IndexError on retrieving temperature data

[Morg42]

Hi,

I'm running an E3/DC S10E, pye3dc 0.9.2 and e3dc_to_mqtt 0.0.19. Periodically, I get exceptions:

2025-10-05 20:59:16:ERROR: exception in main loop
Traceback (most recent call last):
  File "/usr/local/e3dc/e3dc_to_mqtt/e3dc_to_mqtt_base.py", line 164, in run

                                    ~~~~~~~~~~~~~~~~~^^^^^^^^
IndexError: list index out of range

The program crashes when sensor becomes 5. I tried printing the temperature_raw and info data:

info:

returning BAT_DCB_NR_SENSOR as 35,

temperatures_raw:
('BAT_DCB_ALL_CELL_TEMPERATURES', 'Container', [('BAT_DCB_INDEX', 'Int32', 2), ('BAT_DATA', 'Container', [('BAT_DCB_CELL_TEMPERATURE', 'Float32', 27.600000381469727), ('BAT_DCB_CELL_TEMPERATURE', 'Float32', 30.200000762939453), ('BAT_DCB_CELL_TEMPERATURE', 'Float32', 30.600000381469727), ('BAT_DCB_CELL_TEMPERATURE', 'Float32', 28.600000381469727), ('BAT_DCB_CELL_TEMPERATURE', 'Float32', 29.0)])])

returning only 4 measure values.

I changed the code to hard return -1 if sensor > len(temperatures_data), but this doesn't seem right.

Any ideas what creates this error? (Do I really have 35 (36?) temperature sensors with 3 battery packs?)

I ran into the same issue and opened a simple PR to fix this. In my case BAT_DCB_NR_SENSOR returns 35, while i have 5 actual temperature sensors.
