EDIT: Figured it out. I had left {{ ‘\x00’ }} in the template from another attempt at the template. I noticed after posting my message. I’ll leave this here as a warning to others…lol.
I feel like I should have been able to figure this out but after several attempts I’m stuck.
I have a custom button and want the icon rgb color to be that of a light entity rgb_color value (similar to a light icon). I have this working as desired for a single light with the following template.
styles:
icon:
- color: >
[[[
if (states['switch.light_flux'].state == 'on')
return "rgb(" + states['light.dining_room_rgb_light'].attributes.rgb_color[0]
+ ", " + states['light.dining_room_rgb_light'].attributes.rgb_color[1]
+ ", " + states['light.dining_room_rgb_light'].attributes.rgb_color[2] + ")";
else
return "var(--state-icon-color)";
]]]
But what I really want to use is the value of a template sensor which is this same value (I have a bunch of rgb lights controlled by flux and I’d want to be able to check them all to find one that is on to get this value. I could do this all in the custom button template for each rgb light but I’d rather do it with a sensor value.
styles:
icon:
- color: >
[[[
return states['sensor.flux_color'].state;
]]]
I’ve tried a bunch of variations of the sensor template. This is the one I think should work, but it doesn’t. What am I not seeing here? Why doesn’t this work?
flux_color:
unique_id: flux_color
value_template: >
{% if is_state('switch.light_flux','on') and is_state('light.dining_room_rgb_light','on') %}
rgb{{ state_attr('light.dining_room_rgb_light','rgb_color') }}
{% else %} rgb(255, 255, 255)
{% endif %}
{{ '\x00' }}
