No response received after updating to v3

[NosIreland]

Been running Seplos bms since the start on older version. Decided to update to the latest one and now not getting any readings just no response received. Here's the snippet.

[20:42:24][D][modbus_controller:037]: Modbus command to device=0 register=0x1118 countdown=0 no response received - removed from send queue

The new sensor config is very different to what is used to be. Also my RX/TX pins are different but I that is not an issue here since it worked fine before update tx_pin: GPIO1 rx_pin: GPIO3

[syssi]

Could you provide your config?

Here you go. BTW: my seplos is the original v1
