Hi,

After being able to integrate your amazing pipsolar package for my axpert max I aka PIP8048, now I am trying your JKBMS Integration.
Actually it's plugged on the hardware UART0 GPIO01/GPIO03.... Unfortunatly absoluptly no oommunication is logged :(
Here is my little yaml

Where did you buy the BMS? Could you ask the seller about some specifications?

syssi commented Feb 15, 2022

Please avoid the first UART it's used by the logger. If you disable the serial logging by setting the baud rate to 0 the ESP still writes some messages to the UART on boot-up (bootloader etc.). Just use any other GPIO. "All" GPIOs of an ESP32 can be used as hardware UART.

Yes I know I should avoid the UART and I disable the baud_rate: 0.... but the problem is I am using the two other UARTs of the ESP32.... and in order to let work, one of the three must be an hardware as far I understood.... Now I am doing some test with a standalone ESP32... I will check via software UART. What GPIO are you advised ?

syssi commented Feb 15, 2022

There is no software UART implementation (in Esphome) if you use a ESP32. The ESP32 supports 3 hardware UARTs (auto-assigned by some internal matrix).

Software serial is a thing if you use a ESP8266. The ESP8266 doesn't have a "matrix" to wire some features (UARTs) internally. The hardware UARTs are assigned to some selected GPIOs. If you use another GPIOs (which doesn't support hardware UART) the software serial implementation is used (automatically).

syssi commented Feb 15, 2022

In other words: If you use vanilla ESPHome + ESP32 the maximal number of UARTs is limited to 3.

I prefer this setup for poking around on a D1 Mini ESP32:

uart:
  id: uart0
  baud_rate: 115200
  rx_buffer_size: 384
  tx_pin: GPIO14
  rx_pin: GPIO4
  debug:
    direction: BOTH

Ok :) ...Actually I am testing on a vanilla ESP32 with one unique softUART (04/14) as in your yaml.
and it's working .... Even the choice of GPIO04 is not perfect since the ESP32 don't boot correctly. I need first to disconnect the UART connexion :)

Hummm seems I wrote too fast... I had two data sequence ... then anything more :(

Do you see anything at the logs? If the ESP32 reboots/crashs please try to reduce the number of sensors.

I guess I need to recompile in very_verbose for the logger :)

Please check your wiring and try to swap the wires again.

Another user had success using GPIO16 and GPIO17: #35

Ok first very_verbose in GPIO04/GPIO14

For the wiring ... it's so simple except if the black wire from the RS485 was not the ground :) .... but I guess it's the case

Going to wire with GPIO 16/17

Could you provide a photo of your setup?

Ok I will try...... coz the BMS is in woodbox.

UART cannot work if you use 2 wires only. You have to attach RX, TX and GND!

This is the important part of the capture:

# Request
[14:49:45][D][uart_debug:114]: >>> 4E:57:00:13:00:00:00:00:06:03:00:00:00:00:00:00:68:00:00:01:29

# Response
[14:49:45][D][uart_debug:114]: <<< 4E:57:00:13:00:00:00:00:06:03:00:00:00:00:00:00:68:00:00:01:29

It looks like the response isn't a valid response from the BMS. It could be some echo / crosstalk / short circuit / missing GND issue because there is no difference in the Request (TX) and the Response (RX).

Ok ... I will check that point.... I just soldered a connector (JST XH 3p) from the provided cable. I will by able the check not before 2h. Anyway thanks for your Huge help ...

Here are some picts

https://ibb.co/nb2XqgH

So I wired a cable JST XH 3P, 15cm
RS485 <=> JST XH 3P
black <=> black
yellow <=> yellow
white <=> red

Then from this femmal cable into the ESP

The other part of the RS485 is correctly plugged into the JKBMS

I had a very similar output to yours above but then I switched to:

uart:
  id: uart2
  baud_rate: 115200
  rx_buffer_size: 384
  tx_pin: GPIO16
  rx_pin: GPIO17

I have a slightly different BMS than yours but at least on my GPIO16 goes to the pin closest to ground and GPIO17 goes to the pin closest to V_Batt

It's been working well for days now.

Can you confirm to me that triplet color from your RS485 module are (black, white, yellow) and black is the ground ?

In fact, what are the A/B colors respectively ?

I don't have the RS-485 module. I made a custom cable that fits the RS-485 port on the BMS.
You can check which ports are +V_Batt and GND with a multi-meter, and that just leaves two other pins for TX&RX that you can just try one way and then another, but as I said above the pin closest to ground on mine is what goes into GPIO16 on the ESP.

You mean you attacked directly the RS-485 port from the JKBMS to the ESP32 without using the module ?

Correct,
Per the schematic in the instructions: https://github.com/syssi/esphome-jk-bms

OMG :) maybe it's the trick ..... Hope I have somewhere some JST picoblade 1.25mm 4P :) ..

Maybe ...
But I do have a different model BMS so I can't say for sure.
Mine at least is Molex PicoBlade 1.25mm 4P

I am lucky tonight ..... I found an old molex 1.25mm 4p connector :).... I will be able to test asap

The manual looks good to me. It's the implemented protocol.

Good news :) It's WORKING fine :)

And FYI, it's also working fine on my "PVbrain" ..... 3 UART used : JKBMS,PIPsolar and dual PZEM 004T :)

Do you use the official PZEM component? I'm aware of one bug report telling the component is unstable.

Yes ... I got some since 2 years ..... Super stable for me....

Cool! I will use one of these devices (PZEM-017 DC 0-300V 100A) as digital shunt in future.

maybe ... I was not clear, the PZEM I installed are PZEM 004T V3 (modbus based). I don't plan to install the DC version with a shunt. The problem, the sens of current is not reported with PZEM ... it's big problem IMHO for solar application.
I bought such module.... : https://fr.aliexpress.com/item/4000762882822.html?gatewayAdapt=glo2fra&spm=a2g0o.9042311.0.0.27426c37To8Uh6
There is a UART port .... maybe a good excercice for hacking something.
