Is it possible to ignore or remove low values from temp sensor on restart?

I was working on upgrading HA yesterday and because if that I was stoping and restarting a few times. Now the 48 hour graph for my refrigerator temp sensor has 1.5F values causing the graph to change the display range from the normal range of 35-37F to 0-37 making the graph look flat lined.

I see several possible options but don’t find a way to configure.

1. configure somehow to ignore out of range temp reports. (future fix)
2. remove 1.5 entries from saved state. Don’t know how to do this. but would fix the issue now.
3. configure history graph card with a fixed display range. I don’t see any options for history graph to fix the display range.

Any ideas on how to solve this?

UPDATE: I was able to remove the bad entry using the following sql.

delete from states where entity_id = 'sensor.fibaro_motion_bedroom_temperature' and state = '1.5';

Would still like to know if there is a way to ignore these on restart. Although at least I have a solution now.
