doreks commented 7 months ago

Any idea why I am not able to get any data?

here release of bms jk:

HI please big boss @syssi , could you give me some of your words of wisdom? :-)

syssi commented 7 months ago

Could you provide a photo of your wiring? Please make sure GND is connected properly. If all three wires are connected properly to GPIO1, GPIO3 and GND and aren't swapped (RX vs. TX) there are a few options left:

Sometimes GPIO1 and GPIO3 cannot be used because the USB-to-TTL chip of the dev board interferes. Please try GPIO4 + GPIO5 (this is possible because ESPHome uses SoftwareSerial if there is no hardware UART available) instead.
Please try a ESP32. I'm aware of many people without success using an ESP8266 dev board.

doreks commented 7 months ago

thanks @syssi for your words, time and and and support!

finally I could solve the problem by changing the HW to another ESP :-/ I now have a couple of questions, the first one I don't see any switch for balancing, in the photos of the caputaras of this project I see it but I don't observe in the code anything about this. The same thing happens for the value of resistance Ω, I don't see any reference so it doesn't load anything. Is there any way to get this data?

here config esp: https://pastebin.com/BJi1bV8m

Captura1 Captura2

again thank so much for support!

syssi commented 7 months ago

Bluetooth and serial communication are using different protocols. The protocol of the serial communication doesn't provide any details about the resistance and balancing current. You have to use BLE if you need the values.

The balancer switch isn't implemented yet (via serial connection). It's supported by the BLE component only at the moment.

syssi commented 7 months ago

Could you provide some details about your working setup? Which kind of dev board do you use and do you use a hardware UART or a SoftwareSerial connection.

syssi commented 7 months ago

@doreks Friendly reminder.

doreks commented 7 months ago

@doreks Friendly reminder.

So sorry, just give me this weekend I have plenty of family here.. On Monday will be ready..

doreks commented 7 months ago

rovide some details about your working setup? Which k

hi,

Thank you very much for your support. In my case, configuration I have would be:

DEYE 8K Inverter
BMS JK
16 LifePO4 cells connected at 16sx 304 Ah conecting bms with esp32 board and DEYE with board with can port. now everything is working and dumping information into my home assitant but what would be amazing is if DEYE could get the info from the jk bms but I have no way and no idea how to do it.

virus100b commented 5 months ago

I can confirm that using GPIO4 + GPIO5 on ESP 8266 NodeMCU that has USB to TTL chip present on board (has micro usb port) it woks. On D1 Mini the USB to TTL chip is not present on board and probably many people that use code for D1Mini and use Node MCU boards failed to communicate with BMS.

doreks commented 5 months ago

@virus100b how is your setup?

virus100b commented 5 months ago

RX, TX from GPS port JK Bms connected to GPIO5, GPIO 4 of ESP 8266 Node MCU board. External 5V supply for Node MCU. Do not use Vcc on GPS port of JK because tis Vcc is the 16S battery voltage (48-55V)

baturinivan commented 2 months ago

I have similar issue. esp32 dev kit was working fine for some months, then communication starts to break down. Change of the esp to new one solved the problem, but after a month of usage comes again. Inverter communication is ok, but bms is not. Changing of the port pins doesn't solve the problem either....

I have reflashed couple of times, seems to be working, so I will monitor it.

baturinivan commented 1 month ago

I have reflashed couple of times, seems to be working, so I will monitor it. Not for a long time. Starts to have invalid header again and then seems to gone completely. Anyone have experienced esp32 malfuntion after some usage with jk bms?
