Seen on forum that linked here it should work, also pbmstools worked.
Connection Type: Serial
MQTT connected with result code 0
Connecting to BMS...
trying to connect /dev/ttyACM0
BMS serial connected
Error retrieving BMS version number
Error: Error1 calculating CHKSUM: ord() expected a character, but string of length 0 found
Error retrieving BMS and pack serial numbers.
This is required for HA Discovery.

Seems there is no serial number? Can I generate and set one via pbmstools to solve this? (Also couldn't get it to connect using solar-assistant)
