Wont show in group

Still getting head around this

i have these sensor

platform: systemmonitor
name: SysHass
resources:
- type: disk_use_percent
  arg: /
- type: memory_free
- type: processor_use

have this customize

sensor.memory_free:
friendly_name: "Mem Free"
sensor.disk_use_percent:
friendly_name: "Disk Used"

and this group

Hass_io:
name: Hass Server
entities:
  - sensor.memory_free
  - sensor.disk_use_percent
  - input_select.hass_theme

the input_select shows
but the sensors dont show up in group :frowning:

what am i missing

check the names of your sensors

Best to look in the states section of developer tools (the icon that looks like <>

image

my disk used % is actually sensor.disk_used_ in my setup - but check the states area

dirrrrrrrrrrrrrrrrrr

forgot about looking there

thanks
