thanks Kyle,
I guess it is also not possible to give a state icon a color by using the styles option then?
info_entities:
- entity: binary_sensor.study_sensor_motion
show_icon: true
icon:
state_on: mdi:motion-sensor
state_off: mdi:human-male
- entity: binary_sensor.security_bathroom_door_contact
show_icon: true
icon:
state_on: mdi:door-open
styles:
color: yellow
state_off: mdi:door-closed
Maybe should issue a request on Github.
Yep, now itâs working 
Do you have any hint how could I modify the background of the card?
Never mind, card-mod helped
Since youâre trying to change both the icon and the style, I think you have to switch over to conditions (rather than the simpler state_on and state_off), but this should do what you want (based on a quick test I did here).
- entity: binary_sensor.study_sensor_motion
show_icon: true
icon:
conditions:
- condition: equals
value: 'on'
icon: mdi:motion-sensor
styles:
color: yellow
- condition: equals
value: 'off'
icon: mdi:human-male
Some of the conditional structure has been shifting, so make sure youâre on the most recent version, as I canât remember what changed when. The yaml above definitely works with v.1.3.0.
Can you share how you did it in card mod? Maybe I can look at it and see if it can be a future feature
This is how I managed to do it:
And as there are several other possibilities in card-mod, I made some more
Ah thatâs something I can build if you want. Would work like the styles config for entities
I donât know yet if Iâd need in the future. Currently I just started to use card-mod, so form my point of view itâs not a must have feature.
But the possibilty to have action on the whole button would be very useful to me
Then you canât add any clickable entities to the card. But I can make it in the future, sure, but it kinda misses the whole idea of the room card
Font-Size for Header⊠can we somehow (probably STYLES but I`m not experienced 
) make smaller font of header ?
for me title are to big and not fit to my all dashboard - thanks in advance !!
The problem is your theme here. Its making the title a little bit bigger. I would recommend tweaking it with card mod plugin or hiding the title: show_title: false.
thanks but my theme have only small modification, even when I switch to default there is no change with size of fontâŠhave a look with comparing to other parts of my dashboardâŠI made only modification on left site where is custom:button-card and all other thing on my dashboard is default font size but room-card have bigger header.
anyway I will try as you wrote with card mod 
thanks !
â=== EDIT ===â
I solved - maybe want to use it also
style: |
.card-header {
font-size: 18px;
}
Glad that worked for you. My OCD keep telling me to tell you the alignment of the title is not correct now
@marcokreeft87 After the latest update i.e. v1.3.6 icon conditions are not working
- entity: switch.fountain
name: Fountain
icon:
conditions:
- icon: mdi:fountain
condition: equals
attribute: state
value: 'off'
styles:
color: red
- icon: mdi:fountain
condition: equals
attribute: state
value: 'on'
styles:
color: skyblue
- entity: input_boolean.test
name: Test
show_icon: true
icon:
state_on: mdi:ab-testing
state_off: mdi:abacus
- entity: sensor.cpu
name: Cpu
show_icon: true
show_state: true
icon:
state_on: mdi:ab-testing
state_off: mdi:abacus
- entity: sensor.cpu
name: {{ states("sensor.cpu") }}
show_icon: true
icon:
state_on: mdi:ab-testing
state_off: mdi:abacus
1 Try using it without the state attribute
2 Thats because input_boolean dont have an âoffâ and âonâ state. You need to use the conditions for that
3 What you are trying to is showing the state as title? Why not just use show_state?
I just saw there is an issue also opened on GitHub regarding this.
Yes I was using conditions for input boolean with attributes which was working fine until the last update, it is no longer working in v1.3.6
If you see the screenshot above I am using show_state for cpu in third column which is showing the temp just fine. I am requesting if instead of using show_state: true which will show the state below the icon we can do something like this so that all the icon aligns (if we donât want the show_state: true for other icons also). I hope I am making some sense 
- entity: sensor.cpu
name: {{ states("sensor.cpu") }}
show_icon: true
1 is working fine. If someone tells you how to use it please donât say it isnt so.
2 Yes, and software changes, so now you have adjust your config to it.
3 Is just a weird request imo, because how would you know which sensor that is ? And why not just hide the name and use the build in state display. Room card wont have this functionality in the near future.
- entity: switch.fountain
name: Fountain
icon:
conditions:
- icon: mdi:fountain
condition: equals
attribute: state
value: 'off'
styles:
color: red
- icon: mdi:fountain
condition: equals
attribute: state
value: 'on'
styles:
color: skyblue
kindly check if its working for you⊠The attribute: state was working before the update but now not working
Are you even reading what I am posting? I told to not use the attribute in the condition, then it will work.
