Change ICON based on SENSOR state

[edwardtfn]

Please could we have an option to change an ICON/ICON-COLOR based on a SENSOR state?

ICON EXAMPLE:
icon: |- [[[ if(states['sensor.<BLAH-alarm_entity-BLAH>'].state == 'Disarmed') return "mdi:alarm-light-off"; else if(states['<BLAH-alarm_entity-BLAH>'].state == 'Away Armed') return "mdi:alarm-light"; ]]]

Good use cases:

• Change ICON based on SENSOR state. #1183
• Set icon colour by sensor state #1750

you can do things like this in the yaml config.
chip05_icon_color: "{{ state_attr('sensor.afvalwijzer_tomorrow_color', 'kleur')}}"

This will most likely work (I haven't tried myself), however you have a big chance to have issues when using the UI to change settings in your automation, as that will probably overlap it's settings.
Also, on the blueprint there's no trigger for the attribute changing (with rare exceptions). If the state of that entity changes, then the attributes will be updated, but if only attributes changed, you have a chance to not get the icon updated.
This is how it is now.

Hi @NdS-Research-Facilities @edwardtfn I'm affraid it doesn't work indeed. The template sensor does get change on true/false but the color attribute stays the same color on the NSP device.

Is there a workaround to force the color refresh of the icon aswell? When you disconnect the NSP from power, the color does get retrieved correctly.
