Launch of the JK-BMS RS485 add-on for Home Assistant

[thorium]

Hello!
I'm trying to set it up with an Elfin IP Gateway and I cannot get it to work.
I am confident the Elfin is connected to the JK BMS (PB2A16S30P v19) and working properly, because this alternative project (https://github.com/luisgonzalezgonzalez/jkbms_mqtt) is successfully pulling the data from the Elfin (this is coming in from this alternative tool).
I wish to use your tool because I am going to have 4 parallel batteries soon with a master/slave.

{"battery_voltage": 53.753, "battery_power": 1433.369, "battery_current": 26.8, "cell_00_voltage": 3.36, "cell_01_voltage": 3.36, "cell_02_voltage": 3.357, "cell_03_voltage": 3.358, "cell_04_voltage": 3.361, "cell_05_voltage": 3.361, "cell_06_voltage": 3.362, "cell_07_voltage": 3.362, "cell_08_voltage": 3.363, "cell_09_voltage": 3.36, "cell_10_voltage": 3.36, "cell_11_voltage": 3.358, "cell_12_voltage": 3.36, "cell_13_voltage": 3.358, "cell_14_voltage": 3.36, "cell_15_voltage": 3.36, "mos_temperature": 29.6, "battery_temperature_1": 30.3, "battery_temperature_2": 30.8, "balance_current": 0, "battery_soc": 72}
