I’ve added an entry for the PING platform but how do I get it to show the line graph when looking at the entry? Below is what it’s currently showing.
I had other entries for SNMP to get the net in/out and my HASS sql DB size and even those would look like the above. This would cause my web UI to really lag if I went to add a new card to my Lovelace when the card selection popup loaded.
This is not a solution to your problem, but anything that has a unit_of_measurement as an attribute will show up as a line graph, so you might try adding one to the entity in your customize.yaml file.
Strange enough I get both when I add unit_of_measurement: ‘ms’. I’ve never seen this before. I could delete the old entries from the HASS.states DB table and see if that works.
Yes, you get two entities in the history because of the way entities with and without unit_of_measurement are stored in the database. Renaming the sensor should also work.
Entities with a unit is stored in one big table holding all entities with that unit. Unitless entities have their own table.
