Home Assistant 2023.12 added long term statistics to the history graphs.
Out of the box this worked with most of the Geo Home statistics, however a couple of them were missing an _attr_state_class which is required for recording long term statistics, so these statistics were lost after the default data retention period (defaults to 10 days).
Note that long term statistics only starts recording from the moment that a sensor has these 3 attributes (device_class, state_class, native_unit_of_measurement), so it will take around 10 days for the long term statistics to start appearing (which I've been testing on my install).
