I have installed clang-format (v14 now)

txubelaxu · 2024-03-03T19:32:49Z

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.

Sorry, I have changed erroneusly components/jk_bms_ble/jk_bms_ble.cpp file.
I do know how to solve this error.
Other changes are new files.

txubelaxu

Something wrong here?
It is marked as failed.

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

txubelaxu · 2024-03-05T12:30:13Z

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

syssi · 2024-03-05T12:47:18Z

No problem. Feel free to ask any questions.

txubelaxu · 2024-03-05T15:10:57Z

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:

remake the configuration.yaml structure in order to place inside that file each jk_rs485 node: each one with a identifyer and an address.
"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 · 2024-03-10T14:15:58Z

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

brycelarge · 2024-03-10T14:30:21Z

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

txubelaxu · 2024-03-10T14:33:53Z

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.

denveronly · 2024-03-10T18:57:13Z

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.

vlxxdev · 2024-08-08T17:32:47Z

@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?

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?
