Then you can sue the electrical engineer who placed that component into a destructive path. If you use a lamborghini car instead of a lamborghini tractor to plow your field don't be surprised if the car breaks. But if you use a smart meter (which by definition is in the path of the load) to switch something on/off it should not break as long as the load is within the spec of the meter. If it is out of spec of the meter, see above. On a electrical component level the switching element they are using is rated for a maximal temperature. If they continue switching when it is outside of that temperature, because they did not observe a cooldown phase or don't guard against overheating in any other way, it is totally on them. They are operating the switching element outside of the scope, and they should never do that, even if some input tells them to do so.
