 # Pylontech Battery Monitoring via WiFi
 
-This project allows you to control and monitor Pylontech US2000B batteries via console port over WiFi.
+This project allows you to control and monitor Pylontech US2000B and US2000C 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.
+  * Adds WiFi capability to your Pylontech US2000B/C 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

 # Parts needed and schematics:
   * [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).
+  * US2000B: Cable with RJ10 connector (some RJ10 cables have only two wires, make sure to buy one that has all four wires present).
+  * US2000C: Cable with RJ45 connector (see below for more details).
   * Capacitors C1: 10uF, C2: 0.1uF (this is not strictly required, but recommended as Wemos D1 can have large current spikes).

+# US2000C notes:
+This battery uses RJ45 cable instead of RJ10. Schematics is the same only plug differs:
+  * RJ45 Pin 3 (white-green) = R1IN
+  * RJ45 Pin 6 (green)       = T1OUT
+  * RJ45 Pin 8 (brown)       = GND

   * If you want MQTT support, uncomment line 17 and fill details in lines 21-24
   * Upload project to your device
   * Connect Wemos D1 mini to the MAX3232 transreceiver
-  * Connect transreceiver to RJ10 as descibed in the schematics (all three lines need to be connected)
-  * Connect RJ10 to the serial port of the Pylontech US2000 battery. If you have multiple batteries - connect to the master one.

   * Connect Wemos D1 to the power via USB
   * Find what IP address was assigned to your Wemos by your router and open it in the web-browser
   * You should be able now to connunicate with the battery via WiFi
