Monitoring Software-Solar Assistant, JK-BMS, ESPHome and Home Assistant

- 2 LV6548''s, and Victron smart shunt using Solar Assistant. - Finally after all this time!... an easy way to monitor my JK-BMS 2amp balancer using ESPhome (Bluetooth Version install) that I found here. The JK-BMS monitoring was the last piece of the puzzle and I have screwed around for many many hours to only be disappointed until now.

Monitor JK BMS with Solar Assistant?

I do (I don''t have JK BMS though). I have it connected using the Victron cable to my Solar Assistant Raspberry Pi. It works and was easy to set up but there are some issues with the data in SA. The battery dashboard shows the data from the Victron Smart Shunt correctly but not all the data is making it to the charts tab, e.g.

My Inverter prefer fix charge voltage. I observed some dedicated BMS shipped with whole pack of high quality battery over months connected to the inverter via Rs485 and it only applies a single voltage 56V during the charging and sometime does resetting SOC by trying to lengthen the charging process to make cell be as close to 3.45 as better.

@MrPablo: by the way, unless I misunderstand something, it should be possible to use 2 x CAN OR 1 x CAN + 1 x RS485 OR 2 x RS485 on each ATOM S3 Lite . OR + OR + OR + Just some food for though concerning multi-battery communication. But if each JK BMS communicates via BLE/Wire to one of these slaves, then you send everything via CAN/RS485

Full Charge Behaviour (JK BMS) | DIY Solar Power Forum

DIY Solar Products and System Schematics. United Kingdom. Apr 22, 2023 #1 Hi all. When it is fully charged (via a Multiplus on 230V shore power supply), the JK BMS cuts the charging off due to Cell Voltage Over Voltage Protection (14.4V, 3.6v/cell). The battery then stops charging.

First AtomS3 doesn''t have many GPIOs, it would be possible to supervise 3x UART JK-B BMS by soldering wires on the Atomic CAN bus base. JK-PB BMS can all be supervised from a single pair of GPIOs via the RS485 network. With the solution below you can monitor max 15 JK-PB BMS (in production at a user with 7x JK-PB).

Pulling the data into Home Assistant through the UART port connected to an ESP32 chip running ESPHome. The ESP chip sends all the data from the bms over Wifi. I have a new JK BMS coming in the mail - planning to set that up the same way this weekend with ESPHome. This one however I can connect via bluetooth instead of having to hard wire it.

How-to? Monitor Solark, victron shunt, jk bms

Colorado, United States. Sep 30, 2024 #2 Hey, while I don''t have a sol-ark, I am doing something similar. You can use the Smart shunt as a stand alone to verify/confirm the bms/Solar assistant data. JK''s can be dialed in for very accurate SOC. As far as I know bms brand mixes or bms plus shunts won''t work together with Solar Assistant.

How accurate is solarassistant BMS?

Let SolarAssistant perform it's own state of charge (SoC) calculation by counting power flowing in and out of the battery. This is a good fallback option for anyone who can't get a real BMS reading. It's less accurate than a Victron BMS but much more accurate than the standard voltage based readings of an inverter.

Does JK BMS have an active balancer?

All JK BMS models that we stock have an Active Balancer built-in for 4S or 8S 200A LiFePO4 battery with Bluetooth & temperature sensor.

How do I configure a JK BMS to use 4g-gps?

When using the port on the left, you need to configure the BMS to use the "000 - 4G-GPS" protocol using the official JK BMS software. This is the protocol also used by the original JK BMS.
