BT270-2 is Daly DL-
And LT40AH is a LionTron

Why "No supported devices found" is shown?

We use also the internal HA Bluetooth Integration and the Xiaomi BLE.

Many thanks. This Integration seems to be realy great.

[patman15]

Can you please provide the output of bluetoothctl info <MAC> for both devices? Then I can check, why they are not recognised. Thanks!

• Regarding the LionTron, it is not officially supported yet, I'm waiting for someone to confirm that this branch:https://github.com/patman15/BMS_BLE-HA/tree/141-liontron-batteries works. So if you could manually install the branch, verify that the LionTron is detected, and send me a debug log of it, I could merge it to the next release.
• Currently, a Daly BMS is required to have a name DL-* to be detected. I might need to relax this requirement. Can you rename the battery and check?

[iNETTechnik]

such a great job, important app. it is a gamechanger, so i do not have to connect a daly usb cable or daly2mqtt.
many many thanks.
i renamed it and instantly it was shown in HA without any other work todo (very nice autodiscovery).

Hope the connection is static, may because the BMS sends bluetooth to sleep to save power.

[iNETTechnik]

seems it works. question:
how often the data is recieved / updated ? every 30s i read. hope this is not so much energy from daly BT dongle.

can you send me the branch? your link links to this issue.
how can i add this to HA via HACS? how can i get branches there?

many many many thanks

[patman15]

Correct.

can you send me the branch? your link links to this issue.

Sorry, I accidentally copied the wrong link. Here it is: https://github.com/patman15/BMS_BLE-HA/tree/141-liontron-batteries
Note that you might loose autodetection for the Daly again, as it is based on an older version. I need to merge the two still. It won't affect though, as long as you keep the battery installed and do not remove it from the integration.

many many many thanks

You're welcome! 😃

[iNETTechnik]

ok i use
git clone https://github.com/patman15/BMS_BLE-HA --branch 141-liontron-batteries
and restart HA... we will see

[iNETTechnik]

ok seems not finding the Liontron Battery. is the nameing is important there?

No, not at the moment, but it seams the LionTron does the same crap as ECO-WORTHY, i.e. use the MAC address as manufacturer_id. 🤦 So I need to change the auto detection to something with the name. 😞

[iNETTechnik]

i replaced /homeassistant/custom_components/bms_ble with the files of the branch 141-liontron-batteries, but no LionTron Batterie connected.

Device 40:17:12:01:11:97 DL-BT270-2
Daly Bulltron, works well with this branch and "version": "1.11.4"

[iNETTechnik]

🤦 So I need to change the auto detection to something with the name. 😞

sorry about this. may there is a manual mode to add batteries by MAC ?

thanks so far

[patman15]

So far I hoped to make it really easy for the user and implement an auto-detection, but not sure how long this will hold true with all those sloppy Chinese pop-up vendors of batteries. 😎

[iNETTechnik]

oh yes, good approach, but with so many exceptions and sloppy implementations. I know that well too :/ but thanks for the effort! What you're doing is really great. thumbs up :D

[patman15]

@iNETTechnik Can you please update your branch, it should fix all LionTron batteries. I'm still working on the Bulltron/Daly and will report back soon.

[iNETTechnik]

great work. thanks.
many thanks. batteries are shown, but connection error during initialisation.
i but the debug log there: #146
@patman15

[iNETTechnik]

btw:
i renamed my bulltron to BT270-N , originally it is DL-nnnnnnnnn or so.

Hallo,

ich habe in meinem Wohnmobil 2 Life Batterien von Kepworth. Die DL-Life1 wird erkannt und die Life2 wird nicht erkannt. Kann mir da jemand einen Tipp geben?

Konfiguration:

v1.12.0 BLE Battery Managemen

Core: 2025.2.4
Supervisor: 2025.02.1
Operating System: 14.2
Frontend: 20250214.0

Danke für die Hilfe

Hi!

Because these manufacturers using Daly BMS do not manage to configure sensible manufacturer_id values. 😠 In such cases you need to have the name of the device starting with DL-. Your second battery does not fulfill that condition.

Best regards,
Patrick
