core: Influxdb uncaught exception

The problem

My influxdb instance stopped working for a few weeks. Once I restart home assistant some datapoints are recorded and then the following exception is thrown:

Logger: root

Looks like one of the integrations (generic_hygrostat) is causing the TypeError (data is unavailable until certain components are loaded), however, I would expect influxdb integration to only fail to push that single datapoint instead of stop working altogether.
