#Hi all. What are the requirements for
ocean zinc
The entities look OK (well, apart from null device_class, but HA seems ot use the original_device_class in the lookup)

same unit and same device class I believe
ocean zinc
All the google results for "why HA showing >1 graph for same unit" seem to be people not paying attention to their uom. Yet mine appear identical, even checked in entity file :/
Hmm, why does device class have to be the same?
dark sparrow
I think it was desired to not show things like battery percent and humidity percent on the same graph, despite that they both have '%' as the unit.
just trying to keep like-types together.
ocean zinc
All these are technically device_class=null (but have different original_device_class)
I'll try a couple that have original_dc=null also, see if they merge
dark sparrow
I'm not sure about original_device_class, but it's whatever device_class that shows up in the entity attributes that matters I believe
ocean zinc
how can I see the device class for an entity, in HA UI?
ocean zinc
thanks. yeah they're all different.
