Does the BMS support bluetooth? What's the advertised bluetooth name?

[syssi]

I could be a Tianpower BMS if the bluetooth name starts with TP: https://github.com/syssi/esphome-tianpower-bms

Could you start the Windows application and talk to your BMS? You can configure the protocol of the CAN bus and RS485 bus here:

Could you list all available protocols?

I Need to assembly all together and I can try sniffed protocol.

PCB board look like that: Model Number 48100-LT-60

@valdiks Is your battery pack / BMS already mentioned at the list of supported devices?

[valdiks]

I have the same Basen DIY kit with the same BMS and equalizer models. I'm running a test now, and it looks good so far.

[syssi]

@valdiks Could you tell me the advertised bluetooth name of your BMS and could you provide some more logs. In would like to lookup the device model (something like TP-LTxxxx) in your logs.

[straga]

485 Battery to Inverter

CAN Battery to Inverter

[valdiks]

ESPHome is showing the TP-LT55A model through MQTT.

[valdiks]

We have encountered a problem where ESPHome hangs when the BLE signal is weak and only a power reset helps.

@valdiks Could you tell me the advertised bluetooth name of your BMS?

[valdiks]

@syssi TP_123456, but I've changed it.
