My home assistant collects a lot of data and submits them to an InfluxDB. This works well, but some sensors are problematic as they change their value rarely (e.g. some weather data). I see that there is already a “force_update” setting in the backend. It should be possible to configure the force_update setting from the config file for a given sensor or component.
The PR mentioned below implemented this feature.
https://github.com/home-assistant/home-assistant/pull/2365
But the implementation for the sensors platforms is not done.
