# bmspy # bmspy
bmspy can be used to get information from a xiaoxiang-type BMS system. bmspy is a tool to get information from a xiaoxiang-type BMS system, using some sort of serial connection.
It can display the information as text, in JSON, or export the data continuously to a Prometheus exporter.
