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

[txubelaxu]

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.

Hi, I'm trying to install the 1 master 6 slaves yaml file and it always fails. This is what I get from logs:

I'm installing the yaml file via esphome addon in home assistant. What am I doing wrong here? Help will be much appreciated, thanks!

Hi @dgbiuro, could you try with the last update just uploaded now?

Many thanks!!

[jogybaer0815]

Latest ESPhome update needs changes:

'talk_pin' is a required option for [0]

• id: sniffer0 protocol_version: JK02_32S rx_timeout: 500ms uart_id: uart_0

Where should talk_pin assigned?

Any pin of your choice. It is not mandatory to connect tx_pin to TTL to RS485 converter. It is not mandatory to connect talk_pin to TTL to RS485 converter. Assign to "talk_pin" any free pin that can act as "output".

I have got the code to act as "master" or "pseudo-master". I am publishing this soon. Today or tomorrow, maybe.

[txubelaxu]

@denveronly, have you tried last version with your 7 BMSs? Did it work?

[kommando828]

When this is fully merged will it allow the outputs to be used to feed an MQTT broker, looking forward to this one now I have my SMA SI's in closed loop with a JK-PB2A16S20P using canbus.

My DIP switches and addresses in yaml file are the same. I have one master jk-bms and two slaves. I have shortened the code to just bms-0, 1 and 2. I didn't connect the talk pin as you said it is not mandatory.

Many thanks for helping

[txubelaxu]

hi @dgbiuro,

that is anormal network data. Is it correctly connected to the network?

Talk pin is not mandatory if you want ESP to acting only in "listening mode". It has been impossible for me to get "frame type 3rd" from master (because it is not possible to ask for that information to 0x00). It has been successed to asking for that information to any of the slaves.

[D3R-ST3FAN]

BTW, what do you think of this board for your project? https://github.com/Xinyuan-LilyGO/T-CAN485

I have it laying around from previous project that i was unable to comply due to CAN issues here and not the best specifications of the board (and obviously my knowledge) For RS-485 it can be pretty clean install without soldering i think.

I configured RX GPIO21/ TX GPIO22 as per their documentation. No luck. Maybe there is a driver that needs to be included. Did you have any luck yet using this board?

[txubelaxu]

With last changes, Balancing, Charge and Discharge switch are now working in read & WRITE mode. There is a new setting inside "sniffer" part in the yaml to enable the "broadcast" to all the BMSs when you change one of those switches.

[vpritulin]

@txubelaxu Hi! I'm trying to understand your project and if I understood correctly, you connect the inverter to the battery via rs485 via CAN bus and simultaneously receive data from the inverter also via rs485 or is it not quite like that?

@brycelarge Did you try a clean build? esphome clean yourconfig.yaml; esphome run yourconfig.yaml or press the CLEAN build files button at the ESPHome dashboard.

same here: i added for the last updates "broadcast_to_all_bms: True" and that was fine but after the latest updates of ESPHome it is an invalid option. But commenting this offers more errors :( What is going on and what is the solution? Regards

I'm using 1 master and multiple slaves. I have cleaned build files, also physically SSH into esphome container and deleted all the files in the components dir but still the same error persists. Any ideas?
