Hey there @fabaff, mind taking a look at this issue as its been labeled with a integration (influxdb) you are listed as a codeowner for? Thanks!

This is a bug.

With our new set up way, the influxdb component is required to be set up before the platform is set up. This will fail since there's no config for the influxdb component required for the platform and no logic connecting the component and platform.

[awarecan]

quick dirty fix is change
https://github.com/home-assistant/home-assistant/blob/3d91d76d3d87dc28958c70c25cbd7568c8c20d4c/homeassistant/components/influxdb/__init__.py#L92
to

    if DOMAIN not in config:
        return False
    conf = config[DOMAIN]

The proper fix is decouple sensor platform and influxdb component by moving influxdb/sensor.py to influxdb_client/sensor.py

[kylehendricks]

Just to clarify. Is the influxdb component completely broken or is there a way to get it working without changing the code?

[jannau]

@kylehendricks adding a influxdb: section to your configuration.yaml is a workaround to make your sensors work without code changes. As a side effect you will get a "database not found: \"home_assistant\""} error every minute. This is harmless but if you ant to avoid it configure the influxdb component properly.

This bug is still present in 0.103.4
Had to configure influxdb: before creating sensor to make it working.

Same issue. I would like to read data from influx.
