Template button-card config with script

Hello,

for a while, I am struggling with a configuration of the button card running a script on tap action. I want to run the script which checks the state of the switch and power consumption and either turn off or show confirmation.
Firstly, I would like to use variables within the card configuration but I don’t know how. I tried to use variables.sensor in label state definition, but it shows only the name of the variable and not the value of the entity.
Secondly, I do not know how to pass variables to the script and use them there.
Can you help me, please?
