Add JK-PB bms compatibility. Target: 1 ESP in a "listening mode" connected to RS485 network.

Open txubelaxu opened this issue 1 year ago • 65 comments

JK-PB2A16S-20P model jk-bms. Two bms connected to that RS485 internal network. ubuntu connected in a "listening mode" using a USB<->RS485 adaptor.

I have created a new component: "jk_rs485". It is for JK-PB HW v14. This is a sniffing way to gather information across the RS485 network. The goal to achieve is to gathering information about every jk-bms using only one ESP. This way, Bluetooth remains free.

To compile: esphome compile esp32-example-rs485.yaml

Pending:

  • testing
  • configure yaml with multiple BMSs. Each one: 1 address [0x00,0x0f]. So, address paramether to insert inside yaml config is pending.

I will have a look as soon as possible. Please give me some time! :-)

Sorry!! I am very newbie at github. 👏👏😉

No problem. Feel free to ask any questions.

No problem. Feel free to ask any questions.

Many thanks, Sebastian. Certainly, I do not know how to manage/arrange the "code + configuration.yaml" to demultiplex the info arraiving from RS485. So, I have got the info about every BMS connected to the RS485 network (it does not matter how many are: max 16). I know how to pass the UART information to the jk_rs485 component (but only one). But I have achieve the goal of sharing the same UART with two jk_rs485 components. I would like to:

  1. remake the configuration.yaml structure in order to place inside that file each jk_rs485 node: each one with a identifyer and an address.
  2. "publish_state" info and settings, but signaling the identifyer (not address) of the jk_rs485 node.

I do not know if this is possible.

Many thanks!!

any chance you could put a wiring diagram together so I can test with my 3 new JK BMS?

Which Ethernet wires go to tx and rx on the ESP board?

txubelaxu avatar Mar 10 '24 14:03 txubelaxu

it is not ethernet. It is RS485, ok? You need a USB to RS485 adaptor.

txubelaxu avatar Mar 10 '24 14:03 txubelaxu

USB plugs into the ESP32 dev board and RJ45 into the RS485 port in the inverter?

brycelarge avatar Mar 10 '24 14:03 brycelarge

Sorry my mistake. Forget my previous answer.

ESP TXRX to a serial2RS485 converter. From this converter to the right (any of the two) existing RJ45 connectors.

txubelaxu avatar Mar 10 '24 14:03 txubelaxu

Can you point to a code that should be loaded to ESPHome please? Is it working already? Master and Slave Sniff? I have 1 Master and 6 Slaves right now lol.

With pleasure. I will start preparing the ESP for that and write back in 24-48hrs Need the converter

Thanks for the hard work here. Quick question, is there a reason why you have all the grounds connected together in your wiring diagrams?

brycelarge avatar Mar 12 '24 08:03 brycelarge

If we have 1 master and 2 slaves what would the rs485_address be on the second slave? esp32-example-jkpb-rs485.yaml shows master at rs485_address: 0x00 and first slave at rs485_address: 0x07

brycelarge avatar Mar 12 '24 08:03 brycelarge

Master always must be 0x00. 1 master is mandatory. If no master, no data.

Slaves: any address from 0x01 to 0x0f Each slave one different address.

Thanks for the hard work here. Quick question, is there a reason why you have all the grounds connected together in your wiring diagrams?

In the converter I have used,

  1. the converter needs +5Vcc and GND
  2. the RS485 bus needs: A, B and GND "GND" point in this device is the same for 1) and for 2)

Maybe there is in the market a device to "isolate" two circuits (optocoupled). I do not know.

I have to review that. I have not changed that code but I see it was there before.

How many BMS have you connected using RS485 network? 3 (1 master and 2 slaves?

Maybe it is because is an array of temperatures, and MOS temp is a parameter independent. I will review that.

Ive made a test board as soon as the converter arrived. All went smooth, but one thing. All that my ESP is giving is BMS0 info. (i have 1 Master and 6 Slaves) The code has bms0 and bms1, i didnt implement those 5 more it is not important i guess.

Dip switches are correct (BMS's Bluetooth name changes to DIP switch number set)

Do you have an idea why i am not receiving other BMS's?

[19:39:22][W][component:214]: Component jk_rs485_sniffer took a long time for an operation (1.16 s). [19:39:22][W][component:215]: Components should block for at most 20-30ms.

Maybe my RS485 bus info is very large due to number of devices, and it doesnt complete the handshake crashing the sniffer component idk.

yaml code needs all bms references.

Send me your yaml and I could modify if you want. Tell me each bms address as well.
