Your statement about DCC contrasting it with batteries and bluetooth really makes no sense...
- DCC is a control protocol, it is not a battery nor a wireless standard
- Batteries are not a control protocol nor a wireless standard
- Bluetooth is a wireless standard, not a control protocol or a battery.
So none of these 3 things compare to each other.
DCC is clearly the most widely used control protocol for model trains, and technically it is no longer DCC if transmitted wirelessly.
You started this thread complaining about DCC, and say you are a DC guy, but then you want to control your DCC loco's advanced features on DC.
So, if you go to some proprietary wireless protocol, like BlueRail, or RailPro or Train Engineer Revolution (which is a current product), you will again encounter complexity for advanced features.
I will give you this, the early Zimo code was not perfect, and the Zimo system is one of the more complex systems out there, it can do just about anything, but figuring out the "beginner set" of operations was a bit tough, (that's why I have a number of pages on my site on how to get started). The firmware is mightily improved and Zimo keeps improving and adding features without forcing you to buy their decoders or bend to their will as other European DCC systems do.
Not sure what your beef is, but are you actually seeking a solution? I gave you a solution that would be the easiest conversion and answer what you asked, how to control your smoke unit, and not disturb your installation.
Any progress?
