it does not reconnect after failure

[antst]

it is easily reproducible.
Just shut down QuestDB for few minutes, and start again. Then QSS component will not attempt reconnects anymore and will not send data, until one restarts home assistant.

Looks like tenacity tries to reconnect for some time and then fails with unhandled exception and then component is dead.
Ideally, I'd assume that it is necessary to handle exception in _retry_data_insertion , and then either skip this attempt to inject data, or keep accumulating data for later send.

Thank you very much @antst. I will have a look at it when I get the chance.
However, I don't have much time at the moment. So any support is very welcome. Feel free to create a PR if you have a direct implementation idea.

[antst]

Actually, I checked, you have already variable RETRY_ATTEMPTS in const.py , which cotrols number of retries. So, for quick fix for me I just set it to very large number ) But, ideally, this needs to be part of config. I will make patch, eventually.
