Add NEEY/Heltec 4A balancer support #109

syssi · 2022-05-11T19:36:15Z

The android apps aren't obfuscated. It should be possible to extract details about the protocol / frame structure and content.

syssi · 2022-05-11T19:46:12Z

Do you own a NEEY or Heltec 4A balancer and a Android device with the app installed? Please provide a btsnoop capture which can be easily created if you follow these instructions:

https://medium.com/@charlie.d.anderson/how-to-get-the-bluetooth-host-controller-interface-logs-from-a-modern-android-phone-d23bde00b9fa

The capture is helpful to replicate the behavior / BLE frames of the Android app to talk to the BMS using this component.

Hi,
In this moment I don't have a balancer, I order one NEEY today, when he arrives I'll let you know here and we'll do tests.
Cristi

syssi · 2022-05-13T06:22:41Z

I know. I just tried to inform you if you own the device some day we could give it a try to add device support.

cristi2005 · 2022-05-13T07:09:26Z

Thank you for the great news and involvement.

cristi2005 · 2022-07-29T18:32:17Z

Hi I have a Neey balancer, I prepare a phone settings for developer otions....... I downloaded adb files, I conected the phone on laptop, run powershell:

#!/bin/bash
OUTPUT_DIR=$(pwd)
pushd /tmp
echo "Getting Bug Report..."
adb bugreport bug
echo "Unzipping Bluetooth HCI Log..."
unzip bug.zip FS/data/log/bt/btsnoop_hci.log
echo "Copying btsnoop_hci.log to '$OUTPUT_DIR' ..."
cp FS/data/log/bt/btsnoop_hci.log $OUTPUT_DIR/$(date +"%Y%m%d_%H%M%S")_btsnoop_hci.log
echo "Cleaning up..."
rm FS/data/log/bt/btsnoop_hci.log
rm bug.zip
popd

And have a lot of errors and not create btsnoop capture.
If you have some time to help my with the capture please leave message here.

Thank you,
Cristi

syssi · 2022-07-29T18:41:26Z

Are you sure the bug.zip did not contain a "btsnootlog"?

unzip bug.zip
find . -name btsnoop_hci.log

cristi2005 · 2022-07-29T18:43:41Z

Only this 4 file:

bugreport-2022-07-29-21-20-00.txt
dumpstate_log.txt
main_entry.txt
version.txt

cristi2005 · 2022-07-29T18:46:03Z

If you want can allow a remote desktop with AnyDesk ?

syssi · 2022-07-29T19:00:49Z

I will provide some additional instructions tomorrow. I assume some important steps of the capturing process are missing. I've to verify some steps locally to provide better instructions. Probably just a "Bluetooth off + Bluetooth on" is missing to trigger the traffic capture. Please start the NEEY app as next step and connect to the BMS. The to retrieve the bug report again. This time the file should be part of the dump. If not we could try to retrieve the dump manually from your device using adb. Where are you from / at which timezone do you life? I've some free time for a anydesk session tomorrow.

cristi2005 · 2022-07-29T19:05:59Z

I am from Romania, it's ok for me tomorrow, I'm at home all today and can tested all necesary.
Give me a sign tomorrow when you have time and we'll do the tests together.

syssi · 2022-07-29T19:13:54Z

Alright. I will ping you tomorrow!

cristi2005 · 2022-07-29T19:16:45Z

Ok, good nyght.

syssi · 2022-07-30T08:22:10Z

Could you tell me the Android version of your device?

cristi2005 · 2022-07-30T08:24:54Z

8.0.0

syssi · 2022-07-30T08:33:05Z

I tried the following with my Android 9 phone:

Enable ADB
Enable Bluetooth HCI snoop log
Turn off bluetooth + turn on bluetooth
Start the BMS app and play around
Generate a bug report containing the capture adb bugreport bug
Unzip the bug.zip and copy the FS/data/misc/bluetooth/logs/btsnoop_hci.log:

Is your phone rooted? If yes we could try this approach: https://stackoverflow.com/a/58384046

Can you asist me on AnyDesk ?
If is yes where send AnyDesk ID ?

cristi2005 · 2022-07-30T08:49:23Z

Finaly I have BT snoop log, I send an email to see if ok ?

cristi2005 · 2022-07-30T08:50:40Z

I send on email.

works with your steps:

Enable ADB
Enable Bluetooth HCI snoop log
Turn off bluetooth + turn on bluetooth
Start the BMS app and play around
Generate a bug report containing the capture adb bugreport bug
Unzip the bug.zip and copy the FS/data/misc/bluetooth/logs/btsnoop_hci.log:

Could you provide some screenshots of the android app? This will help me a bit to understand what's available/exposed and whats internal + what can be controlled and what's read-only.

cristi2005 · 2022-07-30T09:42:24Z

I attached a pic, If you need somthing ... please tell me.

syssi · 2022-07-30T09:52:17Z

I attached a pic, If you need somthing ... please tell me.

