ERROR [main] Error reading BMS: unsupported operand type(s) for &: 'NoneType' and 'int'

I already tried "install_newer_bleak", "bt_power_cycle" and with ot without "keep_alive"
Not quite sure how to get a complete log, down below are pieces of logs which I got from the addon logs tab with careful refreshing and copy...

Using a "DIGITUS DN-30210-1" external Bluetooth Adapter with a USB Extension, Bluetooth Integration in HomeAssistant is working, other integrations that use it also work!

If any more info is needed please let me know.

I get similar errors.

ERROR:

HA Core: 2024.5.3
HA Supervisor: 2024.05.1
HA OS: 12.3
Bluetooth: Home Assistant Yellow / Raspberry Pi Compute Module 4
Battery: Supervolt SX-100 (2024 version)
Batmon Version: 1.78
Batmon Configuration:

- address: XX:XX:XX:XX:XX:XX
  type: supervolt
  alias: battery_sx100
  verbose: true

Without knowing any better I suspect that Batmons supervolt type needs to be updated for the 2024 version of the batteries. The new batteries have a blue top and the old batteries have a black top. The new 2024 version might have changes in the BMS / BLE communication.

Some more information just to show that the battery is visible via BLE and is generally accessible:

The BMS is accessible via the Supervolt companion app.
When searching for the battery with the ESPHome Bluetooth Low Energy Tracker the battery shows up:

address: XX:XX:XX:XX:XX:XX
name: SX100-B230019
advertised service UUID: 0xFF00
advertised service data: <empty>
advertised manufacturer data: 0x007B

According to Bluetooth-Company-Identifiers.csv 0x007B stands for Hanlynn Technologies. I could confirm this with the android app BLE Radar.

How to get the complete batmon add-on log

• install add-on Terminal & SSH (if you haven't already)
• open Settings -> Add-ons -> Terminal & SSH -> OPEN WEB UI
• execute the following command in the terminal and copy the identifier shown:
  ha host logs identifiers | grep batmon
  result:
  - addon_xxxxxxxx_batmon
• use the identifier to limit the log output to the batmon addon and display the last 1000 lines:
  ha host logs --identifier addon_xxxxxxxx_batmon -n 1000
  where xxxxxxxx obviously should be the value returned by the previous command
• you can also use the --follow option described at ha host logs --help

The error repeats itself every second ( probably because of period=1.00s ). That's why I shortened the log in this part considerably.

Hi,
apparently they changed the BLE characteristic UID. Someone needs with this BMS needs to run service_explorer.py

[nightcat91]

I got these documents from Supervolt in March 2024 via an email contact.
Maybe they are useful?

At least in the bt-protocol PDF there are some UUIDs on the last page and a lot more info about the full BT protocol in general.

bt_protocol.pdf
https://support.supervolt.de/attachments/token/VsJUkKGbW5zPzOdH5dM5MZbqt/?name=%5BB%5D+bt+protocol.pdf

rs485_protocol.docx
https://support.supervolt.de/attachments/token/rCajBS0UYSQo4cwcP0ugLNWxF/?name=%5BB%5D+rs485+protocol.docx

[tinkercasa]

Executing service_explorer.py confirmed that the UUIDs near the end of the PDF [B] bt protocol.pdf are correct.

@fl4p
Will it be possible to fix the Supervolt integration with the new UUIDs?

I would love to test it once available. Thanks
