That's true.  I believe this limitation has come up in discussion before.  IIRC the idea is you use the manual (conventional mode) smoke on/off slide switch.  Of course this is not wireless remote control.  But from what I can tell the overwhelming majority of users either love or hate smoke...so it's either always on or always off...period.  When you want to show off to your friends who come to your house you would have to reach under the engine and turn ON the smoke.  Given current events at least your friends will bring their own masks if they don't want to inhale the smoke.
