I am trying to post a measurement of disk usage in bytes using the CURL command. I am using the Rest API to update the state of an entity. I have set up a template sensor in the configuration.yaml file, with an empty state (so that there is a sensor ready to receive the data). It looks like this:
template:
- sensor:
- name: "My Disk Sensor Bytes"
unique_id: my_disk_sensor_bytes
unit_of_measurement: B
state_class: measurement
device_class: data_size
state: ''
Now I try to send some data using CURL form another machine:
curl \
-H "Authorization: Bearer MYTOKEN" \
-H "Content-Type: application/json" \
-d '{"state": "16000000000",
"attributes": {
"unit_of_measurement": "B",
"state_class": "measurement",
"device_class": "data",
"friendly_name": "My Disk Sensor Bytes"
}
}' \
http://localhost:8123/api/states/sensor.my_disk_sensor_bytes
The data seems to correctly appear in Developer Tools, with the correct attributes:
When I display the entity in a standard entity card, it shows correctly the data in bytes as expected:
I would like to display the data here in GiB instead, since that makes the most sense at the moment for this reading. However, I want to keep the underlying data in bytes (so that values can be compared long term, is consistent, and the history graphs work properly, etc). I only want to change the display value in this card.
I tried to click on the entity and edit the unit to GiB using this menu, but it didn’t affect the reading at all:
Is there a simple way to do this?
