Hi,
I just started using HA so probably I mssing something…
I have an non-numerical entity which is created from node-red.
The entity is a string and I would like to show it in history graph bar, but I always get the line graph.
The entity
The history graph card
On the documentation it only says that if “unit_of_measurement” is not defined, the graph is shown as bar.
Thanks in advance!
Cheers
