# Pylontech Battery Monitoring via WiFi # Pylontech Battery Monitoring via WiFi
Forked from irekzielinski/Pylontech-Battery-Monitoring
This project allows you to control and monitor Pylontech US2000B, US2000C and US3000C batteries via console port over WiFi. This project allows you to control and monitor Pylontech US2000B, US2000C and US3000C batteries via console port over WiFi.
It it's a great starting point to integrate battery with your home automation. It it's a great starting point to integrate battery with your home automation.
