You have to understand that according to many acharonim (Even Haozer, Achiezer, Chazon Ish, etc.), turning on a light, even using the KosherSwitch, would still be an issur min haTorah. At best, you would be reducing the issur to a d’rabbonon (Mogen Avraham, and possibly, according to Chasam Sofer). You’d actually be better off switching all the bulbs to LED.
This way, nobody thinks it’s muttar, and it would only be used by a non Jew for a choleh, or in a situation of pikuach nefesh, when you wouldn’t want the delay, and when it’s muttar anyhow.
