get_battery_data: 'NoneType' object cannot be interpreted as an integer

Get this error when i run e3dc-to-mqtt (https://github.com/mdhom/e3dc-to-mqtt)

File "/home/pi/gitstuff/e3dc-to-mqtt/e3dc_to_mqtt/e3dc_to_mqtt_base.py", line 164, in run

Pasted the code and the error to ChatGPT:

The error message you provided indicates that there's an issue in the _e3dc.py file, on line 1324, where the code is attempting to iterate over a range with sensorCount as the upper limit. However, it seems that sensorCount is None, hence the error.

To help you further, I will inspect the _e3dc.py file, specifically around line 1324, to identify the source of the problem and suggest a potential solution.

From the code snippet, the error occurs at this line:

for sensor in range(0, sensorCount):

Here, sensorCount is expected to be an integer, but it's returning None. The value of sensorCount is determined by the line:

sensorCount = rscpFindTagIndex(info, "BAT_DCB_NR_SENSOR")

It seems that the function rscpFindTagIndex might be returning None when it doesn't find the specified tag within the provided data (info in this case).

To resolve this issue, you could:

1. Ensure that the tag "BAT_DCB_NR_SENSOR" is present in the data.
2. Add a check to handle the case when sensorCount is None.

Here's a suggestion on how to handle it:

sensorCount = rscpFindTagIndex(info, "BAT_DCB_NR_SENSOR")
if sensorCount is None:
    sensorCount = 0  # Or handle this case in some other appropriate way
for sensor in range(0, sensorCount):
    ...

This will prevent the error by setting sensorCount to 0 if it's None. Depending on your use case, you might want to log a warning or take some other action if sensorCount is None.

Would you like to apply this fix or investigate further?

Same problem here with a S10 X Compact 14.

Please also see torbennehmer/hacs-e3dc#45, some tests are already documented there.

If I can help in diagnosing it by running some more commands, I'm happy to help @fsantini @torbennehmer !
