One last question hmerk
I just notice that when my string item changes from DISARMED to ARMED_HOME the color doesn’t change something wrong with this (knowing that the DISARM icon reflect just fine the state)
iconColor: '=(items.Alarm_State.state) == "ARMED_HOME" ? "red" : "grey"'
As for the rule it’s pretty much in a working state but ugly and probably people are going to but maybe I posted for others soon that have the same interest.
I apreciate the time you gave for answering me.