Thanks! Could you explain the purpose of the Run: switch which is turned on at the moment?

cristi2005 · 2022-07-30T09:58:24Z

Turn on or off balancer, if is on, on balancer sounds a bip buzer and balancer turn on and cell begin balanced, if switc turn off, on balancer sound a bip buzer and balancer turn off and stop cell balancing. I hope you understand I write here…

syssi · 2022-07-30T10:02:52Z

I would be happy if you could create another traffic capture while turning balancing on and off multiple times. I would like to capture the balancing on/off commands.

cristi2005 · 2022-07-30T10:10:01Z

I attached your request.

cristi2005 · 2022-08-08T17:26:45Z

Yes is correct.

cristi2005 · 2022-08-08T18:07:59Z

log.txt

When I set the current in Homeassistant, it is also set in Balancer, I checked with the Android application, I have attached pictures.

syssi · 2022-08-08T18:14:32Z

Looks good to me. No issues found. Correct? In this case only the error bitmask is missing + some documentation and we are feature complete. Do you miss something?

cristi2005 · 2022-08-08T18:19:44Z

Only the missing problem above, the one with the missing entities after restarting Homeassistant. Can't you set those entities to load automatically after the HA restart?

syssi · 2022-08-08T18:30:27Z

You could add an automation to your HA setup to press the retrieve settings button automatically on startup (once).

syssi · 2022-08-08T18:34:00Z

If the periodic beep isn't a problem we could add the retrieve settings call to the yaml configuration.

cristi2005 · 2022-08-08T18:36:56Z

If the periodic beep isn't a problem we could add the retrieve settings call to the yaml configuration.

Ok

cristi2005 · 2022-08-08T18:37:37Z

You could add an automation to your HA setup to press the retrieve settings button automatically on startup (once).

this is also an option

syssi · 2022-08-08T19:27:14Z

If the periodic beep isn't a problem we could add the retrieve settings call to the yaml configuration.

You could add this approach to your configuration: 54f5b19

syssi · 2022-08-08T20:34:48Z

Take a look at the full file: https://github.com/syssi/esphome-jk-bms/blob/79d6016c98388e0cda4f7d981de7153adfaf4372/esp32-heltec-balancer-ble-example.yaml

It's important to assign an id to the retrieve settings button to be able to use the button at a action.

The last two text sensors are also new but unrelated:

text_sensor:
  - platform: heltec_balancer_ble
    errors:
      name: "${name} errors"
    operation_status:
      name: "${name} operation status"
    total_runtime_formatted:
      name: "${name} total runtime formatted"
    buzzer_mode:
      name: "${name} buzzer mode"
    battery_type:
      name: "${name} battery type"

I've merged the NEEY balancer support into main. Please update configuration yaml to:

Have any ideea about this error's ?

Thank you,

Please update ESPHome. Version 2022.9.3 is required as minimum.

cristi2005 · 2022-10-13T05:37:39Z

Thank you, working now.

chfink0 · 2023-01-15T14:22:58Z

Hey guys, first of all, thank you very much for this integration. Does this work with multiple Balancers? I do have 5 of them :-)

Thank you in advance!

syssi · 2023-01-15T14:43:07Z

A single ESP32 is limited to 3 simultaneous BLE connections. See https://esphome.io/components/ble_client.html

chfink0 · 2023-01-15T14:52:20Z

Ok cool. Thank you. So I could just take two of the ESP32 boards I guess. But where can I set the 2nd and 3rd mac adress? Thank you!!

syssi · 2023-01-15T15:26:39Z

Take a look at this JK-BMS example: https://github.com/syssi/esphome-jk-bms/blob/main/esp32-ble-example-multiple-devices.yaml#L54-L87

You have to add multiple BLE Clients blocks to the YAML and load the custom component multiple times. Please keep in mind the example above is for the JK-BMS. You have to replicate the pattern/schema for the balancer example.

chfink0 · 2023-01-15T15:40:12Z

Excellent, seems doable, thank you very much!

hi everyone. im using home assistant OS on rasp. pi 3. can i connect with bluetooth direct rasppi to neey balancer without esp32. sorry bad English.

syssi · 2023-04-07T10:22:41Z

This implementation/project requires a ESP32. I'm not aware of other (Linux based) projects supporting the device.

you are perfect. but raspberry pi have a bluetooth. I asked because I was wondering if it could be done without the need for other hardware.

syssi · 2023-04-07T10:59:06Z

This implementation requires ESPHome / a ESP32 device as foundation. It cannot be ported to Linux / a Raspberry Pi easily.
