I have been doing some research on the seplos rs485 bus, and I have programmed a python script to "listen" the data from the complete battery pack (when there is more than one) and publish it to a MQTT server (with auto discovery for home assistant).
When there is only one battery, modbus can be used directly, but when there are several batteries the main one acts as "Master" and there can only be one master, so there is no other option but to listen to what the master asks and decode it.
The code (a draft version) is in: https://github.com/ferelarg/Seplos3MQTT
