The guide will show you how you can set up a raspberry pi, old laptop or NUC (needs to have a BLE card!) as a server that will pull data Contribute to chipsi/esphome-jk-bms development by creating an account on GitHub. 1 question about esphome-pipsolar:if I use Mqtt version,will I be able to use commands to set inverter paramenters? Es:PCPxx,Change charging A,Battery Hallo Zusammen, ich bin etwas am verzweifeln mit meinem neuen JK BMS. 12500 V Hello all. Hallo, ich empfange keine Daten vom BMS. The ESP32 then sends the required CAN bus data to the inverter via a TJA1050 CAN bus transceiver. My question is; Connecting to the battery also is my Sunsynk (also with a 2. Hello. Weder mit einem ESP 8266 noch über ein ESP32 mit BLE bekomme ich Daten nach Home Assistent. Another question to ask yourself regarding the power supply of the ESP32 is what behavior do you want in case of BMS failure, alarm or simply when working on a battery. I have both of those up and running feeding info to HA. esp32_ble_jk-bms-can. 2 CAN board: M5Stack CAN Unit ca-is3050g Multi-BMS: yes Remarks: Best solution for the incomplete/wrong protocols Ok. Hi, I simply want to read UART data with ESP32 using GPS PORT. Hat jemand eine Idee? ESPHome component to monitor and control a Jikong Battery Management System (JK-BMS) via UART-TTL or BLE - syssi/esphome-jk-bms Contribute to AlexParshin79/jk-bms development by creating an account on GitHub. Monitor multiple JK-PBx (hw v14 & v15) using RS485 internal network. Is there a way to do this? Forums The esp32 talks to the BMS with bluetooth and relays that information to home assistant via wired or wireless. My ESP32dev board is able to connect to JK BMS via BLE only once after flashing ESP32 board via USB. Using bluetooth on the Home Assistant host system, it does not need any additional hardware (no USB/Serial/RS485). 12500 V with UART is lighter and more stable but in this case you have to isolate the UART connection to JK-BMS. Hey there, I am using a JKBMS with my solar installation and a 5kWh LFP battery plus a Raspi to make it all work as intended. yaml to my ESP32, I can acces from EH, it's online but I don;t know how to connect it to my JK bms via BT. If you connect the BMS to TXD (GPIO1) and RXD (GPIO3) the BMS receives the boot-up messages every time you restart the ESP. Hello, I am planning to use: - Voltronic Axpert max 8000 all-in-one inverter - JK bms 200A - 16x 304 eve cells I know this inverter has a custom setting option where you can setup all the relevant voltages which suit the battery pack being used. 12500 V with 3 decimals of accuracy [sensor:127]: 'jk-bms cell voltage 2': Sending state 4. 07 ESPHome component to monitor and control a Jikong Battery Management System (JK-BMS) via UART-TTL or BLE - esphome-jk-bms/README. I use in this project all the data i can find online, i know am not the first on this road if u have documents of other BMS protocols u can share it with me. 4. md at main · Uksa007/esphome-jk-bms-can You signed in with another tab or At ~12am on 12/5 I know SOC was 62%, at 3am Cell_Min_V was 3. So I got a new JKBMS B2A20S20P in the const char* device name = "JK-B2A20S20P"; it had to be changed so that the ESP connects to the JK via bluetooth: constchar Solarix PLI over RS232, and a bistable relay control - jwagnerhki/solarix-jk-bms-esp32 Skip to content Navigation Menu Toggle navigation Sign in Product GitHub Copilot Write better code with AI Security Find and fix vulnerabilities Automate any With the old JK-B series all BMS are connected to the ESP32. so . The potential issue with this one is that your Home Assistant computer would need the bluetooth adapter close to the BMS. XW Software: V11. 3. There is a pad that needs to be bridged near the IN/OUT print. bndy jlolajjy pfbqgxy rlfias ckwa vrsja vmwbe psxb ufraq xyuck
