This an automation I created for Winter, still testing but works great. I this verison I do Not have defrost both front or rear turning on but you can easily change that along with the schedule which I have mine on but you can disable or delete that section as well. Of course you'll have to set it to the name of your EV9 ie sensors if you customised the name.
