Optimize InfluxDB query & BugFix

[benni336]

According to https://www.influxdata.com/blog/writing-data-to-influxdb-with-python/
pushing data to influxdb is more efficient by merging data into one string.

Hi,
I am not sure what this change achieves?
It is already collected into a single string before being pushed into InfluxDB?

First I am not an influxdb expert. Just working with it the first time.
From my point of view sequence=[] is not a string but a list of strings. Looking at the debug output that gets very clear.

From influxdb docs I can quote and say your way is not wrong ( https://influxdb-client.readthedocs.io/en/stable/api.html#influxdb_client.WriteApi.write ). You can hand over a list. But than I read the linked article and think one should condense the data string before passing. For example: your list is much longer, as it always contains the name of the measurement variable. Just compare the debug output of our two codes.

If it is all about code simplicity, passing the original dict - just found out from the docs, that should be possible too - would be even "cleaner", than rewriting the values to strings.

Beside that, I would like to suggest to reduce the logging.debug() indentation. I don't think that a debug output is needed for every loop.

Hi @benni336,
I think most of the commit here has already been addressed?
If you can re-base it I will approve :)
The git is now up to date with my current code, so should be easy to approve now.
Sorry
