications whatsoever. Can anyone have a look at my config and help me out?

Log output:

I’ve checked the mac address in the Tuya app and I can see it is listed in the verbose logs I’ve enabled too.
