# Pylontech Battery Monitoring via WiFi
|
|
|
|
This project allows you to control and monitor Pylontech US2000B batteries via console port over WiFi.
|
|
It it's a great starting point to integrate battery with your home automation.
|
|
|
|
Features:
|
|
- Low cost (around 20$ in total).
|
|
- Adds WiFi capability to your Pylontech US2000B battery.
|
|
- Device exposes web interface that allows to:
|
|
* send console commands and read response over WiFi (no PC needed)
|
|
* battery information can be retrevied also in JSON format for easy parsing
|
|
- Easy to modify code using Arduino IDE and flash new firmware over WiFi (no need to disconnect from the battery).
|
|
|
|
Parts needed:
|
|
- [Wemos D1 mini microcontroller](https://www.amazon.co.uk/Makerfire-NodeMcu-Development-ESP8266-Compatible/dp/B071S8MWTY/).
|
|
- [SparkFun MAX3232 Transceiver](https://www.sparkfun.com/products/11189).
|
|
- Cable with RJ10 connector (some RJ10 cables have only two wires, make sure to buy one that has all four wires present).
|
|
- Capacitors C1: 10uF, C2: 0.1uF (this is not strictly required, but recommended as Wemos D1 can have large current spikes).
